JB weld is strong stuff, I would say the key is to be sure it is as clean and free of oil as possible before installation. I have used JB to attach things to the engine and it has held for years and still going. That being said it is external and not subject to as much heat or bathed in oil. I have one too I have not gotten around to installing yet.

I learned all I need to know about life by killing smart people and eating their brains.
