Mr.T
DPF's are gay
So my wife and I have decided its time for the LB7 to go to a new home, so we're looking to upgrade to an LLY, LBZ, or possibly an LMM. Not knowing a whole lot about those years, what should I look for as far as mechanical issues, common problems.....etc? I know about the pump rub issue in the transfer case, was that repaired on the new trucks? Are the LLY's having head gasket and injector issues like the LB7's do? And I hear about pistons cracking on the lbz's? What causes that and is there any telltale sign of having cracked a piston or two? Anything else I should he looking for?
