Did the vinegar trick and between it and having new heads placed on, due to a dropped valve seat, it no longer knocks.

The vinegar definitely works though, when I drained it, it looked like I was draining a septic tank.

Glad you found the problem. Vinegar made my $30.00 super cool with a $10.00 pressure test look like a freshly roded radiator. Love the stuff.

I know this is an old thread and the problem as been solved but I just came across it while searching for something else.
