[TR] drop in oil pressure problem

[hdrider570 at att.net]

The first thing I would check is the oil pressure relief valve spring.  I have seen a number of them that have thinned sections from 
years of rubbing against the bore that they are situated in, not to mention detempered from heat, and softened by being compressed 
for 35 to 50 years..

New springs are cheap and easy to replace.  I never put an old one back.
