This weekend I am going to remove my upper intake manifold because I think I hear a sucking sound (air leak) and my vacumm at idle has dropped a few inches. The only vac lines I have not replaced are the ones (if any) under the upper intake manifold. Im ging to replace coolant lines and vac lines while I have it off. SHould I replace anything else?

I am just not sure what to expect when I take this thing off. Should I remove some coolant first so coolant doesnt unexpectantly dump into the intake?? I am not going to buy any gaskets but I do have a roll of that make your own gasket stuff and a tube or permatex.

I am going to investigate injector wiring, PD, and injectors but I do not plan on taking anything off the rails, but I may replace all the fuel lines from the tank to the front of my car since they are old and under a lot more pressure. I really dont know.

I want to investigate my oil injectors. Can I remove them and possibly clean them up and reuse them? Are they delicate?

All for an intake leak!! I love preventative maintenence.

A five sentence walk-through from somebody would make me very happy.
