This afternoon, I started to put down the street @ ~ 18 mph top speed, noting as often that the old 727 was taking its time shifting up. I then started to hear a little lifter chatter at a stop sign. "Odd, I just topped up w about 2 oz of 20-50W synthetic. Hmmmm" I turn. The chatter worsens. I look, see 0 psi oil pressure! Full stop! Motor switched off before car ceases rolling.
I get out, tap the body of the oil pump lightly w peen hammer in hope of jarring loose any possible crud there. I add an extra pint of 20-50W, crank the motor, and make the 3 blocks home sans any worse noises. I cut the ignition as soon as parked and it will stay OFF until this issue is resolved. (I dare not leave Mathilda on these streets! There are plenty folk with towing ability and she turns many heads even as she is...)
Seeing the previous thread on sudden, mysterious loss of oil pressure, I read through it, checked the distributor shaft and noted there is NO oil in the filter. The distributor shaft is intact, and likely the original if appearance informs me correctly. It IS nicked, but the end appears to be at factory hexagonal shape. The utter lack of oil in the filter and sudden onset of this rude surprise incline me to suspect the pickup is clogged.
Shall I drop the pan NOW, or have a look at my pump first? I normally got around 15-50 psi out of this pump between 500~3000 rpm, very seldom taking it over the modest 3 grand except for short hops on the interstate. I suspect an aged pump has lost its prime, though WHILE RUNNING seems unlikely, so I may well have a load of crap clogging the pickup. I KNOW the transmission filter was horribly neglected, and only within the past 2 weeks has that been corrected. I just HATE having to drop the pan, unless there is NO other option.
Have I any other option, aside from letting the car rust?
