Hey everyone, my first post and annoyingly its bad.
I bought a very cheap 300c 5.7 that i knew had engine issues, but trying to diagnose it.
Basically the engine is sucking huge amounts of air from the crankcase, but not through the PCV. When you rev it, massive clouds of grey smoke come out and the oil filler and dipstick tube are sucking air in.
Never seen anything like it before. Is it possible that the intake could be pulling vacuum through the oil gallery gaskets that go to the oil filler and crank vents?
Or maybe something far more catastrophic? It has me stumped other than maybe taking the intake off and inspecting the gaskets and whatnot.
Any suggestions appreciated.
