<VV> Low OIl Pressure (at idle) Not Cured by More Spring Pressure

[Mikeamauro at aol.com]

>From an Earlier Discussion: "...At start up I have 25 psi at idle, but it  
only gets to 30 even at 3500 rpm. When warm it's hovering around 8 - 10 at 
idle,  but bringing the engineup to 3500 I only get about 20 psi. I'm 
thinking the easy  thing to try first is just swap out the pressure relief 
spring...." 
 
As I recall, the purpose of the relief spring is to prevent too much oil  
pressure when the oil is cold and thick, and/or under higher RPMs.The  
spring, I believe, begins to bypass pressure around the 30 to 35-psi  range... so, 
with the pressure being low at idle 5 to10 psig, adding more spring  
pressure (stretching or washers) will not boost oil pressure at idle. This is  
nwhat "me thinks."
