Hey, New Member here... Have an 01' Dmax 6.6-LB7, 3500HD ext cab dually 4x4.. I got the truck dirt cheap cuz PO said needed head gaskets, as I got further n further into the tear down I realized the PO neglected the truck... Upon pullin the heads there was standing WATER on top of pistons, rust in every possible place ya could imagine, water/coolant in oil... Removed the block n oil pan cuz motor was locked up plus wanted to inspect everything before throwin it back together n hopin for the best... Well turns out couple pistons were rusted to cylinder walls, after removing a few found deep scoring on pistons n walls, some rust on bearings, n the heads were shot as well.. So now I'm starting just gonna start with a fresh block n rebuild it myself instead of worryin if the used Dmax motor I buy is gonna last a week or few yrs... I will continue to post my progress as time goes...
