Had that very problem with my 64C coupe many years ago. The flywheel face had been machined to too great a depth. Would have taken a stack of shims to get decent endplay.

The engine now has about 1000 miles on it and is running very strong. Any ideas?
I suppose the same could happen on the flywheel face too.

And when (like any service activities) did it start leaking?Vic Skirmants wrote:Where EXACTLY is the leak occurring?

It could be from the dowel pins. Put a bit of green Locktite on each before final torque of flywheel nut.
