My 97 lt1 camero is leaking and spraying oil out of the Smog system connected to the passenger side exhaust manifold. This is creating an ungodly amount of smoke when i drive. Ive tried investigating the pcv valves and vac system, as they could contribute to high crankcase preassure there for feeding oil into the smog system, but am not finding any good leads to fix this problem, any suggestions?
