I have a 2003 acura cl type s 6 speed with a fully rebuilt motor. Engine compression shows over 300 psi per cylinder. Car does not show any signs of smoke from tail pipe. Upper intake manifold was cleaned, but now the inside of the intake is completely covered in oil. Piston rings and valve guides/seals are new. Has no oil leaks. Uses 1 quart per 350 miles.

 

Hmmm, what kind of shape is the PCV in?

 

I already have a new PCV valve installed.
