Hi Wayne
Yes this is an aluminum plug ... it is actually sold as a "bar" with
several pieces all linked together (like a Rollo chocolate bar). You screw
it in and break it off. No idea why this is aluminum in the first place. I
discovered the hole when I had my engine hot tanked ... the aluminum
dissolves. Here is what I found out and how I filled the hole:
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). (I
used Kleen-flow gasket maker ... a red goo to seal and it has worked just
fine for the last 18 months or so ... teflon tape did not seal it well
enough I found).
Hope this helps, Mike
