Dang Dave, sucky. I think I'd still give up my left leg to get your pickup, even with the hurt engine, lol. Just had another thought after reading which cylinder it was on PSN. Maybe between the partially filled block, long towing trip, no.7 cylinder(possibly hotter at the back) the engine just got to hot? Is the scuffing up the entire piston or just the lower part of it?
I also read you thought the cooling jet was restricted, anymore checking into that jet or the jet(s) on the other cylinder(s) with bad leakdown?
