I,m thinking PCV valve also. Some of the aftermarket valve covers don,t have shields around the vent holes. Pull the pcv valve out & see if there is oil in the hose. You have to have 2 sorses of vents. The pcv plus a vent cap or tube going to the air filter.

They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
