Im going to see how much the tool cost. That way at least ill know if its the cylinders or just the rings. That and ill call Cummins and see how much rings,mains,and rod bearings cost.I priced out those parts from autozone,But after looking around on here,Just about everyone seems to say go with the cummins parts. Sounds good to me. You just never know with these aftermarket parts. Ill keep posting on the outcome of this issue.
