    Default Pistons

    I am going to do a compression test on my Signum soon as I may have worn piston rings.
    Does anyone know where to buy aftermarket Pistons so I can compare prices if I go down this route?
    Is there anything else that should be changed if I were to do this (headgasket for example, rebore engine etc.)?
    My Signum has done 134,000 miles. If it turns out to be an engine rebuild/refurb what does this involve?
    What price would this be on average and what would be done?
    Thanks

    Do the compression test on each cylinder, then squirt some oil into the bores and test again. If the readings go up significantly then its bores/rings.
