Anybody got any ideas what this is. I've had the problem for a while, but it's intermittent and I forget to ask.
Yesterday I went down to Salford in the Sprint to use it as a tank transporter - fish tank that is. Motorway nearly all the way, and no gear changes at all for about 60 miles of reasonably fast driving. Anyway, when I got to the south end of the M61, where everything stops, it had developed this terrible judder setting off from stopped. After a couple of dozen of those - lots of revs and let the clutch out very, very gently -, it passed, and the clutch went back to be really nice and easy to use.
Comming home, same length of drive on the motoway with no gear changes, but no problems with the clutch at the west end of the M55. Obviously, there wasn't the same stop go work at the Blackpool end - not this time of year -, but there's a couple of roundabouts and traffic lights to get through. So I would have noticed, and it's clearly not happening the same every time.
As it's an intermittent, it's hard to be precise about when it happens, but I think yesterday's example is classic - it's definitiely mostly after a long run with no gear changes, and it goes away with use, not after letting the car cool down or anything. I used to have this problem with a TR7 Sprint a while back, and never did find out what it was then.
I'm wondering if its oil contamination from a leak from the rear crank seal that builds up with sustained running and cleans itself with some use.
