did a leak down test and got a huge differance in percentage #1 cylinder was 77%#2at75%3at4% 5at3% all readings were with piston at tdc.only had 30 psi to test with i know 40 psi will work even with lower pressuer i would think i have head or piston problems.let me know if anyone thinks i may have missed something.

 

where is the air going? Coolant bubbles? Sounds like the head gasket failed between cylinder 1 and 2.

 

realy could not tell where the air was going i can say no bubbles in the coolant no air out of blow by tube or dip stick it just sounded like it was leaking near the adapter/test fitting.the odd thing was that it ran smooth until the temp got to 200* then as soon as you would give it a little hard throttle it would bring on a dead miss.if you need just simple yes or no questions to figure it out i would be glad to do so.this may be a forgone conclusion cause i will pull the heads in a few days and will tell all.Isure hope your right about the head gasket trust me.
