That makes it very difficult to get them clean, so they’re hard to rebuild, and that’s a real problem, because new lifters are very expensive. The original block was changed in ’95. The early crank gear has caused problems for many rebuilders. The threaded plugs on the top tend to leak, too, so they should be removed and reinstalled with sealer on the threads. The new 95TM-AB casting had two more bolt holes on the passenger side and two more on the driver’s side for a total of eight on the right and 12 on the left (see photos above). Rebuilders should expect to rebuild or replace most of the rockers. Even though the V8 would reluctantly not be our first choice, it ranks second only by a slim margin. The dipstick hole on this block was enlarged to about 0.435?, too. There’s a passage in each rocker that allows oil from around the rocker shaft to migrate out to the small hole in the top of the pushrod socket, but it’s wide open on the outer end so there is no pressure there to feed the oil down into the socket. Step on the gas and the response is immediate. 1990-’94 Ranger, Explorer and 1990-’96 Aerostar. The dipstick hole measured about 0.380? These pushrod engines are all conventional 60° Vs with cast iron blocks and heads. Ford is making the decision even more difficult by introducing its second-generation 3.5-litre EcoBoost for 2017, a twin turbo we’ll be testing soon. As an option that ranges in price from $750 to $2,950 depending on configuration, though, the new EcoBoost can be costly — but it will also be mated to a new 10-speed transmission co-developed with GM that gets a Tow Haul and Sport mode. Having this pin in the side of the lifter required a special design that had an inner and an outer body, so there’s some space in between them that can trap a lot of debris. The XL2E-BA casting that was introduced in ’99 was used up through 2000 when the OHV engine was discontinued. The two steel balls in the lifter valley that are used to plug the oil galleries must be removed in order to clean the block properly. Stay up to date by signing up for the Engine Builder newsletter. Indeed, Motor Trend registered 6.1-second runs to 60 mph with the new 3.5 EcoBoost. At least until the diesel, and the hybrid, finally arrive. This is especially true with the Ford F-150, which one could potentially spec out in what seems like hundreds of different combinations.

That’s the story on the 4.0L. Apparently the small hole in the pushrod socket that intersects this passage is supposed to meter oil down into the socket somehow, in spite of all the motion that’s trying to sling the oil out from the open end of the passage in the rocker. The piston was revised again in ’98. See Chart A for information. The pushrods and rockers on the 4.0L tend to show a lot of wear, even on engines with low miles. The 4.0L originally came with a piston that had a small dish that measured about 2.40? Engineers revised the block, changed the heads, played with four different cams and used four different rods, so it would take about 10 short blocks and even more long blocks to rebuild all the combinations exactly the way Ford made them over the last 11 years. There have been some problems, especially in Ford Focus RS models with the cylinder head gaskets failing. Some rebuilders weigh each rod and others sort them based on the appearance of the weight pads on the bottom of the big end (see photo). boat and trailer with astonishing ease. Ford had planned to discontinue the RWD Aerostar shortly after the FWD Windstar was introduced in ’95, but when it was realized that there were a lot of fleets that still liked the Aerostar, the company decided to keep on building it. The Ford F-150 is, once again, Canada's best-selling vehicle through May. The crank was revised again in ’97. Hooray, more choices! Ford offers this revised gear (p/n F5TZ-6306-A), but it’s readily available in the aftermarket for a lot less money. This approach looks good on paper, but you still need to know if the vehicle came with EGR from ’93-’95, and that’s not always predictable based on the year and application, so be sure to ask the customer before selling one of these engines. There have been four different cams used over the last 10 years. All of these engines had four studded mains that were used to hold the windage tray in place under the crank. This crank appears to be the same as the 97JM-AC, but there’s a noticeable difference in the bobweights. Some rebuilders have commented that making the 2.6L into a 4.0L was a lot like making the 265 Chevy into a 400; it’s a good analogy on a slightly different scale. If it were my money, the 2.7 — a $1,300 option on average — would be