    It could def be an issue with any of the 4 valves in the head and/or something in regards to the pistons/rings.

    I'm assuming the car ran funny and that's why you did the comp test.

    How was it running? Loud knocking? Tapping sound from the head area?

    You can do a leak-down test to also pin-point where it's comming from do you have the means to do so?

    If not we can take care of that and further diagnose the issue at the shop.

    Feel free to pm me or Mike B @ FFTEC or give him a call today 510-475-5855

    if your mech was worth a shit he'd have a cyl leakage tester and you could pinpoint the compression loss
