[Fot] TR4 rear main cap "leaking" shellac

[J.C. Hassall]

When I assembled my engine I soaked the felt strips in a couple of 
gallons of Indian Head Shellac.  Some seeped to the outside of the 
cap, of course, as well as dripped down the inside of the 
block.  I've driven the car for maybe 30 minutes of spirited fun 
since the rebuild.  Tonight I noticed a streak of shellac down the 
front of the flywheel inspection plate.  Is this normal?  I sense 
not, but am at a loss to explain why it would liquify again.  The 
split seal is leaking, which would cause hot oil to contact the 
shellac.  Perhaps it has dissolved the shellac?  I'll run a test tomorrow.

What say the gurus?

tnx