third choice. In fact, “It will burn the engine down in a few thousand miles,” according to a Ford engineer who worked on this engine program. The EcoBoost 3.5L is a twin-turbocharged V6 engine from Ford Motor used to power midsize and full-size cars, pickup trucks, supercars and utility vehicles, or more commonly known as SUVs. Doug Anderson. With a 3.3L Ti-VCT V6 engine, 17-inch silver-painted aluminum wheels and more, the 2020 Ford® F-150 XLT is in a class of its own. The rear seal on the 4.0L has always been prone to leakage. There have been three different rods used in the 4.0L, including the FBOCA, the FBOCB and the 7AE, but the forging numbers don’t tell the whole story because the weights are not consistent with the numbers. Each truck was a SuperCrew with 5.5-foot box. Ford says they should be torqued to 80 ft.lbs after resealing them. Use the F3TZ-A for the ’93-’95 Rangers and Explorers that don’t have EGR; and. The 95TM-AD casting that came out in ’95 had the heart-shaped, fast-burn chambers that shrouded the intake valves. Official Ford order guides have leaked for the 2021 F-150 Raptor and Tremor packages, confirming that the high-output 3.5-liter EcoBoost V6 will return as the base engine in Ford… The dish looked a little bit different this time, but the real difference could be seen from the bottom of the piston. on. For those of us who embrace new technology and either trust Ford’s engineering technology or purchase extended warranties or both, the 3.5-litre EcoBoost is the No. In ’97, the flange for the flywheel was changed from a six-bolt to an eight-bolt pattern. Second choice, and one that will require less option money on the $40K-$60K purchase of a pickup, would be the 385-horsepower 5.0L V8, a tried-and-true small block that eschews turbo technology for good ol’ fashioned displacement. At 375 lb.-ft. of torque, the 2.7 edged awfully close to the 420 lb.-ft. in the outgoing 3.5L, something the gen-two engine will correct, distancing itself that much further from the 2.7 with its higher torque. While the overall average registered highest among the engines at 15.5 L/100 km, the V8 used only 0.9 litre more on average than the 3.5 turbo. It was also used in the Aerostar engines in ’97, because Ford finally did go ahead and certify a new calibration for the Aerostar with the fast-burn head, even though it ended up being the last year of production for the old RWD van. There’s also a more connected feel with the V8 that the V6 turbos somehow lacked. The next-generation Ford Ranger Raptor has shown its sharp new face and petrol V6 engine for the first time… and it’s dressed up for Australia.. That’s right, the 2023 Ford Ranger Raptor has been snapped testing in right-hand drive with a petrol V6 engine under the bonnet, suggesting Australia should get a petrol-powered Raptor for the first time. They both had a six-bolt flange for the flywheel and a short, angled notch machined in the step at the back of the snout, but there was a subtle difference in the length of the notch, depending on the casting. The original 90TM casting had an oval-shaped chamber that was slightly bigger in diameter on the intake side. Ford F-150 with the 3.5-litre EcoBoost engine The 420 lb.-ft. of torque — increased to 470 in the new engine — simply gives the F-150 all the power it could ever need unless you’re Tony Stewart. The ‘90-’96 crankshafts can be interchanged as long as the matching crank gear is used, but always remember to stake the early gear in place in one way or another whenever using a 90TM crank with the short keyway and the notch in the step. It was replaced by the 97TM casting in ’97, but it was the same, so they can be used interchangeably. The 97JM had 880 grams on all the bobweights while the XL2E used 850 grams for cylinders 1, 2 and 3 and 842 grams for 4, 5, and 6, so there’s an overall difference of 4.3%. It was replaced in ’93 by the 93TM-AA casting that was exactly the same. The original crank casting was the 90TM-AB. Surprisingly smooth at idle and under acceleration, the 2.7 is the fuel economy leader, and it hustles the truck along briskly. We had always believed that this change took place sometime during model year ’95, but my best sources tell me it was actually made late in calendar year ’95, which means it was a model year ’96 change. It’s not the sound, however, that matters in a pickup, but the marriage of towing capability, power, refinement and fuel economy; the 3.5 EcoBoost ranks as the towing champ, able to haul 5,534 kilograms. Some rebuilders are building every application by the book, some are consolidating the FOTZ-B with the F3TZ-A and keeping the other two applications separate, and