The screw that is used to fill the void where there would be an exhaust nipple on my Hatori pipe is loose again. I originally had it red loctited but as expected the loctite got hot and the screw loosened up. Is there any such heat resistant epoxy that will work to hold the screw in place? Maybe something I could pick up at home depot? I have a feeling that if I tighten down too much on this screw that the threads are definitely going to strip.

Heli 770, is that the same stuff people use as a gasket between the pipe and motor?

You might be suprised how well a normal split lock washer works. I also used a touch of teflon tape for a proper seal.

another option, if all else fails, like lock tite, i would use JB weld. use brake cleaner or electrical contact cleaner (they are both the same thing) to flush out the threads, this will make sure any lock tite or JB Weld will stick properly.

if that fails, re-tap it for a larger screw, flush it out, smear some gasket maker silicone (high temp silicone) over the new clean bolt, thread it in, and away ya go.
