Last night running at about 3200 rpm the oil pressure dropped to 0 suddenly. I threw it int neutral and pressure came up to 40 psi let engine come to idle and shut her down. Checked bulge for signs of oil spray bilge was clean. Sat for ten minutes and fired her up kept the engine just above idle while monitoring oil pressure. It stayed between 40-60 for several minutes then dropped rob 0 again. An hour and a half later we loaded it on the trailer after getting a tow from the park rangers.
What would cause the pressure to drop like* this and not be leaking externally?
I rebuilt this engine beginning of the summer (see thread on Siezed 5.7 teardown).
Can I scream yet?

... i'd have to chase the easy first.... maybe bum/ borrow oil gauge and sending unit... make dern sure that the info your getting a your gauge is correct, seems like the minute a engine went to 0 oil pressure, that it would get noisy quick, when you look in your valve covers, are the rockers wet? hope this ends up easy fix, and you can scream whenever you choose, but it scares the dog....and then ya still gotta break out he tools.....have a good day.........Mark
