When changing the oil on my 86 Westy, I thought the drain plug seemed odd. It turns out that one of the PO's has broken off the ceramic and ground the electrodes off a bosch spark plug and used it as a drain plug. This is a new one to me. It has been serving its purpose but I decided to replace it with a regular drain plug, 14MM x 1.25 threads. Turns out the first 3/8 of the threads are stripped and the shorter threaded plug will not bite. Do I leave the 'bonus' plug in? DO those rubber drain plugs meant for stripped threads really hold? I don't want to drain the oil all over I-81 on my fall trip to the finger lakes. Any advise would be appreciated, ChrisChris, get it fixed right!!! Have a shop install a helicoil insert for the proper plug. Then always put on a new gasket on the plug every time you have that plug out. That way you will avoid the problems.
