[TR] oil pressure

[Randall]

IMO 80-85 is OK.   But I wouldn't go any higher as it will be more apt to leak (plus the possibility of blowing the oil canister
off) and/or shear the drive to the oil pump.
 
That said, I had a freshly rebuilt TR3A motor that would hit the peg on cold starts even though the valve was set to 70 psi.
(Something about straight 40 weight racing oil in winter <g>)  And it didn't appear to suffer any ill effects before I changed the
oil to a grade more suitable for winter.
 
But before changing it, I'd double-check the pressure gauge.  They sometimes read high, even if they return to zero.

Is there any concern over high oil pressure?  On a newly rebuilt tr-3 motor I'm getting 80-85 lbs. of pressure at 60-65 miles per
hour.  I love the improvement in pressure but am wondering if it's too high.
