worst engines ever made
Thought id start a thread n c peoples thoughts on what the worst engines in vehichles are. Heres my opinion
1. 2.4 quad four dual overhead cam 2. 5.7 olds diesel 3. 5.4 ford ticking triton 4. 5.7 tickin hemi 5. Straight 6 4.0 in jeeps pistons chip 6. 6.0 powerstroke 7. 6.5 turbo diesel and 6.2 8. 7.3 idi turbo headgaskets and valve guides 9. 4.3 vortec 10. 5.9 magnum 360 These are my opinions and experiences based on my hobby as an engine rebuilder and based on what ive seen first hand. Foreign engines were left out.:jump: |
3208 Cat,
3408 Acert. 400 B cam Cummins. Cummins ISX (depends on the day if they are POS) 6.0L Powerjoke. 6.4L Powerjoke. Anything with a DPF or Egr. Detroit Series 60 are just a PITA to work on. Geez, I thing the 5.4 Triton and 5.9L 360 are good engines. One truck on the ranch has 230K with the 5.4 and my mommas durango with the 5.9L had 290K and still a tickin.. If you listen very closely everything ticks.. |
I agree on the dpf and egr... and detroits are a pita leak oil bad and parts are expensive. But in my experience the 360 is inferior to the 318 magnum imo but neither are like a 6.5 where it will just snap a crank unexpectedly or block will crack. As well as the issue with the 24 valve 5.9 block #53.:pca1:
|
I like the 318, and 302's the best. But their are only a few bad #53's it was just that block run that had a bad casting mold or two out of a 100 or more molds.. Also I needed to add Maxxforce. Dear lord save us all...

I will have to disagree with you on the 4.3 Vortec,I have a 85 gmc sierra with the first vortec,it came with 4-Barrel carb and headers factory.This truck was bought buy a old man that never took care of it,then let it sit in a barn for five years.My nephew bought it got it running,ran the dog shit out of it for a year with out ever even changing the oil from when the old man parked it.Then I bought it and have put 50'000 on it with no issues and I am getting 21 mpg.:rocking:
|
I prolly shoulda been more specific sry the ho 4.3 vortec
|
Common rail cummins I know of 2 that self destructed I will second th 6.0 and the ticking triton
|
HO 4.3 agreed they blow intake gasket.

Ive nvr worked on a common rail cummins so i cnt say yay or nay.. ive heard the 5.9 common rails can take some high egt abuse good...as for 6.7 idk a clue except there so restricted with dpf and egr they get 11 mpg and ive seen a article in diesel power on a 6.7 piston went to shit after 22,000. But they are all good engines in my opinion.
|
I know one guy had an injecter break and eat the engine these are 5.9 btw and another that had the egr? I think I am telling that right any way egr f****d up and sent #5 rod out the side of the block. The older engines didn't have any of the crap the common rsils do and the 24v and older engines have heavier parts ie crank and rods that's why they tend to last longer parts are less money too
|
yeah, not all 53 blocks from the old vp44 24v's are bad... I seem to have a good one... 239k miles on it and it has had a hard life. no cracks :tu:
I have however heard of some 55 blocks and storm blocks cracking as well in the same spot. it's not just the 53. but 53 has had more instances of the crack. from rumors I have heard, the block mold shifted over a bit causing a thin spot in the passenger side of the block which tends to crack. vp44's aren't the best pumps either, but if you get to know the trucks, you can help the vp44 live a nice long life by keeping proper fuel pressure and fuel lubricity. As far as bad engines go: 3.5L ford ecoboost, early 6.5L GM turbo diesel GM LT1 5.7L had a crap design for their distributor. they placed it on the front of the motor behind the waterpump, so when the water pump went out, it took the distributor out with it! not to mention in the old LT1 camaro's it was a good 8hr+ job just to change plugs and wires on those cars. wouldn't mind one in my S10 though. has a bigger engine compartment than a camaro. |
6.0 powerstroke gets my thumbs down
|
The 350 OLDS, you don't see them:humm:
|
8.2 V8 detroits ...... I hope they are all in the scrap yard by now. When the detroit dealer wont even work on it something is wrong.
I will disagree with the Jeep 4.0 motors ... ive owned over a dozen jeeps with 4.0s... they may tick but ive seen em tick for over 100k after they started ticking and never give any troubles. |

I will disagree on the jeep 4.0's. My mother-in-law had one with 260,000 miles on it, run great. Overheated one time because the rad sprung a leak while pulling a trailer. When we puller the head off for inspection, the cylinder walls were terribly worn, and a lot of piston slap. But this thing ran great! Anyways.....
How about the Detroit Diesel 4.3L V6?? |

How about the Detroit Diesel 4.3L V6?? 4.2 ford V6 5.4 ford although have made my fare share of money Changing spark plug threads in them Had one that I changed 3 of the in 2 weeks time (anything Chrysler in the last 2 decades is crap Oh and I am with Cviola on them 4.0s them thing are like a timex takes a licking and keeps on ticking had a freind with one never change oil in it as it leaked like a seive had 500,000 + on it running straight 50 weight in it |
Wasn't real fond of the V6 that was in the Oldsmobile Silhouette minivan we had for a while. LOVED the 2.2L turbo in my '85 Dodge Lancer, and the 2.5L turbo that was in my '89 Spirit. Was pretty impressed with the 7.2L V-10 that was in our RV, too. I don't recall ever truly hating any of the engines I've had. Maybe I've been lucky.