others are combining the FOTZ-A and the FOTZ-B with the F3TZ-A and keeping the F3TZ-B separate. In ’96, the crank came with a full-length keyway and it had another step machined into the raised area at the back of the snout. They can be identified by the letter “U” that’s located on the top of the right rear/left front exhaust port. It was used along with the 90TM/93TM heads that had the oval-shaped chambers, so it was found in the Rangers and Explorers from ’90-’94 and in the Aerostars from ’90-’96. The V8 also sounds the best of all three, of course, and it didn’t come with any of the shifting confusion that was occasionally detected with the larger EcoBoost. Plan on buying a lot of new pushrods, too. Ford has used three different pistons in this engine over the years. It really gets interesting when you get to the camshafts. We didn’t test the fleet-orientated base V6, but instead stuck to the trifecta which most F-150 buyers will consider: the 2.7L EcoBoost, the 3.5L EcoBoost and the 5.0L V8. Ford has used four different cranks with five different casting numbers in the 4.0L. bore and a 3.307? on the 95TM/97TM castings. With all that in mind, let’s take a look at the 4.0L and see what Ford has done to make life more interesting for the rebuilder. There have been three blocks used for the 4.0L. It’s appreciably smooth and quiet with just a hint of desirable turbo whistle under light acceleration. Use the F3TZ-B for the ’93-’95 engines that came with EGR and for all of the 4.0L engines from ’96 through 2000, except the ’96 Aerostar that should still use the FOTZ-A. The 420 lb.-ft. of torque — increased to 470 in the new engine — simply gives the F-150 all the power it could ever need unless you’re Tony Stewart. The only exceptions are the rods that can be used in matched sets, no matter when they were made, the 90TM cranks with the notches that can be interchanged with the 90TM/96TM cranks with the long keyway as long as the matching crank gear is used, and the various cam consolidations that are open for discussion. There have been three distinctly different heads with five different casting numbers installed on the 4.0L since 1990. 1 choice — underlined even more so with the introduction of the second-generation, aluminum engine.

If this were 1970, jumping to the EcoBoost from a V8 would feel like driving a big block over a small block. In ’95, the angled slot that was machined in the step at the back of the snout was increased in length. Ford continued to use the early heads on the ’95 and ‘96 Aerostar because they still came with the early calibration, so rebuilders must do the same. Shop the latest Engine Builder merchandise. They are almost impossible to remove from the top, but they can be driven out from the bottom by coming up through the oil holes in the mains. Unauthorized distrbution, transmission or republication strictly prohibited. It’s probably a good idea to include the matching gear or some information explaining the differences along with the crank kit in order to avoid any problems in the field. When the head was redesigned in ’95 with the heart-shaped, fast-burn chamber, the piston had to be changed to maintain the same compression ratio with the new, smaller chamber, so the dish was noticeably larger (3.10? It was replaced by a SOHC engine from this same family at the end of model year 2000. © 2021 Postmedia Network Inc. All rights reserved. The new 97JM-AC casting came with an additional step, the long keyway and an eight-bolt flange for the flywheel. This has been a common engine in some of Ford’s most popular vehicles including the Ranger, Explorer and Aerostar, so there are over 3 million of them on the road and plenty of business waiting for the shops who know how to rebuild them and make them live. Apr 1, 2001. This was the same casting that was used in the SOHC 4.0L for ’97 and ’98, so the cranks from both engines can be interchanged, in spite of the fact that Ford gave them different part numbers. However, it could become an issue when selling a crank kit because the gears are not interchangeable, so you have to know which one the customer has in order to supply the matching crank. We wouldn’t recommend using the F0TZ-B with an automatic, though, because the extra advance in the cam may affect the way the engine behaves with the torque convertor, so you should throw these cams away if you’re going to consolidate all of these engine applications. Towing power at 4,899 kilograms is only slightly less than the 3.5, too. Not many will (or should) tow the maximum with this half-ton, but it sure helps when the capacity of the truck is well above the normal trailering load to accommodate