I've been trying to track down this problem for months but it keeps getting worse. After only 100 miles all the plugs are drenched in oil. There is no perceivable blo by. The valve seals are new and I believe the intake is not leaking but I haven't taken it off to check. So what else can it be? Someone said valve guides but they seemed ok when I changed the seals so what else is there? Please help. Thanks in advance. BTW I'm talking about the red 383 supercharged camaro in my sig.

Does the SC in your sig mean supercharged? If so the pvc system may need a one way check valve to keep the blower from pressurizing the pan.

 

Hmm, I hadn't thought of that. I don't think it applies since I'm running a breather instead of a PCV system.

 

are the heads totally stock, or ported or aftermarket?

 

Any oil coming out of the breather yet?
It is still possible to get enough pressure to override the oil ring.

 

Heavily ported (300 cfm) stock heads.

 

There is a bit of oil on the bottom of breather but I believe it's just spashing off the rockers.

 

on ported or aftermarket heads, the intake rocker stud holes will open into the intake ports, and if they are not sealed, they will allow oil to be sucked into the intake ports, and into the cylinders

 

That sounds like the problem. So how do I fix it? What is the best way to seal it?

 

pull the valve covers, remove the rockers, and remove every intake stud, clean the threads(stud and in the head) and seal, most seem to use RTV on the threads(apply to the threads of the stud) torque the stud back down to 50 lb/ft


you might want to inspect the exhaust stud holes as well, make sure they are not through to anything

 

I was told Mike Blackstone heads don't have this problem and inspection seemed to prove that. Here is what I found:

I took off the throttle body and discovered oil on the back of it
and on the gasket (both sides). TB bolts were loose which could
explain high and irregular idle. There are two holes on the inside of
the intake close to where the TB mounts. These holes are very black.
It seems oil may be coming up from there. The intake is very black
inside except where the runners are. With a mirror I could see far
down and it looked clean as far as I could see down the runners. So
what does it all mean?

I'm not sure if you can see these pics but here is a link:

Anybody know what I should do???
