    Sounds like you may have an intake valve not closing.

    Understand but us that run shops and that the leak down tester can do a non-invasive test to determine if the valves are closing sealing as they should. We only need to pull the spark plug on each cylinder and that cylinder to TDC or a little pass compression as we test.

    Unfortunately there are no shops or individuals near me that i can find that would work on the engine or i would be more than happy to have an expert check it out - i tried even calling dealers (john dear) but they said they would not work on an older engine.