passengers and payload, as well as leaving a good margin for safety. The tips can be ground if they’re not worn too badly and the sockets can be repaired by installing a special insert that’s available along with the tooling needed from Silver Seal (800-521-2936) or Goodson (800-533-8010). The notch in the original 90TM-AB shaft was 0.420? Rebuilders should also be aware that there are new aftermarket heads available from several different sources. There’s pressurized oil at the rocker shaft to lubricate the rockers, but there’s no direct way for that oil to get to the pushrod sockets. Unlike most other OHC V6 and V8 engines that drive both overhead cams directly from the crankshaft with a belt or chain, this engine has an intermediate jackshaft in the middle of the block where a pushrod cam would normally be located. Both ways seem to work, so it really doesn’t matter how you go about sorting them as long as you keep them in matched sets. The roller lifters are held perpendicular to the cam by a steel pin in the side of the lifter that slides up and down in the groove that’s machined in the side of the lifter bore. Installing the light crank in a ’97 engine with the heavy pistons will overbalance the assembly and add to the vertical imbalance that makes the steering wheel shake, so don’t use this light crank in an engine with heavy pistons. These castings were used on the Ranger and Explorer from ’95 through ’97 and on the Aerostar in ’97. Each one can be identified by the number of machined rings around the barrel and their proximity to each other, but the applications and possible consolidations can be pretty confusing, so let’s start with the original part numbers along with their applications and go from there. For old-school traditionalists wary of turbo technology or those who like things simpler, your engine has eight cylinders. In our test, it hauled the 3,600-lb. Ford solved this timing problem in model year ’96 when they machined the crank and the gear for a full-length Woodruff key that indexed the gear on the crank and held it securely in place. All of these heads have the letter “A” cast into the head right above the right rear/left front exhaust port. boat and trailer, consumption registered a decent 15.3 L/100 km. Some of the later heads have cracks around the oil drainback holes and quite a few are cracked in the chambers, so they should all be carefully inspected before being rebuilt. This groundbreaking engine pulls from the collective power of gas and electric energy, because teamwork gets the job done. Rated at a rather anemic 210 horsepower, the 4.0L SOHC V6 is not exactly a high output engine. Ford introduced another new head in ’98. Automatic start/stop technology comes standard with the 2.7, but unfortunately it can’t be set to stay off (though will remain off in 4×4 mode). Each one is unique in some way, so none of them can be interchanged. Most of them are scuffed and worn on the tip due to the lack of oil in the socket. The key can be a little hard to find because it’s a metric size; it’s available from Ford as well (p/n W702979S300). 1995-’97 Ranger, Explorer and ’97 Aerostar. Ford 4.0L V6 Engine. The FOTZ-B is very similar to the FOTZ-A, except that the timing was advanced 10° to move the torque curve around in order to make it feel a little better with the manual transmission, so the FOTZ-A should work fine with a stick; the difference is so slight that it probably won’t even be noticed. Be sure to warn your assemblers and your customers so you don’t have to pay somebody to take it apart and do it over again. vs 2.40?) Which cams can you interchange? Advertisement. The 3.0L Ford pushrod motor has been around for nearly 20 years. Consider this a disclaimer and make your own decisions based on the information available and your own experience. The first one had a small dish, the second one had a bigger dish and the most recent one is a lightweight version of the deep-dish design. It’s been used in several FWD applications including the Taurus/Sable, the Tempo/Topaz and the […] The crank gear was timed to the crankshaft by the small tab on the back of the gear that fit into the shallow notch that was machined in the step at the back of the snout. Most of the differences are specific to given years or applications or both, so they can’t be consolidated or interchanged. We suspect that there are two reasons for this problem: (1) The material in the rockers appears to be too soft, so they wear on the tip, and; (2) there’s not enough oil getting to the pushrod socket, so it gets worn out, too. Toyota makes it easy, offering two V8s but selling mostly one, and Nissan presents just one V8 in its