I think my oil pump broke...hope motor is ok

[wingman65]

New member here, long time GP owner. My 95 SE 3100 won't turn over now. Driving home from work, oil light came on and engine started running rough, then stalled. I got it to start and nursed it off road onto parking lot but it was really running rough and then died. Towed it home, now it wont turn over

Anyone have any ideas. I hope it isnt fatal.

Once the oil light comes on you're done generally.

you probably spun a bearing. my bet is that it wont start and if it does it knocks at idle.

uh oh..... im affraid of my engine...

how many miles do you have on it?

[wingman65]

140k and ran great til yesterday. I just replaced the lower intake gasket a couple of months ago and that fixed my leaks. Should I attempt replacing the crank, bearings and oil pump or should I plan on a motor replacement. Money is tight but I cannot go without a car or buy a new one.

if you take apart the bottom end you need to get things machined. easiest thing to do is to drop in a new block.

Is it possible to pull the motor while leaving transaxle in place?

[brandonl2000]

veyr possible. on my 97-03 (assuming they are similar enough) you just take out the bell housing bolts and flywheel /torque converter bolts and the engine comes out.

Update to my motors health. It has a broken cam, bent valve, and a spun rod bearing that had welded itself to the crank. The motor was locked up tight, making it difficult to get to torque converter bolts. I wound up pulling it away from trans about an inch and getting to the bolts with a long, thin 18mm wrench.


Bought a used 3100 from "flea bay" believe it or not for $700 delivered. Went through it giving it a very thorough inspection, replacing all the gaskets and cleaning it inside and out. No sighns of sludge, very clean on inside.


Today I got it bolted back into car along with a new solid rubber lower mount. I need to reinstall accessories and electronics and all will be golden. Thanks a bunch to all on this forum for the vast collection of information, It was priceless.
