Oil in intake manifold

[Stang 23]

I'm getting a lot of oil or blow by into my intake manifold. The shop I have it at right now was going to do a compression test and radiator pressure test. There seeing if it possibly blew a head gasket. What do you guys think it could be?

Are you running the stock closed pcv system?

Head gasket would be coolant not oil. Compression test is a good idea.

Ya it's the stock system

PCV.

Got a filter between the intake and driver-side valve cover? That short hose is blowing oil into the intake.

PCV.

+1 Install a catch can setup. I had alot of oil when swapping manifolds, installed a catch can and problem solved.

PCV.

This.

I changed to clear hose when I was installing catch can and when engine is running you can literally see oil moving thru

Ya I just bought a catch can. so hopefully this will help a lot. It could also be a bad PCV check valve?
