I just read c-speedracing's how-to on a leak down test.

my new build's initial compression test was a little disappointing. i will do the compression again for the next few days but if numbers don't improve, then perhaps I have bad valves.

where can i buy my own leak down test kit? i searched sears and several auto stores with no luck. please help!

thanks

 

Snap-ON sells them....thats where I picked up mine. I just called some local repair shops for the local snap-on guy's phone number.

 

damn - i just went to snap-on.com and found a cylinder leakage tester for $299!!!!

c-speedracing says they can be had for 60ish. anywehre else??

 

well i may not need the leakage tester just yet. i put 50 miles on it saturday and checked compression sunday morning. all cylinders were 190-200ish. today i checked after work before heading home and they were all around 220.

i'm going to put some more miles on her and check compression each day after work. as soon as the readings level off, the rings should be seated.

 

Definetly put some miles on it, then test it.
