[Fot] Rear main rope seal alternatives?

I recently disassembled the engine from my TR3 and the rear main area was dry.  This was my first TR engine build.  I used the orange RTV and carefully watched it just squeeze through gaps and cracks around the bearing cap as I installed the rope covered in RTV.  That is the only place I used the orange RTV on the engine or anywhere else.  I made a rope install tool just like Kas suggests in his book.  What I did find was that the front engine plate was leaking between the plate and engine at the bottom.  Oil from this leak makes it's way all over the oil pan and drips off the bolts and back from there.  Also, my trans front seal was leaking and that slings fluid around inside the bell housing then drips out the hole at the bottom.  The slinging oil also finds it's way out around the clutch fork shaft exiting the bell housing.  These two leaks made it difficult to tell if the rear main was leaking or not.  I also found trans fluid coming from one of the bolts holding the tail housing on.  These obviously need to be sealed up better than they were.  At least the rear main wasn't leaking.  I'll be more confident installing the rope seal this time around.
