I don't have a PCV system so the only place the oil can come from is the gasket area between the heads and the intake. This is confirmed by taking off the intake and checking my gasket. Totally soaked with the runner and head port soaked at the bottom with the top dry.

How do you seal it better? I was thinking the standard gasket (graphite coated metal) along with a bead just below the gasket on the underside of the ports.

Any ideas?

Thanks.

 

Have the heads been milled. If so, there may be a mismatch between the heads and intake. If not, are you sure the intake was torqued correctly?

 

Mismatch corrected last time with issues still. Yes intake correctly torqued to 35, 15 at a time in the order required.
