    Has anyone ever had this done to their engine? Its done with a hydrogen powered decarbonizing machine. My car basically sat for 3 years before I purchased it. We found that their is lots of carbon buildup on the piston heads. One cylinder had low compression and a 70% leak down. Either the valve is damaged or the valve is not seating properly. I think most of you experts would bet on a valve guide problem or valve itself. No damage on the top of the piston. Im know expert but just wanting expert opinions. Thanks

    355 huh? So possible carbon on valve seats preventing sealing your thinking, or possible stuck rings?
    Never done what your saying but I have done sea foam. BG EPR seems to have positive reviews as well.
    Cheap and worth a try use 1/3 to1/2 tank of fuel not a full tank.

    Best of luck and possibly a cheap fix :)

    Steam is the easiest way to clean it. Open the intake and, using a spray bottle, squirt water into the intake. Just don't go crazy with this since you can lean out the motor.

    Then there is the method of burning it out.
