Hello wonderful people of bitog 1999 Sierra 1500 Went to a fast food restaurant and embarrassingly got into my first little accident. The fast food joint is in a very weird property where looks like it was a shared lot but what was next door got torn down. The drive thru wraps around the place...

1999 gmc Sierra 1500 with a 2003 4.3 engine. Absolutely no leaks from anywhere. Zero smoke out of exhaust. And okayish compression on each cylinder being 155 across the board does that mean the piston rings are probably not wrecked? Motor oil keeps going low after about a week. Would bad pcv...
