I had a low oil oressure problem with my 09 silverado 5.3, hovered around 18-20 lbs, even on a cold morning start, twenty degrees,kinda erratic at times (a little higher)and I had read on a forum that some people have had oil filter change fix the problem,being the cheapest and easiest fix I decided to try that first,truck was not due an oil change so I changed the filter only, I was running a fram filter,replaced it with a wix and the oil pressure came back up to 40 lbs.
Stumbled onto this video while researching low oil pressure. I have a 2000 Silverado 2500 4x4 6.0 with 288K on it. Just got my new sending unit in the mail, but didn't know about the screen, so thanks for the tip. I'm just gonna put new everything: pump, pickup tube seal, sending unit, timing chain kit, etc., because I only want to do this once. Engine runs great, and I hope I can squeeze a lot more miles out of it. Great job on the vid.
A huge item everyone misses. Check the Volm manifold bolts. Guaranteed you'll find them lose. Easy test, check the front two just under the air intake. if they are lose so are many others. You will have to remove the intake manifold to get to the rest. If you sender screen is dirty/plugged, your not changing the oil often enough. That should never be an issue if your changing your oil. If your concerned with you oil pressure, just behind the alternator is a gallery plug direct from the oil pump. Plumb into that spot and you'll have 10-20 psi over shown on scan tool or gauge.
My 2011 camaro L99 6.2 now has the (floating) 14-16 psi idle on hot engine 250F and 26 psi when temp is around 225F. Cold idle is 50 Psi. Oil pump and pickup tube are new. No metal signs in the oil filter. I can hear very light crank bearing sound that could be hear Only under the car. Ticking lifters sound (as usual) presents. Could you please advise is it normal ? 115K Mileage 5W30 outside temp 105F
Hey bud I'm having very low pressure on my 07 tahoe 5.3 I replaced oil pump and pressure switch and screen and oil and oil filter. Pressure gradually goes down after the engine is very warm and it has been driven for about a hour. It goes to about 10 psi and if I turn off and back on it goes back to normal and then eventually it'll drop down again after a while
I have an 07 LY5 5.3 LS. At 15 years and 75k miles the oil pressure was very low at idle. I replace the little screen under the oil pressure sender. Didn’t help. So I dropped the pan and took off the pickup tube. The o ring was hard and the outer edge was flat. It did not have any elasticity. New o ring installed. Oil came right up. That is the fix in my case.
Strange mine has new oil pump and new o ring fresh oil change kick myself for the fram filter definitely plan on changing that but it was fix now or replace engine type situation but i now have 40 psi driving cruising around 60 stays directly at 38 to 39psi soon as i come to a stop she drops to about 10 to 18 psi goes back up as i start driving engine was replaced which has i was told 180k miles oil pump that i took off was definitely worn out oil was definitely dirty like mud brown hints the quick fram filter and oil change but after i done all that pressure is good driving but come to a stop it drops i noticed with these engines the more they get worn out the less pressure they can produce due to worn out parts just cant keep up anymore its common for high mileage 4.8s truck runs great just had the little scare where the oil pressure low came on a couple times than i found the pump kit and redone it with fresh oil change i plan on getting another 4.8l completely freshen it from top to bottom swap it in and do the same with the motor imma pull out of the truck

There is a plug on the driver side of the engine on the side of the block it’ll be an 8 Allan key and you can manually check oil pressure from there with a manual gauge.
the cam bearing sliding out uncovers the oil passage, letting oil pressure bleed with out going between the bearing and the cam, it just bleeds back to the pan significantly dropping the oil pressure.
My 2003 4.8l has 178k cold start hovers just below 40 then once it gets to operating temp drops to 20-28 at idle drops to 5 or less and some times triggers the alarm. Soon as you rev it back up it jumps back up to the 28. I plan on doing the O-ring and pump at same time and will inspect cam bearings as well if I can see up into it enough to see if they have moved. It also needs an intake manifold gasket replaced too so not sure if a bad leak there could lower pressure or not, but plan on fixing that as well. At 178k I started to go ahead and just buy a reman engine, but I know these engines can easily make 300k or more so decided to try and fix it 1st.
So I had a broke lifter a huge piece was missing when I replaced the lifter drove fine for 2 weeks then had no oil pressure gave it sum gas then pressure went to normal do u think part of the lifter that broke is causing this
The barbell otherwise known as the dog bone is not a common problem. Generally its a problem after a rebuild when someone forgets to put it back in, or installs it wrong. There are a few other causes for low oil pressure but this video was made to cover the most common causes. Thanks for watching, I appreciate your time. Cheers!

