My 67 GTO has the original 400, which was rebuilt and using the original valve covers, with a breather on each, and the PCV valve in the valley pan. Having had 60 cars, I never once paid any attention to the PCV system. I never knew what it was for, never really cared, and I was like most of...
Using Ultra Grey on the VC side of my VC cork gaskets, I was able to stop my leaks, until the PCV issues overruled it. I've since fixed the PCV and switched to Edelbrock Pontiac Gaskets. They're super thick and much tougher than cork.
Thanks a lot, I hope, I'll find something equal in germany or amazon.
I also have these aluminium valve covers with the PONTIAC letters on top.
Which gasket is needed or will be the best for these covers ? rubber ?
One more question:
My new chromed valve covers (the same like the painted old ones I drove the last years) have a 1" diameter hole, the other cover have the bayonet lock for the breather/oil filler cap.
The left cover hole was/is covered with a (pastic or maybe a hard rubber-) plug, the driver side is with the breather cap.
Where can I get such a closed plug for the 1" diameter hole ?
What was stock equiped ?
with cork gaskets I don't use any sealant on my valve covers. they soak up oil as your drive and "seal" themselves. works good for me, just dont over torque and as Army says, PCV system has gotta be sorted.
So I have glued the cork seal into the covers (because the seal was not exacty in form, so it will not stay in place....)
This is also the cover with the 1" diameter hole, where I need a plug (without hole). regards: Peter
