Head Gasket Maybe?

[1slowdsm]

I have a cracked valve cover, would that contribute to any smoke at all? I'm hoping I'm blowing black smoke under boost, its safer and better than that blue smoke. My car sometimes blow out smoke that smells really weird, but I'm guessing its from the straight pipe. I dont know though, I could be wrong.

Alright I've figured out it's probably not a head gasket.

The smoke is blue and it comes out in huge puffs whenever I boost. This morning when the car was cold and I started driving it I had no boost at all and there was no smoke at all, but once it warmed up I had full and it started smoking again. It did the same thing when I left work. Also two bolts to my exhaust manifold are broken and not connected, which hasn't been a problem. But there is oil around where the mani connects to the head.

Any ideas?
