Low oil pressure in 1998 camaro ls1

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.

the clicking sounds could be weak lifters or your oil may not be heavy enough depending on the mileage

When the engine and oil are cold it will show a high pressure because of the viscosity of the oil. When it warms up the oil is thinner. If it doesn't drop below 20-25 psi at warm idle I wouldn't worry about it as that is normal.

Good gas mileage on this car should be 19City 27Hwy. Gas mileage can be affected by many things. Assuming that the car has been recently tuned as you have indicated, I would: Check tire pressure first<-you'd be surprised what low tire pressure can do. Check for low oil level <-engine friction Cheap spark plugs. Let me know.

Oil light on is BAD. the engine may be toasted. Have a Shop check OIL PRESSURE.

At some point, your engine is registering low oil pressure and warning you the oil pressure is insufficient to lubricate the engine properly.

How does the engine know this? What causes it? Excellent questions. The engine 'knows' this because there is one or more sensors that read the oil pressure all the time. The sensors report to the computer which reports to you. They could be faulty. On the other hand, there could be times when oil pressure IS low. Your oil pump may be mal-functioning. Normally, I would expect the oil pump to either do its job properly or NOT do it properly but not act intermittently. It may warrant being checked by a professional. Another reason for this condition could be the oil itself, though you report you just had it changed. Presumably, whom ever did the change put in the proper oil grade, service and weight, recommended by GM.

Another thought, is this warning seen by you immediately after you start the car? If yes, it is normal for oil to take a second or two to build the proper pressure, particularly in cold weather. Where I am at, it is cold. Oil doesn't like to move when it is cold (like me) so it takes a bit of time to get up pressure (like me).

If this continues, you may want to have this problem looked at by a professional, as I said.

Until u have a mechanical test gauge hooked up to verify the oil pressure is ok assume it is not a good idea to drive, low oil press will destroy a $4000.00 engine very quickly.

Are you sure it's your oil pump and not just a faulty oil sensor. Don't know if you have a V6 or a V8 so can't really help you more on where the sensor's are.
note: you get your oil pressure from the crankshaft and the oil pump really brings the oil to the top of the engine to keep it simple. 
Good luck and hope this keeps it really simple and save's you money.

they are full of it, u should show oil pressure as soon as the engine starts, this may be a sticky guage or a sender but that advice they gave u is bull, that is for sure, I am a GM technician.

no oil on ground oil still full but after it runs for a few minutes oil pressure drops
