These are the WORST ENGINES EVER MADE

Some honorable mentions I want to throw in here include the Mopar 2.2L for being a turd, the Land Rover 4.0L for slipping cylinder liners, and the 5.7L HEMI because they do nothing but knock their entire life. Seriously though, there are a lot of bad engines out there, but a lot of it is subjective

The 3VZE Toyota had massive head gasket failures with the very small sealing area at the rear of the block . If there was a half an inch of sealing area between the cylinder and the coolant passage. I have owned and machine shop for over 30 years. We did tons of things for the Toyota dealers, decking the heads and the blocks, but still nothing worked. The paper gasket would be soaking up the coolant in the small half inch area, and would separate from the steel fire ring, and thus, a consistent failure. The real issue is head shift, just like on the 6.0L Ford diesel. The 6.0 just did not have enough clamping load for the high compression, and if you messed with a tuner, your heads were instantly warped .007" I cut hundreds of these heads and never had one warped worse than .010" . The Toyota heads were also moving and that movement was accelerating the deterioration of the paper gasket in that small area. Toyota finally went to FelPro and asked them if they could come up with a possible solution. They created the MLS gasket. Sealant on the head side to adhere to the aluminum, sealant on the block side to adhere to the cast block, and a plate in the middle that allowed for head shift yet continued to seal, since there was no paper to weaken and tear. We were told all of this at a Fel Pro seminar back in the 90's.

[@Scott9181970]

Oddly enough, the 3V 5.4 Triton engines actually brought a whole new spark plug issue with extended reach spark plug tips that frequently seize in place and break inside the cylinder head, requiring a special tool that breaks what's left and pulls it out.

The Oldsmobile diesel was pretty terrible from the factory but they can be built into a pretty awesome engine as long as you pick the right parts. The later DX block with the early pencil injector heads, studded and O-ringed with copper head gaskets, splayed bolt main caps, Speed pro 108M main bearings, King AM-series rod bearings, marine 10 quart oil pan and high volume oil pump. Also converted to internal balance. This combination can max out the stock injection pump at 240 HP with a roughly S366 size turbo. With the head and rotor of the 6.5 peninsular marine engine it can output about 320-350 hp. Internally balanced, they can turn up to 5900 rpm while keeping piston speed at 17 m/s or below. One example of a similar build, although limited to 2600 rpm due to the application is in, a John Deere model A tractor and can be found on KZbin. 240 hp at 2600 rpm.

I worked as a fleet mechanic for Amerco aka Uhaul and dealt with the Triton v10s and trying to send spark plugs into orbit is one of many issues! It wasn’t uncommon for them to completely fail around 60k miles, The exhaust manifolds/ donut gaskets leaking were so common that we changed them almost as often as the oil and you were guaranteed on having half the studs break, no matter how carefully you attempted to remove them! I got so good at welding nuts onto studs that had broken off down in the block, I actually passed the welding test for company I’m with now as a welder 🤣 I’d only had basic experience prior to uhaul!

Put it all back together and ran great up to about 200k before the rear tensioner plastic wore away. Replaced the motor with a 80k motor i had in a wrecked truck.

Oldsmobile had besides the 5.7 diesel, they had for one or two years a 260 v8 diesel that was available as well. It wasn't bad enough that the 5.7 unit wasn't very powerful, the 260 unit was even more gutless and you could even get it in the full sized station wagon with the TH200! We were at one point, with factory approval, swapping engines from the new cars in stock if the customer complained enough and at one point we had more cars apart than the combined total of new and used cars! The dealership was sold to another organization a little while later. BTW, the Ford 2.0 liter sohc should be on this list. (Not the Pinto/Capri engine) The engine used in the Escort/Lynx? made by Ford. It dropped valve seats in many engines before 80k; in the dealership I was at, they wouldn't sell an Escort without the ESP (extended service plan) because the engine failures were so common.

Can't speak for the 5.4l but the 6.8l is far from gutless. My 6.8l V10 is everything I believe a truck engine should be. It makes approximately the same torque as my sister's 2019 6.4l v8 in her ram 2500. I've towed my 8500lbs travel trailer the same route with both vehicles and they get the same mileage.... sometimes the V10 does a little bit better. The biggest difference is how the V10 applies its torque. It comes on early like a diesel and stays there. The v8s you have to run out and blow the fuel mileage. Highway cruising and hill climbs are way better with the V10. The biggest drawback of those year 6.8ls was being paired with a 4speed auto. If you have a 6speed manual you're golden. Paired to a modern 8speed this engine would come alive. Also it's unfortunate these engines were overlooked by the aftermarket. I think there would've been a lot of opportunities to make really high low rpm horsepower and torque with better heads, cams, and superchargers. Say what you will it's my opinion that the V10 is one of the best Gasoline truck engines ever made.

Well the fact that the 6.8 makes the peak torque at 3000rpm(468lbft) vs the 6.4s 4100rpm(429lbft) means it naturally is going to do the hauling job better than the V8 competition.

