Hellraiser is looking for answers did a leak down and a compression test on my motor because someone said I have a #3 cylinder low and out of spec.
leak down test and compression test
#1 100/90 cold 100/90 hot 190 psi cold
#2 100/88 cold 100/92 hot 200 psi cold
#3 100/88 cold 100/85 hot 200 psi cold
#4 100/83 cold 100/85 hot 200 psi cold
#5 100/87 cold 100/86 hot 200 psi cold
#6 100/88 cold 100/86 hot 200 psi cold
#7 100/85 cold 100/84 hot 200 psi cold
#8 100/87 cold 100/86 hot 200 psi cold
when the motor temp was hot I could hear air puching out of the air intake on every cylinder leak down test. this is a 440 built for dope ring gaps .024/.029 thanks for the help. Is there other things I could check!

might need to put it back the way that it was and try that. I don't think that was checked. Ill ask when I talk to them monday! why would I hear more air push back when valves were closed when hot on the intake side? Did not hear it when the motor was cold

just did another leak down after reading on the net. The leak down tester I have said to do it with the piston at the bottom of the cylinder and that's where the first numbers came from. After reading and talking to others I was told to check it a TDC at run temp. I did this and here are the new numbers? What do you think?

I need to get the slave cylinder fixed. If there is a problem with the motor no need in fixing the slave cylinder if the motor needs to come out. I was going to drop her off at the shop Friday but got called out to work! Maybe I can get her there this Friday!
Get that hooptie running.
