My recently transplanted 3.2 engine.....
Fitted, and running sweet. But I noticed some oil on the bellhousing at the bottom, and let it idle for half hour, you get a nice little puddle on the floor.
Also, there appears to be oil collecting on the top sump directly under the crank pulley.
I have taken the Cambelt cover off today to look at this, and I noticed that ALL of the camshaft oil seals (Gen GM, just replaced) have a misting of oil around them. Whilst I can't see the crank seal, I believe there is some oil coming from this, as there is a fair bit of oil under the sprocket, with no evidence of any having ran down the engine.
The valley has been exposed, and there are no leaks from the oil cooler unions.
The breathers are squeaky clear.
I can't help but think there might be an oil pressure problem.... I don't buy it that these seals just fail. Can the oil pressure relief valve stick, and cause too much pressure?
In fact thinking of that... when I got the engine home and had a look, the cam covers had silicone all around them - despite the gaskets being new and GM... so I wonder if someone had been battling with ongoing leaks, prior to me having the block....
I'm not sure if it's related, I also have some lifter noise from the passenger bank, which does go away when the car is fully up to temp. It sounds like just one lifter, not oil starvation or anything nasty.
I don't even know what the oil pressure is supposed to be... could anyone give me any pointers on this please?
I don't want to start ripping off the gearbox and changing the crank seals etc if the new ones are going to fail straight away!
