Default Re: oil leak on 305E exhaust manifold

GMCNut:
Question would be why the No. 1 cylinder is throwing that much oil out of the exhaust? What other symptoms are you having? Is exhaust pipe putting out a blue smoke screen? What does the spark plug from that cylinder look like? Have you tried a compression test on that cylinder? Have you checked the valve lash on that cylinder? Hopefully those questions help. What you see is out of the ordinary. I think you need to do some more fact finding to decide what is causing it.
