Time to rebuild?

Those leak downs would worry me and so would the compression #'s.
Good news is a Ring, Bearing, and gasket rebuild is gonna be easy on the wallet.
One more point I can speak on. My son went to College recently. If you can beg, bribe, or order him to work with you on it, DO IT.
Spend the time with him while you can.
Oh yeah another thing..
DO IT, DO IT, DO IT.
Time will come when he is not around.
Sorry to be a downer. Living it now. One of the worst feelings I have had is coming home to remember that he is not in the house any more......
