2005 GMC Yukon oil pressure extremely high.

You may have to pull the oil pressure regulator to clean out the relief valve / plunger. Some times it is accessible from the side of the block and with others the pan has to come off as it is a part of the oil pump.

1999 suburban gage oil pressure is 0 when it warms up. rpm drop to 3-4 rpm when oil pressure goes to 0. Sounds good, runs excellent -no noise. Actually it sound better then most new cars. It is so...

I looked at info for 1500--5.7L engine.
6 psi @ 1000 rpms
18 psi@2000 rpms
24 psi @ 4000 rpms

Sometimes, you can use analog gage in place of oil pressure sending unit and double check oil pressure that way. If oil pressure is actually low, if high mileage engine, I doubt replacing oil pump will help. I just wanted to add, check oil pressure engine warmed up.

My high milage 2000 GMC Sierra has an oil pressure problem when cold the pressure is good but as it gets hot it drops to the point the low oil pressure light comes on. I believe it is either the oil pump...

The oil pump is on the front of the engine. the pan and front of the engine has to come off. the crankshaft drives the pump. the cross member bolts in. you may check the oil pick up tube first. sometimes a mechanic has a bore scope and can go up in the oil pan drain hole and look at the screen. Its a lot of work/money to be guessing. good luck

I have a 1987 gmc suburban and the oil pressure gauge at start up reads about 35 to 40 but after driving a while will drop to 15 is oil pressure switch bad

It depends on your mileage. It's normal for the pressure to read high on start up and then drop some but your numbers are a little low on start up, usually on the high side of 40-45.You could check your pressure with another guage and see if it reads any different. If it does then you should change yours. But if your mileage is running on the high side of 200,000 then it's probably wear and tear. I would be inclined to try a heavier oil, 15-40 or 20-50. This should bring the pressure up and help with lubrication. You could also add something like Lucas to your oil to help with lubrication and pressure. It's also possible the oil pump is wearing out but unless the mileage is below 150,000 it likely won't do much good and a new pump won't like the heavier oil.
If you are unsure of the mileage you could do a compression check. If it's 100 or under the engine is worn.There is still life in it as long as the numbers are close together but it is time to start thinking about the next step.

High oil pressure 5.7L GM

Higher than normal oil pressure is usually caused by a stuck pressure relief valve in the oil pump assembly.

Low oil pressure on 2001 Suburban

your oil sensor comes on at less than ten psi, you may have internal engine damage how many miles on engine, any gum up inside engine, you can try to put on a high pressure high volume melling oil pump to try to help for the time being, but you may need to have it torn and repaired.

Oil pressure drops once it gets warm

Sorry to say it sounds like the motor is gone. Higher oil pressure when the oil is cold is normal. But, when the engine gets to operating temp and the pressure bottoms out and the engine knocks you have big problems. If the mileage is very high (150,000) or more your bearings are so worn that the oil can't fill the void between the surfaces and thus the low oil pressure.