The 3.5 Ford Duratec engine has an internal water pump thats prone to fail and to replace it the timing chains have to be removed and replaced. Resulting in a 2K or so job that's if you catch it before the coolant ruins the engine

[@danielreigada1542]

Great video until the very end when you called the 2.2 liter Mopar an absolute turd. I had one in my 1988 Plymouth Horizon back in the day. It felt quite peppy compared to other small cars of the day, got 35 mpg and lasted 280,000 miles. The transaxle and clutch on that car were weaker components than the engine.

[@oops1952]

Head gaskets and timing belts were easy fixes. Bang for the buck....they were great!

[@bailey2269]

Easy to stop the fuel spray when the triton engine spits out a spark plug. All you gotta do is unplug the injector and coil for that cylinder. You still gotta deal with the compression noise. But the under hood fire Hazzard is greatly reduced.

[@stephenlacher587]

Northstar was a great engine once they solved the head gasket problem. Have had three of them.

[@pat5882]

Old enough to remember or not, many out there know about the failure of the olds diesel. You are correct with your statement as to why diesel powered cars never caught on in the U.S.. The price of diesel doesn’t help either. The V8-6-4. Not only was there a software problem, microchips were in their growing pain stages back then.

[@oops1952]

Back in the day I could never understand putting a diesel in a luxury car. If a gas engine sounded like that nobody would touch it. If you could afford the luxury why not the gas? Those old diesels didn't have turbos. They were noisy and gutless

[@pat5882]

@@oops1952 yeah, taking and olds 350 gas engine and fitting a diesel injection system and swapping out the heads and no turbo was a recipe for disaster.

[@tyman1014]

I have owned my 2009 F-150 with the 5.4 Triton since new and have had absolutely no issues. Towing, hauling, long highway trips, driving up dirt roads to camp, and of course the normal day to day start and stop city driving. I always made sure to stay on top of all the maintenance and have gotten the oil changed frequently. Just passed 200k miles last month and still have not had any issues since I drove it off the lot. I know a lot of people have not had such pleasant experiences with their Triton engines, but I'm just here to report to anybody looking to buy a used Ford with those engines that not all of them are nightmares.

[@daledavies2334]

Take a look at Detroit Diesel's first 4 smoke engine, the 8.2L Fuel Squeezer. Free standing liners and 14mm head bolts. Many recalls for head gasket failures. Finally came out with a kit to drill and tap the block for 15mm head bolts to get more clamping. That did not fix it. Had a bunch that broke the upper pushrod cup in the adjuster. Those that broke had a shiny wear ring around the top, indicating the ball end was a bigger diameter than the cup. Foreman thought I was full of road apples. On top of this, setting injector balance was very tricky to get right on the racks. Designed for 5 ton delivery trucks, they did not stick around long. If I could find one, I would get a machine shop to make a plate to fit the tops of the decks to stabilize the liners to the out block walls. That would fix the head gaskets. For the pushrods, select parts for compatability. Still leaves finicky tuneup, but the head gaskets and pushrods were the reliability issue.

[@flicksifyr6793]

5.7 Hemi should not even be an honorable mention. Ive never heard of hemis “knocking there whole life” They are very reliable engines aside from broken exhaust manifold bolts

[@tylerfegan1386]

Mine sure has almost 300k on it and over 10000 engine hours. That thing doesn’t owe me anything if it blows tomorrow. Just done exhaust manifolds in it other then that it hasn’t been touched.

[@flicksifyr6793]

@@tylerfegan1386 110k on mine. Got some bolt ons and making 400whp. I beat on her a lot but i keep up with oil changes and other minor maintenance parts. The only issue ive ever had was 2 broken exhaust bolts. Didnt even know they were broken until i went to put long tube headers on.

[@brokenco.official]

As an owner of a 3VZE, yeah they need some extra lovin' in the coolant department.They still run! I work on my 3VZE often as it's 30 years old, but It's still a solid rig.

[@325xitgrocgetter]

The Ford 3.8 Essex V6, especially in front drive applications like the Taurus/Sable, Continental and Windstar minivans. Notorious for headgasket issues. Actually saw one fail in real time when leaving work. A Windstar minivan appeared to have a dead battery as it wouldn't turn over. It did eventually turn over but ran poorly and created a huge plume of white steam from the exhaust...and it wasn't that old at the time. I'd probably add the 2.5 GM Iron Duke...durable but just unrefined, low revving and low power.

[@a4000t]

I ran a machine shop then and the 3.8 ford heads rolled in by the tons. The aluminum the heads used was gummy and didn't have the proper heat treatment. they blew head gaskets religiously. Deck of the head was too thin. Suffered from corrosion from antifreeze. rebuilt many. I remember some coming in the shop warped .030" The 2.5 iron duke was very reliable from what i recall. I fixed some cracked heads but was mainly due to customers over heating them. They were a long stroke motor and didn't rev,but made reasonable torque. The cross flow heads ran the best,but my memory might be wrong.

