If this issue is not closed.......
Whilst I was looking through my garage for some information for Brad at the
weekend, I came across my TR2 engine.
This also has three bolts and a stud with the two washers. The two copper
washers had a different sized hole in them , so I looked in my (UK) Moss
catalog, and they specifically give instructions about these washers. The
one with the bigger hole goes on first, and the slack in the fit allows the
oil to go through to the banjo fitting and thus to the Oil pressure gauge.
The one with the smaller hole fits after the banjo fitting and effectively
seals everything off. So they agree that the oil pressure is detected
along the stud without holes in it !
If you TRers across the pond don't have the UK Moss catalog (it may be
different to the UK one) then it is definitely worth having, mainly due to
the tips about rebuilds etc. I always look in mine before I go to the
Workshop Manual - I get the feeling that this is not available to you
either- I have a reprint of the original Triumph workshop manuals for my 2
and 4 (inc 4A) that I bought from the TR Register, along with a parts
manual for my TR4 There is a lot more information in these than the
'other' manuals that I have, which includes a Haynes TR6 manual. (someone
donated it to me as I collect manuals !) and various other manuals that
seem to be out of print nowadays.

may be that special bolt is supposed to be a banjo bolt? Not that I know
anything about 4's...
