Ok, I am 90% sure I have excessive blowby. It leaks oil from every gasket and seal top to bottom of the engine. You can feel it when opening the oil fill cap and I'm loosing about a half a quart every 500 miles now. I don't think I'm burning much.
What can I do to test and figure this out. This is supposedly a new engine but had some cold starts after it sat for 3-4 years. The performance seems really good, pcv valve is fine, has plenty of power and doesn't smoke. I'll do a compression test and maybe get a boroscope to look at the cylinder walls but other than tearing it down to see if my piston oil rings are stuck I don't know.
Edit. One positive note the car has had no additional rust this winter because of the new coat of oil on the underbody everyone I drive.
