Looking for a gasket, or is it an o-ring. It goes between the PCV adaptor and engine block, mounted behind the intake manifold.

Any ideas.

I found it in the AIM and its part number 3855582.

I took my intake off yesterday to install new intake manifold gaskets to fix vacuum leak. I took off the PCV adaptor and found that it did not have a gasket, it had been put in with silicone, but there was oil everywhere, not sure what was leaking. I want to seal everything good when I put it back together.

Thanks,

Roger
