So I changed the oil for the first time on my '11 F250, and I was not enamored with the new drain plug. Is it easy to tell you have it secure? Yes. Does it make me feel secure? No. It's like a damned Dzus body fastener.
So I decided to employ some of my shade tree skills learned in the pits... and safety wired her up. Didn't know if anyone else has done this (couldn't find one) but it took me 10 minutes (yeah, ugly wire job) and I feel much better:
I drilled a small hole in the flange around the pan bolt hole, and used stainless steel wire (found in JC Whitney, at Harbor Freight, etc.) to wire it up. Wire passes through the flange on the plug and is then wired to the pan.
KEY: REMEMBER the wire has to be PULLING the plug tighter, not vice versa.
