Sorry for the hijack, but what is the torque for a magnetic drain plug? I bought one off a member here a few years back.
And I would have a little bit of a concern if you had a shop change the oil and now you have a leak from the plug. This should have been checked before your car left the shop. If you take it back I'd be worried that they'll just torque it down hard and possible damage the plug or worse yet, strip the threads in your oil pan.
replaced the oil drain plug with a replacement from pelican parts. Also replaced the crusher ring. Once complete, it was determined that the ring was the culprit. Hanging on to my original drain plug to use next time.
