Worst engines ever.

[ACUDANUT]

 My 2000 Chevy with a 4.3 V6 has over 250K and not a single problem.

[miller]

 the chrysler  2.7 in the 98-03 intrepid and other chryslers. junk junk junk and completely killed the resale on those cars .
  gm have a bad one i sell every day  96-00 350 vortec motor , 3.1 's all of them  . 2.3 & 2.4 quad 4's . 3.4 l , 3.8 super charged and non .  I sell these motors everyday .

     

I'm not a mechanic but I have only heard positive reviews for the 3.8 v6, I've heard from many places they can go 200,000 without any fixes, it was the reason I bought a supercharged gen 3 3800.

[Magnumcharger]

My vote is for a Chevy 2.8 V6.... I had a 4x4 S-10 with a 2.8, that thing wouldn't pull a  greasy hair out of a lard bucket!

I agree completely!!

7. Chrysler/Mitsubishi 3.0 V6...Burned oil right off the lot..

Every time I am sitting at a light, and see a big puff of white smoke several cars ahead of me, I always think to myself early 90's Chrysler minivan. Those are good for one thing. A mosquito fogger.

I had a 92 lebaron convertible  3.0  they called me  007  because i had a smoke screen everywhere i went    
  great motor as far as power and ran up to 200 k on it  but used a quart of oil a week  LOL

AMC 401,360
Oldsmobile 307
ford focus 2001  2.0
Chevy Iron duke  should have been the iron Duece
Ford fiesta

on the  97-2001 escort  2.0 sohc split port , and the 00 -up focus same motor 2.0 sohc
 they are junk , I could sell them every day    they like to drop values regularly  blow head gaskets also .

   funny thing is on the 2dr version  DOHC motor 2.0 you cant destroy , everyone has them on the shelf and cant sell them they are so good .

the biggest problem with the 3.8l is the orange anti freeze GM uses eat the intake and head gaskets away  , never ever use that stuff it horrible for the inside of your motor .  ALso the intake and intake gaskets are junk in the first place , replace the intake gasket asap with the fel-pro fixer kit and get the orange anti freeze out of the motor asap

I find it interesting in hearing all the engines Stu gets to sell out of the yard. That shouold be a really good indication of whats junk and whats not................ Guy I work with has one of those old Ford Escorts  turned 300000 miles on it a while back. He decided to get a new car and sold it. Still running with no troubles at all.
I bet he dont get that out of his new Focus.

yeah a girlfriend of mine had one bought it new and everything  took care of it it blew at 80k

[derailed]

6.0L Powerstroke Diesel. Worst engine I've heard about. I've got a few friends with them, and most of them have blown the headgaskets at least once, not to mention the EGR problems, high pressure oil pumps, ETC.

I think the 03s are the ones that your taking a gamble on. They straightened out some issues with the newer ones along with a stronger trans than what was behind the 7.3.

What years had this problem? Mine is a 2005 (tail end of the 3800s life) so did they fix the problem by then?

My Vote?   The GM  305....I've seen so many with cracked lifter valleys

is your a metal or plastic intake , i think around 05 up they went to a metal intake and solved all the problems

THE 6.0 Ford PS are junk . The transmissions are okay though.
The epa forced them to ditch the 7.3's diesels and that's were the problems started. They were not not Ford's Diesel but rather International (Navastar). Ford got tired of jacking with these Navastar engines and finally one built thier own. BTW I hear Ford own's Cummins   I hear the New Ford Diesels are great.

[DodgeByDave]

The worst ever is the Cad Northstar, for reasons mentioned and some others not.

Read this thread if you own a NS or someone who does. It could save them thousands.

[Manfred318]

I was just going to say the Cadillac Northstar. We have had two of them and both have blown a head gasket and cracked heads. The first was a '99 SLS it went with about 86k on it and the last one was an '03 SLS and the head gasket went on that one with 128k on it.

[greenpigs]

  The Vortec head swap one a gen 1 small block Chevy is one of the more popular things to do,you will need a compatible intake. Most people building a budget SB go the junkyard route for heads and are upgrading the intake anyways so its no big deal.

dumbest design ever to put the starter in the middle of the engine below the intake manifold     

[Cooter]

I knew there was another engine I missed..Furd Exploder 4.0 SOHC engine...5 Timing chains one of which, the engine has to come out to replace it in the REAR of engine...

yes and re timing those with the front and rear timing chains and the stupid jack shafts running through the engine connect all the chains is a night mare

[Akron_Charger]

i would say the 90s Chevy 3.1 had one in my 99 Monte Carlo and it blew a headgasket twice

[dpm68]

Speaking of dual front and rear timing chains, has anyone mentioned the Land Rovers? I have a friend with one who is about ready to send this pig to the crusher. I think his is like a mid-90s Discovery series and it is sucking all his money away. I have since heard no good at all of these.

Yeah, i have one, a 99 no problems with the chain yet, but i added the restrictor and had to do the manifold gasket fix.  Whe the heck they made the intak in two pieces is beyond me.   I was taking it apart and couldnt see any reason for it.  They made that engine way more complicated than it needed to be.

That's to keep people like the ones on this forum from working on their own cars in the back yard like they did 30 years ago...The "Shadetree" meck-a-neck is long gone....

[dpm68]

Yes, planned obsolescence is the way of the modern world. That said, I'm going to buck the trend and head back downstairs to finish wet sanding a customer's '66 Mustang - with NO MOTOR ISSUES...
