Oil Pump Failing?

Well here's a secret. That and the temp gauge are idiot gauges. They always stop at midway, but they don't give out any information after that unless the engine is seconds from committing seppuku, at which point, shut it off.

Went to the local Jaguar Dealer this morning after calling yesterday and explaining the problem. They said "sign here" and pay us $125 to diagnose the problem, and if it's the sender switch, we don't have that in stock, but if we did it wouldl cost $136 plus labor to install." I walked out. The way these guys operate to find out what's wrong is wrong. There should be no diagnostic charge. And they wonder why their shops are a bit empty. Sure, there is a step by step logical approach but skip a step every once in while, or lose business.

Could it be the bearings?
or could it be debris?
Next step? They changed the oil to 15/40 per my request. Slightly less likely to show low oil pressure. Should I go to a higher viscosity and or Lucas Oil Stabilizer?
This car is basically running perfect other than the low oil pressure warnings.

Until you are sure exactly what is going on pressure wise it's guesswork. Back in the day we had a Smiths Industries mechanical gauge test kit with a selection of adapters to check oil pressure at the sender outlet. If you can get hold of a known good gauge and connect at the sender point you will know exactly what the pressure is and that would help. Low oil pressure at idle speeds is a classic symptom of worn bearings but could also be debris( from tensioners???) blocking the oil pump pick up screen. I think I also remember a post on here sometime ago where the oil pump pick up pipe had worked loose. If it was my car and I couldn't get hold of a test gauge I would drop the sump and have a looksee.
