This is in a TR6 and I chose the latter style cover with the idea that =
it had more surface area. If you are familiar, the later TR6 aluminum =
cover has a recess that wraps around the ring gear.=20
=20
The car ran all day Saturday, almost eight hours straight without =
overheating, with synthetic gear oil. It overheated Sunday at 5.5 hours =
and I think it was a pinion gear failure that heated up the oil =
excessively. Still, the finned cover is a good idea and I just ordered =
one. 285 LB=E2=80=99s or about $375.00. They had the lower steering =
knuckles too so I=E2=80=99ll be replacing the rubber upper joint.
=20
Thanks FOT for the parts knowledge and lookup. It is much appreciated.

Those bosses could also be used for a watts link setup. Like Bill, I =
would have to remove my pan hard rod to fit this cover (which I am not =

diff oil cooling as a problem. I would also look into modifying a TR5/6 =
rear cover which looks like it has more capacity than the stock steel =
one.=20

Just a quick update. We were beaten by equipment at approximately 1:30 =
yesterday afternoon. Although certainly disappointed not to take the =

We were racing cars from the past two decades with a few exceptions. Out =
of 100+ cars, there was a pair of 60s mustangs, an Opel with a LS motor =
and us. Friday we finished 47th with 114 laps and yesterday 73 with 81 =
laps. We were averaging 3:10s around the full F1 course. As a point of =
reference, the leaders were running consistent 2:50s. A certain pair of =
drivers on our team were clipping close to 2 minute laps and both swore =
they weren't pushing too hard, maybe.
We were running with 18 month old 200 tried wear tires that had been =
flat spotted at the last race. This became very noticeable at 100+ down =
the straights. We again limited RPMs to save the motor. With a 3.7 rear =
end and no OD we were full speed about 1/2 into the straights. This is =
where the leaders would pass us.
Some of you recall last summer we raced this car with WRL in the June =
Texas heat and had some issues with lower than desirable oil pressures =
and a diff that boiling its juice.=20
For the engine side of things: This time around we installed an oil =
cooler and used VR1 full synthetic. Oil pressure at full tilt was 90+ =
all weekend and 40-50 at idle at pit stops. Problem solved. I am very =
impressed with synthetic motor oil. The oil still looks brand new after =
13+ hours of racing. I know from past endurance races with Dino oil, it =
would be pitch black and stinky at this point.=20
On the diff side (not so good): after boiling the Dino based lubricant =
last summer, we opted to simply switch to synthetic. This seemed to be =
working on Friday as our diff catch can stayed dry. We had some terrible =
noises coming from the rear end on Friday that we thought were hub =
bearings going out. The hub bearings are still suspect and will require =
attention. But our more serious problem was heat in the diff. The diff =
puked at about 1:30 and our day was done.=20
Last summer Keith mention his solution was a diff cooler and I think we =

we may end up with a triumph that can go the distance, eventually.=20
We were so close this time.
