Engine's smoking After my engine has been running for a few minutes, it will start smoking from what appears to be the passenger side heads. The smoke is gray and has no noticable odor. Not quite sure what it would be.

Well i'll try to take a video when i have time. But here is what is happening to the best of what I can describe. I start the engine, after about a minute a gray smoke with little odor to it seems to be coming from somewhere on the passenger side of the engine. It seems like it might be coming from under the valve cover, and there is quite a bit of it.
i may be wrong but mine was doing the same thing i couldnt figure it out for the life of me, then one day i turned my wheel and i heard the ever so famous powersteering whine, so i looked real closely and the hose had a small leak, it leaked long enough that it caused my alternator to go bad but when it idled for a second it would smoke so u may want to check that just imo

Here is a video of where it was coming from, you can't see the smoke very well but it is noticable. http://s99.photobucket.com/albums/l2...t=MOV00590.flv
It smokes for a good bit after the engine is turned off as well.

Hmm, can anyone else agree or disagree with this. Hopefully this is all it is as I'm going to be getting some work done on it in next few weeks that is the only problem. What makes it smoke so long after the engine's off?

what makes it smoke is there is still oil on the manifold. The reason the old small blocks are so bad, is because the oil drain back holes are not big enough to drain the oil out of the rocker area. Plus the sealing surface of the head sucks and only has four perimeter bolts to hold the cover down. When GM switched to the centerbolt valvecover in 86-87? most of the valve cover gasket problems quit. They also put a lip on the inside of the valve cover to keep oil from directly hitting the gasket. I would recommend the fel-pro rubber gasket. Those are the ones I have had the best luck with.
