so ive been having hot and cold start issues including white smoke from the exauhst and a very minnor coolant lose. i just did a bubble test because i was almost sure it was a seal. but the only time i saw a bubble was when i gave it some gas and the t sat opened up there where like 3 big bubble then it was clam again. i let it idle for about 20min and no bubbles. then i shut her down and i noticed 2 more bubbles escape a few minutes later. what else could be causing this? i tried to take out the leading plug to see if i had fluid in the housing but i didnt see any. what i did notice was a very brown/black plug like its running rich?

i need a little help.

 

those few bubbles could be the loss that you are having. if you can i would let the car sit over night and then check then pull the spark plug and chk. if you have a
12A it very well could be the 2 orings between the intake manifold and the block. when you say very minor coolant loss how much, is it a cup of coolant a week?
when was the last time you changed your plugs and if you go to the top of the 1st gen page there are the FAQ's that will help
