Bill, Are you sure the noise is coming from under the cam cover? Reason I ask is, Jim Voter had an issue with his 90 a while back and it turned out to to be a crack in the air tubes on the stock exhaust manifold. It sounded like a ticking noise too but after Mark H. started feeling around, found the cracked air tube. Something worth checking. I have always used 10W-40 in my Z, 5W-30 seems a bit light for me. JMHO.
