2000 gmc yukon 5.3L 4x4 Is the rear main engine blockseal hard to replace. I changed oil to heavier weight due to lifters noisy on startup and 300 miles later rear main leaking out of bell housing (6"X1' PUDDLE OVERNIGHT). Should I just rebuild engine or swap out and what is the best place to find one. Could I just replace seal?
have the same problem?
