Perhaps I should knock on wood...but at 170,000 miles (plus) no
problem with thrust washers on the TR-6 yet! Tolerance check still
reasonable.
I only became conscious of the need to stay off the clutch in the last
six years or so...had the car since '80...so for some of those miles I
spent more time on the clutch than I probably should have....so, what
is this design deficiency so often blamed on the guys from
Coventry?????

The latest thread on 6 cylinder crank thrust washers is very interesting and
sounds like something that should be done by anybody rebuilding a block.
However, since I just had my TVR's engine rebuilt and I don't want to pull it
apart just to do this fix, I think it might be a good idea to just consider
these
thrust washers a regular maintenance item.
I think these can be replaced in my car with the motor in since the pan comes
off
easily (I've done rod bearings like this), but I don't know if this is
possible with a
TR6. It's definitely not possible with my GT6.
What I wonder is how often to do this- 5K, 10K, 20K miles? Any ideas out
there?
