On 2003 Cadillac Escalade The Oil pressure gauge is below the 0 area but moves farther down and movesup and down below 0

you can not have less than zero oil pressure so the indications are that there is a fault with the oil pressure sender or oil pressure sensor
you should take the car to an accredited service center and have the oil pressure tested using a mechanical gauge to prove what oil pressure you have
from there you have the faulty item replaced

I would say that you are definitely low on oil pressure. The oil pump is usually located inside of the oil pan. Depending on what vehicle you have you might have to have the engine removed to access the oil pan to get to the oil pump. I know on a Cadillac Northstar engine you get 43 hours to do an oil pump.

Blue smoke out of exhaust

#1 suspect is the oil seals in the turbo, especially if you use a gause/oil air filter instead of the factory one (known as a "dusted" turbo).

Your oil pressure gauge works with the oil pressure sensor, which is screwed into the block, to transmit a reading. A faulty oil pressure sensor can cause the reading on the gauge to be erratic. You may have a bad oil pressure sensor. You should also inspect the wires going to the sender to make sure they are not loose, corroded, or shorted. If a new sending unit doesn't work, you can check the oil pressure with a manual pressure gauge. Testing for oil pressure involves fitting the oil pressure gauge with an adapter. Then you will need to determine if you have a gauge problem or an actual oil pressure problem.

Oil pressure high, oil level low

Oil pressure and oil level are two different creatures.

your oil gauge determines oil pressure while the oil can (red light on dash) indicates oil levels.

There are usually two different sensors but can gauge the same types of things. E.G. - If your oil is so low that your pressure gauge is affected this can cause engine failure. Thus--a good rule of thumb is to check your oil once a week as the oil pressure gauge and red oil can may not always work as intended.

I hope this helps!

Low oil pressure is a serious problem and should be checked right away. Either the oil pressure sending unit is sending the wrong pressure, or the oil pressure is too low due to an engine problem. A shop will be able to verify the actual oil pressure with a mechanical gauge. If the pressure is really okay, they can then change the sender or look for a faulty oil pressure gauge. If the pressure is really low, meaning that the sender was correct, the cause for the low pressure must be dealt with before expensive engine damage occurs.

Possible causes for low oil pressure include: wrong grade or weight of oil used, clogged oil filter, clogged oil pick-up strainer, engine running too hot, oil pump worn or damaged, idle speed too low, and oil pressure gauge working improperly.

It is doubtful that the oil pressure and the speaker problems are related. Engine controls and indicators and body accessories are generally on completely separate electrical circuits.

Sounds like they failed to remove the old oil seal on the filter shaft check to see if you suddenly have 2 seals this could gause the problem.
