    I notice some smoke coming off of the manifold , and though it might be a broken gasket, but even after i replaced it there is still smoke coming out. This Video should help to show. any ideas on what this might be?

    It is probaly getting oil on it from somewhere. It doesn't take but just a little bit to cause the smoke

    Some of the exhaust studs go into a water jacket. Found that out last year when I remove one to test fit a set of headers. I had coolant everywhere, but that explained why I had coolant running down my exhaust. The smoke could be steam if coolant is leaking around that stud.

    This was the old gasket that i pulled off, one side has more oil on it then the other, granted that side is right below where i fill up with oil, just worried it might be oil getting burned up inside.Exhaust manifold smoke Xsp77e_vid-20120808-151904_auto[img]Exhaust manifold smoke Img_2012[/img]

    by the look of that gasket you have either changed heads or engines. the exhaust manifold looks like an original, for a newer style engine, and if it is there are small holes in the cylinder head that are for emissions stuff you don't need or use. slip your manifolds off and check for the holes just below the exhaust ports. if they are there tap them and install a set screw with some locktite on the threads. the newer gaskets might not have the provision to cover the holes and its a direct exhaust leak. either that or the manifold is warped and won't tighten, check it with a straight edge when its off lookin for the emission holes.
