[TR] Best Rear Oil Gallery Plug Sealing...

[Joel Justin]

I've always had a small oil leak (haven't we all!) from the back of my TR4 block. I always assumed it was the rear main seal. But after removing my gearbox  to address an issue with it, I discovered the rear main seal area was bone dry, but instead the lead was coming from the rear oil gallery plug. It's a threaded aluminum plug that I've always sealed with Permatex Aviation Form-A-Gasket. Apparently that's not an adequate sealer doe this application. What have people found that works? I don't want a thread locker seal solution as I do want the ability to remove this seal later if needed.

Thanks, Joel...
