Chrysler 2.7l

Anybody have experience with these engines? I just finished pulling one and i'm opening it up tomorrow to see what failed. It's either a rod or main bearing. I've been told these engines are known for this, the oil light would intermediately come on before it started knocking. I guess the rear most main bearing can spin and block off an oil passage.

The guy wants to rebuild the engine, cant talk him out of it.

depends on which version it is.... the earlier versions had issues with the internal water pump (behind the timing cover) gasket failing and putting coolant into the oil and you wouldn't know until it was too late... sludging up the whole works.

If I can't talk someone out of a bad idea I charge them out of it. These are an engine with a pretty poor reputation on their own. If anything, try to sway him toward a replacement rebuilt longblock as opposed to rebuilding the one he has. At least if something goes sideways YOU weren't the one who built it.

Like the above post said these motors have many design issues, I have done several water pump jobs, two head gasket jobs. If you choose to do it this I can tell you I had two aftermarket timing chains be marked wrong, only use OEM. They use this stupid paint dot system and the aftermarket one must have been off a bit, car ran but at a slight shake at idle and I knew it wasn't right. These motors have very, very small passages feeding the cams you have to clean everything very well and mic every cam journal and lobe, if you have the heads resurfaced pull all the valves and torque the cams in before you do it, or your cam journals are not aligned when the head is on, you may also have to cut all the caps and line bore the cam journal. I only used OEM water pumps as well, heard horror stories about the aftermarket ones, it is very expensive to rebuild one of these motors and if not done exactly right it will fail, would have to weigh it and decide if the car is worth it

GP403 & Fox80, earlier version? It's a 2000 so it must be. I'll check and see if sludge was the indirect/direct reason for failure, and if so i'll just tell him outright he needs a new engine. The timing chain setup sounds similar to a GM 2.2l, i try to use OEM for timing components on newer stuff regardless. I've been quoted 3400$ for a remaned long block, and nobody in the area has a good used engine. The best i found was one for $1350, with 86k millage. I've checked every salvage yard..ext, it is what it is for this area.


DRIVEN, he's an inlaw and i feel bad. He asked me to do this and understands it could end up failing again because the engine was just bad by design. However i didn't know the rest of this, i just thought they had rod end problems. Rest of the car really is in immaculate condition and they just bought it.

I did some some research last night after i posted this, i think i'm just going to look for a 3.2/3.5 to swap in for him, much better engine and it's not hard to do. If i go this route, can i flash the ECM or do i have to replace?

I just remember reading nothing but horror stories about the 2.7 when I was researching buying my Magnum. That was '04... so.

My buddy's dad had a 2.7 in a 300c. Timing chain went on it. I hate chrysler in general. They all look nice, yet they run like sh*t.

Seems like a lot of work but apparently it's doable.

Wow. Want to know whats most shocking? I phoned a local Chrysler dealership where a friend works, from tech to tech he told me to 'just put new bearings in it and send them on there way". I bet that guy gets paid more than me.

You can try it. I prefer when they don't come back.
