Wayne,

That plug is an oil galley plug and is lead.

I would order the TRF part and have your machine shop install it.

Must be the same as any other engine. Make sure you use assembly lube on the 
cam and lifters, bearings and I also put some on the front and rear seals on 
my 6 project.

I used Brad Penn 30w break in oil on my recent TR3 rebuild. Just took it easy 
for a few 100 miles (not over 3000).

The Lucas stuff cannot hurt!

I ran the 30w brad penn oil for about 750 miles. Now use 20/50 Brad Penn 
racing oil. Lots of that zinc stuff.

I plan to do the same with my 72 6 project as I did with the 3.

The 3 and my 4 (which uses the same oil) run just great with great oil 
pressure.
