2007 GMC Yukon 5.3L with Low OIL Pressure/STOP Engine Warning Message 🛠🧰😬 

Change the screen under the sending unit located on the back of your intake. If its not knocking its lieing. Also change the o-ring on the pick up tube in the pan. Use ac-delco filters only. Do not listen to anyone who says different. Fram wix "auto store specials" are not gm approved and will cause lower oil pressure. Run seafoam in your engine 50 miles before a oil change. Run for about 100 miles and do another one. Leave 1 qt of oil out and add a 1qt of atf run until your next oil change. IF none of that helps then replace oil pump. My 2012 burban loved to pull the no oil pressure trick right before its oil change. 20psi at idle and barely 40 at 70mph. Now its 40 at idle and around 58 at highway speeds.

If its a 6qt oil capacity use 2qt atf and 4qt oil . Perfectly safe way to flush motor and works great , atf is very strong detergent and wont harm any gaskets or seals

Hey Aaron 👋 I called my neighbor who is a chevy mechanic at a dealership. But he's drunk can't understand a word he is saying . He is celebrating his birthday. All I could understand was make sure its the big oil filter not the small filter. If it was the oil pump would you not hear knocking . I'm no mechanic just a farmer. Have a good night

You must’ve done a lotta mechanical stuff when you were younger, you know a lot more than the average rancher

Hello, happy new year

Did you get it figured out? We have the same issue with our Yukon.

It’s your oil pick up tube O-ring.. you have to drop the oil pan to get to it. Yours is either cracked or flattened. There’s some labor involved but the ring itself is only a few dollars.

As far as oil goes in the cars, I like Mobil 1, Valvoline, Supertech seems fine and is easy on the pocketbook. 😉

Oil uptake tube o ring or stuck pressure bypass plunger on the oil pump.

May need to change the pickup in the pan. Sort of big job but Take pan off and fix the leak and cleanpick up screen

Another way my dad used was transmission fluid and run it for about a mile with engine hot. the fluid has detergent. Best way is to run Mobil 1or Castrol Syntec Synthetic oil you will have no oil issues

I use 5w30 valvoline maxlife syn blend for my fords 5.4L and 4.6L

Well at least you got the old gas /oil outa it .. which is a good start.. my next step if were me, be to change out the pressure switch.. doesn’t matter if ya changed it not to long ago.. some of those can be cheap junk an take nothing for them to go bad .. also what ever screen your talking about , clean that too .. if still there after that, id take to shop /garage let them diagnose .. then decide if you wanna fix or let them.. maybe its an oil pump problem.. it starts an runs good an no lower rod bearing or crank bearing noise at all anyways good luck 🤞

I've used the transmission fluid before works great put it in let run for 10-15 minutes . Do an oil change run it for about 100 miles do another change. Learned from a mechanic he had 40 years experience.

Removing oil pressure sensor filter: insert a rifle cleaning brush. say about .223 caliber iknto the pressure sensor hole and remove filter. Poof there it is stuck to the bristles of the cleaning brush with no damage. Judd Lewis

Take the oil pressure gauge out and clean

Since you collapsed a oil filter earlier, I suspicion something bigger is going on. I don’t think it’s electrical anymore either since it went up with new oil. Screen?? Oil pump??? But I’m no mechanic. It’d be at a garage already. Lol 😂 .

I have a friend with this same motor in his truck and apparently it’s got this issue all the time apparently there’s a screen under the oil psi sending unit that needs to be cleaned every oil change he says

First 1st 🥇

Yep check that screen.

Oh man i hope it’s just a sensor or something. if not part out will make you somey good money.

I have the fix for you...5lbs of tannerite ...cheers buddy 🍻🍻🍻

I had a 2007 yukon 5.3 I had the same low pressure problem,and i changed O ring,screen behind the engine etc. Didn't work! The problem were the lifters,after an expensive fix I sold it,I'll never buy a GM product again

If oil pressure is jumping around change the sensor.

Those f…ckin Chevys you can’t kill them😆 i don’t know 🤷‍♂️ what’s wrong with it lol

Looks like the symptoms of the bad o-ring on top of the oil pump. Time for a new melling high pressure standard volume oil pump while you are in there, replacing that o-ring. They are not that hard to change. Plenty of videos on RU-vid.

So what was the issue

How many 🥃🥃🥃🥃🥃 does it take to buy a Gm product? Lol. I don’t know if I could get that drunk anymore. 🤔🥴🤷‍♂️

That truck runs and starts too good to actually have shitty oil pressure

Check for a leaky injector. Maybe have them cleaned?

The oil sending unit / preasure switch maybe weak or just cheap junk

Can you get to the point. Come on here looking for help not all the extra commentary 🤦
