I noticed that I have an oil leak on the driver side, which appears to be coming from the valve cover gasket. Its only at the back part, and it leaked slighty down onto the back 3 header bolts and on the top of the header gasket. I've been having some white smoke thats been coming out after I get on it, and I'm wondering if this could be causing it. Also, is the valve cover gasket the only part that would cause oil to leak down onto the header flange and gasket? I've replaced the gasket on my old lt1, is it the same process on an ls1? Thanks in advance.

 

Anyone?
