I get Intermittent dash chime and oil pressure guage loss/bounce when its really cold out. I have replaced the sensor itself and problem still happens on occassion so I beleive its maybe the wiring from the sensor into the harness is just old and perhaps corroded and I have yet to follow up and do a 100% inspection. Your troubles could be the same coincidental bad guage connection and perhaps you actually still have good pressure but can see the concern if you truly beleive no oil is being pumped up.
Is there a way to test?? other than running the truck with a valve cover removed (AKA like a Chevy valve adjust 1970's era) or can you screw like a compression tester into the sensor mount to verify (asking cause I do not know).
The Timing chain tensioner on these Motors only last IMO approx 100K miles after which their reliability is hit and miss. The Crower Chain might be the next one I buy too but the Magnum has a real 6.1 with the white sliders and 4 bands (so I was Told by the Builder whom I trust). Danny
Danny,
I actually removed the sensor and held my finger over the hole and had the wife start the engine. Nothing, I removed my finger and still nothing. This wasn't a prolong test but with the engine running I would think pressure would be instantaneous. Crower is a OEM set with a hole drilled in it for the offset plugs used to advance or retard the cam. 6.1 timing set would probably be the upgrade. This lost of oil prime, which is what it looks like to me has me baffled. Maybe cut the filter open to see if that could have caused a problem. IDK what's going on...
