<VV> [SPAM?] Oil Pressure

[Duane, Jim E.]

Hi Don.

If the engine is tight and 20psi at idle is as low as you go (assuming 10W-30 weight), then you are good!  More pressure or heavy oil = wasted energy IMHO.  The only caution is in the lifter and rocker arm department.  Small block V8 lifters and/or rockers may starve the heads of oil, but the solution there would be rockers and lifters designed for 'vairs.    

Best Regards!

Subject: [SPAM?] <VV> Oil Pressure
Importance: Low

I run a VDO electric oil pressure gauge on my '67 110 HP, as well as an 
oil temp gauge. Oil pressure registers a constant 30 PSI at road speed, 
regardless of the oil temperature, which usually runs 200 plus degrees. 
(It is sensitive to outside air temps.) .At idle, it will drop to 20 
PSI.  I have thought about adding the higher oil pressure relief spring 
 from Clarks, but have been wary about oil leaks, especially around the 
oil filter casting...the width of the gaskets are pretty narrow in 
places.  But the apparent lower than spec pressure hasn't seemed to 
harm the engine (drove 1700 miles to & from the Iowa convention) and 
have put about 15,000 on the car since I purchased it 7 years ago. Any 
thoughts on the increased pressure, good or bad?
Thanks, Don Rossbach
