And now I have fixed the air leak out of metal pipe and now I noticed new oil on the engine under the distributor cap could that be part of the head gasket and if it is than obviously I would have to replace it, but what els would I need to take off and is there more gaskets I would have to replace?

The first thing to resolve is to get all the leaks fixed and air pockets out of the cooling system and that may not be easy. Pressure test the cooling system to determine if you have any leaks. Once you confirm all the leaks are fixed, then I would have the system vacuum filled to remove all the air. At this point I wouldn't be surprised if the previous overheating hasn't caused internal damage like a blown head gasket.

If the water pump is bad how would that affect the pressure or would it

The water pump has nothing to do with pressure. It merely circulates.
If it's leaking that has to be repaired.

You probably finally got all the air out of the system. If it shows up again after a period of time, that would point to a head gasket problem.
