Rear engine gasket leaking?

[Florian]

Hi!

I didn´t know wether I should post this in the engine or in the drivetrain section because it´s actually really in the middle of the two

I noticed a small oil stain under my truck today:




The transmission is oily:




Is this the gasket between the engine and the transmission that is causing this? It´s engine oil btw, no red tranny oil.

Thanks,

Florian

There is no gasket between the engine and transmission.

It's probably either valve cover gaskets or the rear intake manifold seal leaking.

I didn´t know this, thanks!

Haha I gotta remember this one next time one of my neighbors complains about oil stains on the street

Looks like a leaking rear main oil seal to me Florian.

i would check the rear intake first before you tackle the rear main seal.

This is a good idea. Sometimes oil from the intake will run down and make you think it is the rear main leaking.

Damn, I hope it isn´t the rear main seal...

I'd rather replace a rear main seal than lift that lead weight off the top of my engine!!!

I guess it´s the driver´s side valve cover gasket. It´s quite oily up there, but can´t really say because I need to charge my battery before I can fire it up. The oil that is there looks old. Hasn´t been running for 3 to 4 weeks now.

It´s also very oily in the front because there was some problem with the oil pressure gauge told me the previous owner:
