I have an exhaust leak from the manifold because it was missing two bolts and it burned the gasket and my question was is it hard to replace the gasket?

 

Nope. Just pull the bolts out and slap a new one on. You sure you have to repace it? Mine had same prob once apon a time and I just threw a bolt in and tightened her up and leak went away.

 

Yeah bro because on the valve cover on the side by the cab der is lik black stuff i think carbon from the exhaust that is leaking from the top and plus ill just buy new bolts and new gasket