half-ton. Otherwise, you will have to specify the gear that needs to be used with the crank that is actually boxed in the kit. That all depends on who you ask. Both turbo engines are well insulated from noise and vibration, just like the V8; but the V8 simply feels more natural, more relaxed, more at home in this truck. It’s pretty straightforward if you keep the castings straight and pay attention to the details. This helped the converter “light off” sooner, so it did a better job of reducing emissions during the critical start-up and driveaway phase of the EPA emissions test. The original 2.6L engine was replaced by the 2.8L, which was upgraded to the 2.9L and then finally bored and stroked to make it into the 4.0L that was used in the Rangers, Aerostars and Explorers starting in 1990. However, Ford chose to use the early pistons and the early heads with the 97TM block so there was no need to certify a new calibration for just this application. So if you trust Ford’s engine development (and there’s little evidence to suggest you shouldn’t), or you don’t do a ton of big-time towing and want an ideal blend of performance and economy, the 2.7 is your engine. Dealing with all of these different cams can be a problem, because there’s no absolute right answer short of rebuilding each engine exactly the way Ford built it, but that creates more applications and more opportunities to sell the wrong engine, so every rebuilder needs to consider the alternatives and do what works best for his shop and his customers. Now with direct and port injection (to minimize carbon buildup on the backsides of the intake valves) the EcoBoost spools out power quickly, without hesitation, and all of it available at low rpm — an ideal scenario for towing. The 2.6L block that began with a 3.54? stroke by the time it grew into the 4.0L. Our best fuel economy over the test was 10.3 L/100 km on the highway, with a combined average of 12.2 L overall. EcoBoost or V8? Surprise! in diameter. long while the slot in the later 90TM-AA casting was 0.673? Ford has made a number of changes and improvements to the 4.0L since it was introduced. Best prices, Free shipping 818 767-6603 Understanding this mid-year change helps explain the mix of castings that we have seen in these engines, but it really doesn’t make any difference which crank you use in a ’96 as long as you use the matching crank gear. Ford offers a repair kit that comes with a sleeve and a seal (p/n F5TZ-6701-A), but it costs about $50 at the dealership. After driving three 4×4 F-150s back-to-back over several weeks — each truck with a different engine — it’s clear the behaviour of each engine acts as differently as unsupervised kids in daycare. Impressive. Both of the pan rails on the 97TM-AA casting were wider and there were two more gussets added between the pan rail and the horizontal rib that’s right above it on the passenger side. The cracks on the top can be found by Magnafluxing the heads, but the porosity problems won’t show up unless the head is pressure tested at about 70 psi. While towing a 3,600-lb. In the outgoing truck, the six-cylinder mill cranks out 450 … Just like the 2020 model year, the 2021 Ford F-150 Raptor will use the high-output engine. With that in mind, it’s probably not a good idea to swap these heads back and forth with any of the earlier castings. Choosing the right pickup is hard enough – figuring out which engine to pick when ordering a brand-new truck can be even more of a challenge. Yes, the exhaust might sound a bit tinny, but it’s not unpleasant, just not as natural or as deep as the 3.5, and of course not nearly as satisfying as the V8. There is nothing to hold the gear in place against this step until the damper is installed, so it wants to slide forward and jump out of time during assembly, test and installation. 2.3 EcoBoost Engine Problems Ford’s 2.3 EcoBoost engine dates back to 2015. While the transition from “off” to “on” is immediate the moment your foot comes off the brake, some buyers might nevertheless find the feature intrusive. It sounds great. bore and a 2.63? You may want to consider flame-hardening the tips, too. stroke ended up with a 3.952? While the sound might be piped in on models with Sony stereos, it’s not acoustically fake, rather “digitally refined” from what the engine actually produces and sent through the truck’s speakers. The ring grooves were moved closer to the crown to reduce the crevice volume and the rings were narrower, too. We recommend installing them in every engine in specific locations according to the diagram so the installer doesn’t end up moving them around and disturbing the torque on the main bolts in the process.
