Lovehamr,
I have tried 3 gauges:
Stewart Warner -Electrical - does not move cold or hot (gauge does not rest at zero. Sits between 0 and 25)
Moves pass 25 when you hit the gas.
Cheap Advanced auto gauge - Mechanical - 15 psi at idle cold & hot - 2000 RPM 30 psi
Snap on mechanical gauge- with drill spinning counter clockwise 28 psi cold did not try hot or with motor running
Vettestr,
I dont understand how I would bypass the external relief valve ? This relief valve is in the back of the block.
Cold startup is around 15 PSI and I am measuring the pressure before it enters back into the motor like most of the people on here. I have not yet connected my
oil cooler because of this problem nor do I have thermosat to control the
oil flow. It is basiclly 2 lines from the adaptor plate to the dual remote
oil filters and back into the motor. I am using 20/50 Valvaline
synthetic oil.
Update:
I spoke to Doug at Precision Oil Pump to purchase a pump even though I dont need one. Doug stated that
synthetic oil's will cause you to lose pressure compared to Dino oil as long as all else remains the same. He also stated that idle oil pressure should be 15-20 PSi warm @ idle and should climb to 45-60 depending on clearances.
I have read many articles /threads with people having very simular problems and never posting what the problem was. Also, I have read people mentioning that they get 30 + psi @ idle (assuming idle = 650 - 900 RPM) and Doung mentioned that the spring in the pump does not control pressure at idle.
The pan that I am using is a Armondo Pan with a total of 11 QTS of oil.
I dont know what else to include. I am waiting for a response from my engine builder to find out what restrictors were placed in the head. (would this make a difference.
P.S. I have also check the plug inside the distributor and can not find it. But before disassemble of pan and pump with a drill I did not see oil gushing in that area. I am assuming the plug was installed : I also verified with the builder and he recalls the plug being installed.
Note:
Boy those pistons sure look nice when looking underneath and the pan off.
If I continue to disassemble more things I might as well rebuild the motor
