[TR] tr-3 rear motor bearing

[Rye Livingston]

When I rebuild my engine last year I bought the Viton seal, I used Permatex Ultimate red I think. I cut the felt into about 1+ inch pieces, and then kneaded the Permatex into the felt, major mess on my fingers. Dave Hogye loaned me a screwdriver he'd ground to fit the channel, and I tapped each strip down in place, to the point I had Permatex oozing out in places. It worked great, and there are no oil drips.

Doing it after the fact from below, that's gonna be interesting.

Both resulted in a reduction of the leaks at the rear main but still plenty of mess on the mat that I keep under the cars to try an protect the floor.  Current TR3 has a TR4 motor with no leaks at all, wish I knew what was in there, don’t know the PO.

> I'm pretty sure that I didn't pound enough soaked felt around the bearing when installing and my question is for those more experienced than I am:  Is it possible to pound more felt in from the bottom up rather than pull the engine?  I'm sure it would be a heck of a sloppy job if possible but I dread pulling an engine on a newly restored car.  Probably would simply deal with the leak and enjoy the car!
