    A Special Note about Email accounts!
    DO NOT SIGN UP USING hotmail, outlook, gmx, sbcglobal, att, bellsouth or email.com. They delete our forum signup emails.

    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

How have you guys unstuck piston rings?

I have two pistons that are unworn and still have the hone marks on the cylinders and the machining on the piston but the rings have fallen in love with their groove.

permanent magnets? Pb plaster helped some but im um STUCK
 
I've heard MMO, SeaFoam, or ATF. Or all three -- can't hurt.
 
Those rings are done for anyway, I wouldn't trust their "springiness" after I freed them up. If they are already out of the engine, drop the whole works into ATF or diesel or some form of dip, and then let them sit for a while, maybe days once the rings seem loose enough to get out an end break 'em out and get a new set.
