Many thanks to everyone that responded to my post about the aluminum plugs
in the TR6 block. These are located directly above the oil filter and at
the front of the oil gallery. What I have discovered is the following:
Plug above oil filter (TRF part PU1404) is a 3/4 by 16 thread (UNF), which
I am replacing with a hex-socket set screw (SPAE-NAUR part 478-007)
Plug at front end of oil gallery (TRF part 118632) is a 1/2 by 20 thread
(UNF), which I am replacing with a hex-socket set screw (SPAE-NAUR part
478-001 or 478-002)
I plan to seal the set screws using Teflon tape.
Anyone who hot tanks their block should take care to examine these two
plugs, which in my case were "eaten" when the block was hot tanked. Removal
from an old block was impossible without drilling and collapsing the plug
with a punch.
Hope this information is help to others who encounter this problem.
Cheers, Mike Graham
