Intake Leaking Oil

Thanks for all the responses guys.
The oil is being sucked through the bottom of the intake port. You can see it when I took it apart.
I tried Edelbrock Gasketsinch, Indianhead sealer,even 3M weatherstrip adhesive.
The roll pins do not bottom out, the manifold sits down flat on the china wall without any gaskets.
The intake was milled .015 last summer so it's flat.
I used 6 different gasket sets last year. The ones that lasted longest were the ones I made myself. Not using the end gaskets, just RTV.
It has a functioning PCV valve.
I used teflon sealer paste on the intake bolts.
I did not try the Right Stuff sealer. Will have to look into that.
The head sealing surface is really smooth. When I had the chamber surface milled, it was made smooth enough for a MLS head gasket. The head's intake surface was milled at the same time. I could look into ruffing up that surface.
I tried .060 thick gaskets and .030 thick. The .030 lasted about 200 miles before it failed.
Maybe a thicker softer gasket?
Thanks and Happy Easter!
