So I posted earlier about blown hg on lb7. Well I pulled it today, what a beotch! Anyway 7 straight hours. Stupid core support in the way hung me up for another hour.. To you guys that have pulled your engines any tips will be good right now like things to possibly replace that will be hell in the truck. I'm about to pull everything off to replace head gaskets with new studs reseal all injector sleeves, new rebuilt or whatever factory flow injectors. I pulled motor because the rear main is dumping oil like crazy. Anything else I should do that a may regret not doing later?
