Just changed the oil because of low oil pressure and it was dirty, but it continues to have low oil pressure and has clicking and some squealing sounds -01 chevy camaro

Clogged oil pump screen. Do not run vehicle with low oil pressure. you will do more damage than good. needs checked out by a professional quickly.

Sounds electrical (bad earth, chaffed wire, dirty fuse) but get the garage to put a oil pressure gauge on the car to make sure the oil pressure isn't low.
ABS light will mean brakes still work but not as efficiently so drive with care particularly in the wet.

have the oil pressure checked with an independent gage as sometimes gages in the dash don`t show correct pressure. how long has it been since the oil was changed as oil when it gets dirty it thins out and can affect oil pressure. if you don`t hear any ticking with the motor running chances are the pressure is either good or just a little low. testing oil pressure with an independent gage will tell the tale.

It is coming on telling you you have low oil pressure and when you accelerate it builds enough pressure to go off.
1. Check the oil and make sure it isn't low
2. If that is OK, is it in need of an oil change as sometimes filters can become dirty causing lack of oil pressure.
3. It could also be a faulty oil sensor, but most likely it's 1 or 2

You have low oil pressure which names that you sustained a high pressure of oil and now it's really low

stop and check the oil level .if ok but very dirty drain it do an oil and filter change .does not cost a lot for that to be done in a garage .check online near you.

Low oil pressure will cause engine knocking at idle. Pressure climbs and properly lubes engine at higher RPM> Check your oil level.

Squealing may be caused by a loose/worn belt on the power steering system.

1. You are low on oil.
2. The engine/oil pump is worn and no longer provides sufficient oil pressure at low idle.
3. The oil is very dirty and needs to be changed.

Do not assume that the low oil pressure warning is a false one or that you only have a faulty oil pressure sensor. Your engine may in fact be running with low oil pressure once the oil heats up and thins out. 8-10 miles of running is enough to get the oil hot. It is significant that you only get the low oil pressure warning once the engine oil is warmed up.

If the oil pressure in the engine is low, engine lubrication will be impaired and the engine can be badly damaged so you need to run an engine oil pressure check.

1. How long has it been since you have changed the oil in the engine? If it has not been changed in the past 6 months then change it and change the oil filter at the same time. You must only use the oil specified by VW for that particular engine.

2. When new oil is heated it thins. If it is old and contaminated it will be even thinner when warm. You will get less oil pressure when the oil is thin and hot and more oil pressure when it is thick and cold. Fresh new oil is a little thicker as it has not been diluted with petrol and other contaminants.
Oil pressure also varies with engine speed (RPM). At idle or low engine RPM the oil pressure is lower.

3. OIL PRESSURE CHECK
After the oil is changed the car needs to be run to check if the oil pressure warning still appears. (I suspect that it probably will). If it does appear then an independent oil pressure gauge needs to be connected up to the lubrication system in the car to check the engine oil pressure. This is best done when the engine oil is hot because this is when you are getting the low pressure warning. Any competent mechanic will be able to do this. ( The useless ones will not). The oil pressure can then be properly checked on the gauge at various engine RPM. If there is a low oil pressure reading from the gauge then there could be a problem with the oil pump, the oil pick up or the oil pressure relief valve in the engine.

4. You mentioned that you see the oil pressure warning disappears once you accelerate. I suggest this is only occurring because with an increase in engine speed (higher RPM) the oil pump speed is increasing and the low oil pressure problem is being overcome temporarily. However as soon as the engine RPM drops the oil warning will appear again which means the engine is running with below minimum oil pressure at that RPM.

Even when you get no warning, the oil pressure in the engine could still be running significantly below the optimum level.


5. It is possible that the oil pressure is fine and that the problem is an electrical gremlin as these cars suffer from a variety of electrical faults. However from what you have described I think there is a problem with low oil pressure in the engine and until it is properly checked it is unwise to assume that you are just getting false oil pressure warnings.

I hope this helps.
