I was getting ready to run my 72 down the strip today but noted a faint blue tinged smoke coming from the left exhaust pipe as I was getting ready to leave. Anyway, I pulled all the plugs on that side and found the plug on cylinder 2 to be really oily.(almost fouled) I pulled all the other plugs and they all looked fine. The engine is a 290hp GM crate engine about 2 years old with maybe 3000miles on it. Any ideas as to what is going on? Think it could be a valve seal? This engine was properly broken in and not beat on so I am at a loss as to what is going on.
