I would find a mechanical guage that will screw directly into the block to make
sure my sensor hasn't gone bad.

-1600 DP Stock Engine ...16,000 miles on building it.
-VDO Oil Pressure gauge and sensor.....
When I start the engine , oil pressure is fine but after running for
15 or so
minutes when oil temps get up to 200-205 ( oil pressure ok at 40-45
psi )
but when I come up to a light or stop sign the oil pressure drops to
0. Oil
light comes on and stays on until the rpm's raise above idle (900
rpm) when I
drive off. ????
Then I go on my way and everything seems fine until I stop and the
oil lights
comes on again.
When I first get in the bus the engine is warming up (120 to 180
degess) the
first 15 minutes or so when I come to a stop sign at idle the oil
pressure is
10-20 psi.... seems fine. Frustrating,,,,,,
I replaced the oil pressure relieve and pressure springs and the
plugs which
increased my oil pressure but after 15 minutes (Oil temps 200-210) the
pressure drops to 0.
Any ideas?
Running Castrol HD 40 wt. It's hot here in Houston but never had the oil
pressure ever drop to 0 before like this. Engine was built 2 years
ago. No
visible oil leaks anywhere.
Help....
