fasterhatch

i have a 93 hatch with a B16A2 swap and i recently noticed oil spots on the ground and i noticed the head gasket was leaking, i dont think it is blown because it runs and idles fine. i havent been driving it at all because im going to take out the motor out with a friend to clean it up, but i cant replace a head gasket myself mainly because i dont trust myself with cams and valve timing, I'll just pay someone else to do it. anyways, i looked again just now and saw oil leaking from the distributor! and when i turned the car off i saw ******* small BUBBLES coming up from where the tranny meets the block! If the cars turns on and runs fine, does that mean that the distributor is good? Why are there small bubbles coming from the tranny/block? Could the "O" ring be bad in the distributor? ---------------HELP-------------------
