Xfire finally out of storage after a 5yr hiatus (yikes), and after doing a bunch of maintenance and getting the car smogged (ugh) I noticed I was leakin' a bit of oil out of the block. It's right below the oil fill cap. I sifted through a bunch of "oil leak" posts on the forum, but I didn't see much.

Anyone have an idea what this could be? I have to rip the manifolds back off to install new gaskets and I thought I'd address the problem at the same time. Pic attached.

Thanks and glad to be back

 

Vent cover re-sealing and possibly lower oil fill gasket.

 

Plus 1 on the vent cover leak.

Yep, looks like it. Thanks for the PDF link, got myself a DIY for next weekend.

 

AND, pay close attention to the torque on those screws. If I am not mistaken, they may need to be replaced. If not, make sure you do not 'overtorque' them (very low setting in the inch pounds).

Super helpful and exactly what I needed! Thanks.

I'll make sure to replace the bolts also. After I buy a digital torque wrench. Been wanting one of those anyway.

 

The torque setting for the aluminum screws in the breather covers is 4 N.m = 35.4 in-lb = 2.95 ft-lb.
The torque setting for the steel screws on the valve covers is 8 N.m = 71 in-lb = 6.0 ft-lb (7 ft-lb in our Service Manual).
