List:  what is the general consensus about replacing rear oil seal conversions?
 
I have a smallmouth TR3 which is pulling well way past the 5500 rpm mark, so rather than risk a failure of a 60 year-old cast iron connecting rod, I think I will pull the engine and install steel rods.  I had thought about a steel crank, but the 4-cylinder engines have a remarkably robust crank (and money does become an option).  The car has many upgrades, and I really should have gone with steel rods originally.
 
Anyway, the engine has the Moss rear oil seal conversion (with the machined crank).  Should the seal be replaced as a matter of routine?  The engine only has about 2000 miles on it.
