+1 Sideways.
It seems to be a pretty common problem. I have changed mine too. So Tortuga I hope you get lucky!! What does the
oil look like???
I am using a Victor Jr intake. Motor sucked in the gasket from the top side of the engine on deceleration from high rpms. So when I replaced the gaskets I put a bead of the Right Stuff on the top side of the gaskets after I torqued the intake.
Knock on wood, no recurring problem
