So for the second time, my LN plug has failed, the shoulder has sheared off again from the threaded section. The first time it failed made sense. I had overtorqued it since Pelican said the torque value was the same as the OEm plug, 37 ft-lbs. They have since changed to the correct spec of19 ft-lbs. The new plug I have has been removed maybe 3 times and always torqued to 19.

I had noticed some oil on the garage, so a couple of nights ago I put down a piece of cardboard and had a good amount of oil on it in the morning. I thought, great, its the RMS or IMSB that failed. I looked under the car and the mating area between the motor and tranny were perfectly dry, whew!

Then I note a drip from the plug. when I put the torque wrench on it, the shoulder came completely off. I was very close to losing all the oil in my car.

I just don't have any confidence in the LN plug any more. Is there an alternative mag plug?
