help please

Regarding item 1:

Where is the leak exactly. Taking off the crank and the oil pump requires dropping the whole bottom end of the engine. It's quite a bit of work. Be sure you have pinpointed the leak.

Regarding item 2:
It sounds like your troubles with heat/air might be due to a malfunctioning heat slider. The mechanics of how these work is detailed in the service manual which can be downloaded from the manuals section. You may also find the following thread helpful:

Do you agree that your slider might be to blame?
