Need help 427 low oil pressure ?

[priobe]

patrickt,

The builder did break the motor in on the dyno. As a matter of fact he told me that the pressure was at 60 psi not sure the RPM. I recall when the motor was done I specifically asked him this question because I new that the FE had an oiling characteristic to them. The motor was built in 2004 and I would turn the motor over by had as it sat for 1 yr. When I fired up the motor the motor has 60 psi. I then installed the body and continued the build process and notice that the pressure would only go up to 30 psi.

I spoke to the builder and he told me that clearances are not the problem which I have stated the number in this thread.

The builder did mention that the heads are not restricted. But we both agree if it had pressure before where did it go?

Also all the oil plugs have been installed with epoxy so they will not blow out. I witness this myself.

The only plug which I still can not see is the one inside the distributor. I dont see how you will see it with a mirror. I tried using a coat hanger and bend a 90 degree end approximately 3 inch long to see if I could feel something or in this case feel nothing and I believe the plug is there. Also, with the drill in a reverse rotation I do not see oil spilling out from the front hole which is a good indication that it is installed.

Update: inspected the oil pump gears
1. height 1.09 inch - which is a HV pump
2. plunger inside pump moves in and out with some tension
3. gears look good with no scaring or pits
4. I was not able to remove the spring but I dont if this is the problem
5 I will problably replave the pump with a Precision Oil pump unit w/ spring kit just to be on the safe side

Any thoughts?
