The worst has happened - no oil pressure

[Eliems]

I restarted this thread because I need your help. They are telling me I need a complete rebuild! The pressure releif valve was the culprit but the bearings are now toast! 450 miles on this car!

They are claiming low oil pressure before the oil change as I told them the guage read quite low at idle ( below 20 lbs ) but rises with RPM.

QUESTION: what should the oil pressure be for a 429 Cobrajet, 10 1/2 to 1 comp. mild cam, at idle and at 2000 RPM ... 3000RPM ?

Thanks Guys!

Hello folks, great forum! I am two weeks into owning a beautiful Custom Cobra and loving it! Tight car and power unlike anything I have ever encountered.

Took her in for an oil change as only 350 miles on the rebuild but the car has sat for five years with only occasional sart-ups and the oil was 2 years old.

The mechanic took her for a test drive after the oil and brake-fluid and coolant was changed and noticed no oil pressure on the guage! Had it towed back to the shop!

Changed the filtre in case it had been faulty ... still no pressure! Tried their own guage and no pressure. Oil filtre remained cold and the transparant oil tube to the guage showed no flow.

Tommorow they try to operate the oil pump through the distributer, maybe the drive shaft has broken from the distributer to the pump. maybe the pick-up tube from the oil pan has fallen off, maybe the oil pump quit for some reason??????

Have any of you had this happen?

Thanks!
