2003 trailblazer valve cover gasket repair made more easily. 

This is great. Thank you!!!

Interesting Short cut.

I am about to do mine tonight. It’s leaking oil to the plugs. So I don’t have to remove the whole intake manifold? Just loosen it? What about the alternator and gas line?

How much easier is it taking the wheel off? If I don't, how do i get to those lower bolts? I'm a chic doing it by myself;)

It can be done if you have mechanical skills and common sense,,if you a beginner may want to go by the book
