ALtima intake manifold R&R procedure?
 

Hi,

My daughter's '01 Altima needs the intake manifold gasket replaced. I understand it's a fair bit of work. I'm up to tackling it, have the tools, etc, but would really like a step-by-step procedure. The manual had nothing but a useless exploded diagram. Is there a procedure posted somewhere, or do I just have to dive in? (I really don't want to do that!)

Thanks!
