[Fot] Type A OD leaks

Very good idea not to use gaskets that can compress! (like "gasket makers").

I don't use the gasket because it can compress slightly when things get loaded in use. 
I go metal on metal, chamfer/deburr/dress the mating faces, clean, Permatex "right stuff", good grade 8 bolts & red loctite. 
Done deal...

I removed my TR6 type A OD box out of the TR3 race car today. It was removed because the last time on track, it was leaking badly. 

To my surprise, I found that the OD adapter plate was very loosely attached to the rear of the transmission, in fact two bolts had completed backed out and I found them when I removed the accumulator piston cover. Upon further disassembly I found that all of the adapter bolts were loose. 

When I built this transmission 2 years ago, I used red locktite on all of these bolts. I also had use the thin gasket with hylomar. Has anyone every seen these bolts back out like this before? Any suggestions on repair work to make sure this doesn’t happen again? 

I’m thinking of drilling all bolt heads and safety wiring all of the. Have also thought of using helicoil on all of these since they are threaded into aluminum. 

Appreciate all thoughts on the mater.