@DIABLO_4_Tester_Sacramento 5 w 30 isn't really heavy enough on a 100 degree day, weight of oil is actually ambient temperature determined, if supercharge no where near enough, I run 10w30 in summer, 5w30 in the winter, synthetic Mobil one or penzoil is great synthetic also
If your observing low oil pressure and the lifters are not clattering or the main bearing rumbling, it's a indication issue. How ever, the screen under the oil pressure sender is a restrictor to the Vlom manifold. So if the vVom is lose, your leaking oil into the camshaft valley. and showing low pressure.
Great inf . I have a 2006 escalade 6.0 just hit 100k miles always maintained oil change at 3k always put mobil one synthetic end just last week I was driving on cluster it show low oil compression so I stop check all oils on engine everything was normal. Took it to a mechanic he suggest to change oil pressure sensor that didn’t work so he changed oil pump & he put new engine oil he did mention that there was metal debris on pan so he got it done nothing changed engine sounds normal no weird noises oil pressure is below 12 psi any suggestions?
I have the same issue with low oil pressure on my 2000 Chevy Silverado 1500. My mechanic said I need a new engine? I just need a second opinion. Please help🙏🏽
The screen at the rear of the engine is for the oil flowing to the DOD lifter solenoids AND lifters being kept clean! Oil Pressure sending unit just happens to be in the same galley to read engine oil pressure!
Hello, I have a 2004 gmc. .6.0 L. I replaced oil pump with pick tube. And still have a low pressure about 14 psi. What would my next problem?. When I step on gas pedal the pressure than goes up. Thxs
Cam bearings. I never knew those could be an issue until last week my tech told me he thinks that’s the issue. Low pressure, no metal in pan, ticking noise from motor, not lifters. He said he’s gonna need 4 hours to verify it’s the bearings. Can those be pushed back in or is this going to be a complete cam removal and bearing replacement? Is it worth doing the work and waiting for the next issue to occur?
@@claycardinal7253 it was the cam bearings. With 230,000 on the truck, I sold it and got a 2020 with the 5.3. I still think they are best motors out there. All brands, all motors have their own design flaws. At these motors won’t strand you somewhere in limp mode.
I have a 2019 Chevy Silverado. L. D and my oil pressure is down to about 30 and when I hit the gas, it goes up and then maintain the speed and it drops back down to 40.
I read the comments but my issue is different. I get 2-3 seconds of no oil pressure on first start of the day, after that it's 1 second to good pressure. I can hear the rockers when no oil pressure for 2-3 seconds (first start of the day). I suspect it's the cam bearings. I replaced them on this engine. (Wow they are tough to install). Came here hoping for a better fix but pressure sure one of my cam bearings has slipped. LS engines weakpoint is the cam bearings.
If you are installing cam bearings at home, I highly recommend put them in freezer to shrink them, if you have a cam bearing installer, do this trick they will not spin again
If its not the pump ring, the switch, filter or pump itself... there 3 things left haha its a headache. Possible cam bearing, posible cylinder deactivation solenoid gaskets and the last one... the lifters eventhough they might not make noise. You can see the lifter work after you remove valve cover and see if they are pissing to the wind.
I have a 2013 avalanche I replaced oil pump pickup oil sensor and have good oil pressure running down the freeway if I step on it really hard and back off oil pressure starts to fall put it in neutral turn off engine restart right away oil pressure comes back I guess the next step is to hook a pressure gauge to it and compare it to the gauge on the don't know what else to do.
get it checked with a manual gauge, if it is bad recheck the oring on the pickup tube (sometimes it gets pinched) other than that, start shopping for a rebuild kit or a replacement lol.

How low is low? Hot idle is normal to drop down to 25-30 psi. Did you replace the camshaft retainer plate? Very thin gasket there that if compressed and reused can leak oil and lose pressure. Also the valley cover has gaskets blocking off the dod oil galleys that can leak oil and lose pressure.

Oil pressure surges. Too high when engine is cold and too low when engins is warm. Has anyone solved this by changing the regulator/relief valve?I have changes the press sensor and screen. No difference.
As it ages it will harden and flatten and allow air into the pickup tube via venturi effect. That will aerate your oil causing all kind of problems including low oil pressure. Very very common issue.
@@walnutkraken9430 I never noticed anything on my dipstick. My main observable symptom was 20 PSI oil pressure - hot/cold - idle/3500 RPM made no difference - 20 PSI. Changed the o-ring and 50 psi cold idle/30 psi hot with pressure rising with rpm to about 50 psi 3500 rpm hot. That aeration (about 3 months) did cause a lifter ticking issue that I had to replace the lifters. If you catch it soon enough most lifter ticking will go away once replaced.
