I'd put my hand up if I thought I'd been the cause, but like I said, I was suspicious of this plug from the outset. First time I changed the oil I noticed it was strangely tight to UNscrew, and hard to get it to bite to screw back on. Whether it came from the factory like it or whether it was done at the first service, I don't know. I know I made a mental note last oil change to leave it alone and drain only from the gauze plate, but I forgot!
Not guilty. I know about torque. Honest guv.....
