Fubared........ again.............ahhhhhhhhhhhhhhhhhhhhhh. For those unfamiliar with the saga. I'm in the middle of a TBI upgrade and I had an engine knock in a 2 year old crate motor I wanted to address while I was at it. Got the worst possible news. Number 6 piston keeper was either installed improperly or junk from the rebuilder. There is an unflattering 1/4 deep groove in the cylinder wall on either side of my piston. Piston itself is roasty toast. I sit and shake my head. Somebody remind me what it was I found appealing in fixing up old trucks and emptying my wallet in the dirt. Maybe it's the horse abuse that I crave. We need a new smiley on this board Steve, one that's laying on it's face.
