Thanks for reply RJ,
With a little more research I see quite a few early British cars used simil=
ar rope seals for crankshafts .. but now, most, if not all marques have mod=
ernized replacements available - as you have fitted.Seems best way to go!

Carl,
I was not aware of the ropes used on other British cars, other than my Aust=
in-Healey, which still originally leaked oil at the rear crank area.
For both my TR3a and Healey, I installed the after-marked rear seal kits, w=
hich eliminated all oil leaks from the rear crankshaft area.

Subject: [TR] TR Rear Crank Seal Rope?
Hi Listers,
This has been on my mind for quite some time;
=C2=A0Why do TR2 through TR4A rear crank seals NOT USE a graphited rope in =
the 'purpose-made' groove in the scrolled aluminum holder, when Jaguars wit=
h the same type of 'scrolled' crankshaft/seal groove do, as well as some ea=
rly Ford, Jeep and other brands of motors?
Did the Triumph engineers decide against it even though the rear aluminum c=
rank seal parts were already cast?
The special graphited seal rope is still available at Moss (for early Jags)=
and other makes of that period..
And I recently read that someone found a rope seal in their TR4 crank seal =
upon tear down!.. and he mentions that prior to tear down the rear crank se=
al leaked very little.
To me, it looks like the TR motor rear seal was designed to use a rope just=
like early Jaguars yet no mention in TR factory manuals.
Been tempted to add the graphited rope.. why not?Regards,
Carl
