[TR] TR4 Oil Pump Priming

I takes a while for the system to "prime" and fill with oil upon 
first startup.  That's the purpose of running the oil pump with the 
dist shaft or turning it over without plugs until you see oil 
pressure before first startup.  The lube you put on those parts 
during assembly is the only lube until oil runs through the 
system.  A certain amount of oil stays in there afterward.

The assembly lube doesn't last long when no oil is running through the system.

Doesn't hurt to do that on an oil / filter change too - spin without 
plugs until the filter is full and you see oil pressure. Then start it up.
