Did you remove the pressure valve / spring and not install anything in the hole ?
Also,
Where could I get the plug for where the oil pressure spring goes in the oil pump?
Thanks

I eliminated both the spring and plunger and inserted an aluminum dowel in its place.
I shimmed the the relief valve in the oil pump.
With these changes I have an OP at idle of apprx. 70 psi.
At higher rpms the OP will climb to anywhere from 90 to 100 psi depending on oil heat and weight.
What I won't do is rev it up while its still cold. I wait until I see the temp gauge move before giving it any rpm's.
You should be able to find the plug at Melling or DSC. |
