Post by misterhoang »

Hey Guys,
I noticed an oil leak from my oil sump, I just wanted to know if its just a gasket to replace there? or do i just apply a sealant around it?

Hmmm- you too......

No gasket on sump, silicone inserts over bearing caps not crazy about the whole system but if mine wasn't leaking I might think differently.

Leak from the distributor drive is pretty common as well and looks very similar from the underneath so check first.

Could be rear main of course - but neither of us want to consider that option. :cry:

It seemed like a much better idea when I started it than it does now.

if it is leaking from the distributor drive, whats the prognosis on that;?
and for the leak from the main rear, what do you mean by that ?

I just recently replaced the rear main seal, but the leak is still there =[, you guys think it could be something else that looks like a rear main seal? or do you think chances are I screwed up while i was replacing the new rear main seal ?

Did you check the seal surface of the crankshaft when you were replacing the seal ? If its scored then its just going to keep chewing out seals. Sometimes you can leave the seal hanging out - or press it in further so it runs on a non worn bit of the crank....

But as posted earlier the rubber insert that straddles the rear main is also a very average design - so it could also be that. Lots of silicone is the answer.

Whilst I haven't tried it, if you drop the front diff you should be able to pull the sump with the engine in the car and reseal the sump and inserts... but that's a guess not a fact so don't hold me to it......