[@randyferraro3020]

The Rover V8 (3.5l, 3.9l, and 4.0l) is still my favorite V8 to wrench on, it has way more pros then cons. The all-aluminum Buick 215 block was way ahead of it's time. The best 4x4 Land Rovers ever made were all powered by this lightweight and torquey little block. The Range Rover Classic, Discovery 1, and Classic Defender are arguably the best solid axle 4x4s ever made, and the reliability of the Gems and Thor engine management systems is actually quite impressive. They do have one real weakness, and it is overheating them. Maintaining the cooling system is absolutely critical. Most of the slipped liners are results of overheating, and can be rectified with a set of top hat liners and minor machine work on their eminent rebuild. I wish a performance company would engineer and build a performance block for this V8. It is a great little platform to build on, but good machinable crank cases are becoming rare. Still, I would rather keep wrenching on my Rover then repower it with something else.

[@strongereveryday2302]

It's literally one of the worst engines of all time. The rose colored glasses need to come off. It nearly bankrupted the company. Land Rover has been the least reliable automaker in the world for decades.

[@randyferraro3020]

@@strongereveryday2302 One could argue that it was overall mismanagement that nearly bankrupted the company as opposed to a hunk of metal. Machines don't bankrupt businesses, people do. Land Rover chose to throw money at problems as opposed to doing the work to correct their issues at the root of the cause. There are plenty examples of well built, and solid performing Buick 215/ Rover V8 engines. The fact remains, swap 8 parts and retool a boring operation, and you have an engine that is not at all radically different than the old iron GM block that everyone loves so much, but you come in a couple hundred pounds lighter. I don't wear glasses, I see clearly.

[@milny]

@@strongereveryday2302 I've had several LRs, and also 2 v8 Rover SD1s - never any problems with the engine at all on any of them, although placing the coil packs between the back of the engine and the bulkhead is downright annoying on the 4.0. Land Rover is the least reliable automaker because everything else on them is shit ! Hydraulic self leveling suspension - aluminium distribution block and (non-stainless) steel pipes - weld in place and the distribution block costs £2500. Air suspension - first you know that there is a leak in the airbag is when the compressor burns out - £350. Leaks like crazy through the sunroofs. Dodgy ABS (google the 3 amigos). My last LR was a Disco 2 - I gather that the ones subsequently are just a disaster from a maintenance viewpoint ; by the time you get warned off them by an independent LR specialist, it's time to buy a Jeep. I had a Grand Wagoneer which was an utter piece of crap; so horribly and cheaply made with dodgy electrics worthy of a 1970s british car. Jeep Wrangler which was stunningly reliable. Now a hemi powered Grand Cherokee - no problems with the engine at all, runs as sweet as a nut after 100K miles.

[@iBackshift]

6.0L FROD [spelled FROD not FORD; because its a fraud if you buy one], my former boss, all 3 of them went in within a month of each other to do the head bolts [stock power]....bang...bang...bang...one after the other. Back then, $6 grand a pop. I remember saying to him "WHY'd you buy these?" Answer) they were 6 grand cheaper than the GM's. Well Allan, you got yourself an 18 grand keister stretch. hahaha.

My parents bought a brand new 1983 Cadillac Eldorado Biarritz with the 4100HT. Cadillac mechanics jokingly said the "HT" stood for "Have Two" (engines). The car was driven by my mother to and from the health club 10 miles a day five days a week. It was serviced by Neill Lehr Cadillac like clock work. In spite of all that, the engine spun a main bearing with less than 12k miles. Cadillac replaced the engine. Dad sold the Eldorado and bought a brand new Toyota SR5 something or other and never had an issue with it the entire time he owned it.

@@michaeljones3438 We lived on the conrner of Community St. & Rhea Ave. It's a half mile from Niell Lehr. In 1970 I rode my 10 speed (campus green Schwinn) to "Rancho Chevrolet" on Reseda Blvd. I parked my bike outside the front door, walked in, asked to see the brand new 1970 El Camio Super Sport with a 454 that was on the show room floor. After a quick walk-around, a look under the hood and sitting in it for a minute, I asked for a color brochure and left. I was 13.

[@garypeterson9083]

Ford's Triton engine had another bad characteristic. When it came time to replace spark plugs, you can bet at least one of them will snap off in the head. As a mechanic of 30+ years, I had more than my share of them. One pickup had 7 out of 8 snap off. We charged $50 a cylinder to extract them. The plugs were long and skinny, and the hole was fitted too tight to them. Carbon would fill this gap and make it impossible to remove without breaking. Very poor design.

[@JimmyCasket02]

Another one of the major issues with the olds 5.7 diesel was the people that owned them, the average person had/has no idea how to run a diesel or at least older ones, they were being run like a gas engine frequently being run on short trips without ever getting good and hot diesels won’t reach operating temp as quick as a gas engine so they got all sludged up didn’t run for shit but if you took it out and ran it hard for a good 30-40 mins every once and a while they were pretty good then

[@drakec.9327]

My Dad bought a new Olds diesel in 1980 and drove it 13 years, only having to changed the fuel pump. Probably had less than 90,000 miles on it.
