need to figure out how to do a leak down test????

[CUL8RV8]

i was hoping someone can tell me exactly how to do a leak down test. ive looked around but no one really describes how to do it. first off i had 150 across the board in compression except for 2nd piston which had 135. my car has been overheating lately so i put oil in the 1st piston and it jumped to 150. so i know its not my piston rings. now one thing i should put out that my car one day didnt seem to run right so i check my spark plugs and had water all over the spark plug so immediately i think its a headgasket problem. again at this point i think doing a leak down test is my easiest way of finding out exactly what is wrong. thanks guys its nice to know we have a forum to helps us out in our depressed days of dsm land. !

This should help. http://www.xs11.com/tips/misc/misc3.shtml However, I'd suggest allowing a qualfied shop to do the leak down or at the least buy a "real" leak down tester.
