Have 6.2 diesel, tci 700 tranny( engine's other wise stock). Heard a loud bang one day. Pulled over and saw a crap load of oil oozing outta the rear main seal. Looked like molases. Tore it apart and saw a huge hole in the #5 cylinder wall. Head gasket took a sh!!t and all the anti freeze mixed with the oil. Bought a whole new bottom end. Just wanted 2 post and see if anyone had any 2 cents they wanted 2 throw in. Diesel shop I spoke with said that it (fuel) leaned out and caused the explosion. Having injectors/and pump tested asap. Just wanted 2 hear from some oil burners on this issue is all.
