I don't have the first to offer.
I've not owned one that was completly sorry. I attribute them to being wore out
But in your opinion's what are the sorriest engines produced?
I mostly had headgasket and intake gasket problems.
What are the worse production engines built.

Tumba

 

Whatever was in my sisters Pontiac Phoenix in the mid 80's. It was a real dog.

 

Whatever Chrysler was putting in their minivans. You know, the ones that never stop smoking?

 

Chrysler definitely needs to be on the top of the list especially with the 2.7L V6.

 

The vega aluminum engine was without a doubt the worse engine made. The chrysler 4 banger that was in the mini vans was a close second.

 

What about that 4 cylinder they use to put in the Escorts. Weren't they made by Bic ? That lighter company ? The flint would burn up @ about 90,000 miles..

 

So far I already new about the pontiac QUAD4. Afriend of mine had one.
The Dodge minivans I thought it was just the A/C.
Ive been told about Vega aluminun
Bic! They probably did try the engine biz at one time:llol:

 

I once dated a girl who had a 3 cyl GEO! It was like ridin with a chainsaw motor under the hood! ...............

 

Also, Chrysler's 2.2L that devoured head gaskets...

Chevy's 2.8L V6 was never known to be a runner, but my father had an S10 w/ a 2.8 that had 240,000...

 

i had a grand am with quad 4. it ran ok.. i guess i got lucky.those were notorious for headgaskets right?

 

And cam chains or belts or whatever they have.
When they run right they're fun to drive.

 

i remember it didnt have a regular pcv valve. it had some other kind of weird setup. oil always looked milky. every mechanic i brought it to said it was fine just a bad design.

 

Mitsubishi 2.6L 4 banger - used a lot by Chrysler (oil control issues)
Chevy Vega 140 (aluminum block without liners and iron head)
GM Quad 4 (bad timing chains)
Early Ford 3.8 V6 - (head gaskets)

 

Heres another vote for the chev 2.8.

 

the 4 banger they put in the 80s s10 wasnt so great either. i think it was the 2.5
