i have changed the oil 35 times and always torque the plug to 30 ft. lbs. today after i torqued it i noticed a leak . first i thought it was the gasket . so i got a clean container and drained the oil. when i removed the plug it broke where the flange with the 3/8 drive attaches to the threaded part. fortunately i had a new one. if this happened and one was far from cummins or they didnt have one, could be a big problem . have a good look at the plug next time you change oil . hope it helps someone.
