Chrysler 2.7l

[CamaroAdam73]

lol i would never just simply replace bearings and ship it out knowing full well it will fail again very soon, the journals get pretty scarred up when a bearing spins anyways...you'd have to be a complete *ss to think it's ok to just put fresh bearings in.

Alright i put the engine up on a stand and cracked her open....
Every rod bearing spun, two of them where no longer there anymore.
Most of the main bearings where shot, two of them where just about to start spinning.
Bottom end was caked full of sludge, I've seen 45 year old small blocks retain less build up.

Does anybody know if the water pump problem has a remedy? Does it just leak from the gasket or what?

You are going to have to do a major clean job in that block, I would cut the main caps, line bore the block, hone the cylinders if not scored, hot tank it. The water pump fails IMO because the timing chain tension is to much for the bearing.

Fox80, keeping what you said in mind i decided to give the top end a good look through before going any further, the cam bearings where going bad too.

He finally decided to go with another engine, we'll be installing a 3.2 into the car.

IMO opinion I've opened up a few cans of worms on them engines

The 3.2's ?? I thought they where a much better platform than the 2.7s

 

[Fox80]

No I meant it in response to you deciding to scrap the original motor, a motor swap is not a bad idea, I meant by agreeing to fix some of these motors made major headaches for me like I described above. Not that they can't be fixed but the cost would far outweigh the value of the car. You can spend over a grand just servicing the heads, new chain, chain guides, water pump, chain tensioner etc

You'll like this, idk what the deal is around here but nobody has or can sell me the cam bearing/caps + cams, IF we went the rebuild route we'd be almost 2000$ on new heads alone, yeah hella cost to repair an engine that could possibly fail again at under 100k, self explanatory heh.


Another question for ya if you dont mind fox, are you familiar with the Gm 2.2ls? I've worked on a few of the newer 2.2ls which are DOHC, are all the 2.2L engines DOHC design?

 

[Fox80]

Oh yea the 2.2l is GM's most used motor, the "iron duke" version is one if GM's first four cylinders. No they have not always been DOHC at first they were SOHC chain drive, then the "vortec" 2200 was belt drive SOHC, now the new version is DOHC. The SOHC is probably one if the most reliable easy to work on motors, the DOHC version is used in sprint car racing. On the Chrysler I believe the cam components have to be bought through the dealer, they may not be available anymore, it was five years ago when I did the re-ring head service in one of them parts may not be available anymore, but I'm pretty sure the owner of the car ended up getting everything from the dealer. I don't remember everything about it, the mains in that motor looked great but the rod bearings were a little opened up, if you lose the rod clearance you starve the cam tensioner that allows the cams to come off time that bends all the intake valves, nice thing about being in the rust belt not one of them cars are worth the expense of fixing the motor.

LOL i'm up in western PA, this F'ing car DID survive the rust. 83k millage, they bought the car with 32k and have taken care of it. Basically no rust, not one bolt fought me not even the motor mount to frame anchor points. sad to see it go the ways, the guy ended up backing out after i totaled up the grand cost to get ahold of a 3.2 and put it in. Not many of those 3.2's around anymore...


Btw wasn't there a pushrod 2200?? i feel like i remember working on one...

 

[Fox80]

Yea all of the first gen. 4cyl motors were in block cam motors, they still are around in boats, I have a 2004 Bayliner that has an all iron pushrod GM 4cyl in it. Good call on the Chrysler some cars are just not worth fixing, of course I have that opinion about most Chrysler products
