Bill,

As part of my engine rebuild last year I had Triumph Rescue install the new 
and improved rear main seal.

After installing the engine, I noticed a very large oil leak at the rear.

I called Matt and he said he would need to inspect the engine while in the car 
so he trailered the car from central NY to his shop.

After some test driving and test runs he decided to pull the engine and 
inspect the seal because he said the oil leak was much more than expected.

What he found was a seal that was "too" tight. The seal was actually twisted.

This was the Moss seal so he called TRF and installed their seal which is in 
the car now. I only get a drop no and again which is less than with the old 
mechanical seal.

I would call Matt at Triumph Rescue to see if he has any suggestions. He came 
through for me and he has a lot of experience with that type of seal.
