  • low compression after H/G swap

    http://forum.camarov6.com/showthread.php?t=66426
    is my original thread.
    It was working fine, then died on me.
    My compression #s:
    6-80..............5-100
    4-95..............3-93
    2-100............1-80psi

    Shouldnt my compression be like 120-125psi?
    I didnt use anything on the head gaskets...just torqued the bolts down
    Maybe I blew both head gaskets from high AFRs?

    im guessing thats non running comression? from those reading, you have a dead cylinder in all cylinders. you need to do a cylinder leakage test and find out were all of it is going.

      thats with all of the sparks out. where can I get a leakage tester?

        how can you find "running compression"? is that possible?

          running compression is the car running with only that cylinder plug out and the tester in. As far as the tool, I would look at sears or any other tool stores like harbor freight and such. fairly cheap if you buy a cheap brand.

            i didnt use copper spray. I just used the fel-pro gaskets straight with new head bolts. Maybe I overtorqued/undertorqued?

              there really is no telling what has happened. it could be almost anything. just get your hands on that tool. i bet you could evenr rent it for free from autozone or O'Reillys

                Re: low compression after H/G swap

                I dont really know but I dont think a leak down tester is gonna find my problem for me. I think the best thing would be to just redo the head gasket swap for the 3rd time now.
                This time use copper spray, and get a professional torque wrench.
                I have a clicker torque wrench and a dial. I really dont know....

                  i tried to tap/die the bolt threads.
                  I need to try something like acetone to clean them out or something

                    are ARP head bolts reuseable? They are $135. I would rather it be a stronger metal than chromemoly. Chromemoly is lightweight but strong. I'd just rather put chromemoly somewhere else... like the drivetrain/powertrain

                      Damn dude I woudl rather blow the $15 on the tool and check it right then pulle the heads and replace the headgaskets again.

                        Are the readings after having the heads seal ?starting the motor letting it run for a couple minutes then letting it cool . thr head gaskets dont make a perfect seal till this happens .

                          Re: low compression after H/G swap

                          yes, i've run the engine after the swap. Then I ran it again and it died on me, now I cant start it at all and my compression on each cylinder is 80-100psi!
                          I dont really see how a gauge is gonna tell me anything special. It will tell me only what I already know: low compression.

                              I just realized that I had my throttle body closed, so that might affect my compression reading. i'm a tard
