This is the ONE video that needs to be seen before people start throwing parts at cars. great job my friend.
Nava TheBitch Thanks 🙏🏼Means a lot, let’s hope RUclips hears you 😎
This is the kind of mechanic i need. He could have changed the switch to get the money as some mechanics would. By word of mouth, his honesty should bring him more business than he can handle so he doesn't have to be greedy.
Thanks, appreciate that 🤝
@@HomieHektor I have a chevy silverado V8 4.8 it tick 3 to 4 minutes after starting. 15 to 20 minutes later it stops. After that it runs extremely quiet. Until I let cool down it won't tick. Do you think it's my exhaust manifold bolt?
Hello, I recommend the Phoenix Elite from Topdon to you. I am also using it, and I think it is very good. The functions and coverage of the models are very complete.
Here is a video of me using this device to reset the engine Oil Light for the 2016 GM Suburban: ruclips.net/video/M_4W8pUm6_0/видео.html , you can refer to it, maybe it will help you!
Sup Hektor. It looks like you are a honest mechanic😉 Over here in San Jose is hard to find a honest mechanic.
Keep up the good work 👍
Rodin Ramos Thanks 🙏🏼
Always Something Simple, Great Job HomieHektor.
True 👍🏼
best tip ever, simple yet effective!!
David people tend to forget about the basics, but it’s really that simple.
Im just a 56 year old farm mechanic but thought id share this tip. When you are having a hard time seeing the oil on a dipstick you can sprinkle baby powder on the dry dipstick and shake off any access. Then recheck the level and you will have a very accurate view.
Great video keep it up. He has a piston ring issue but with that mileage his lifters will fail most likely soon.
You don’t know nothing! Left valve cover need to be change for oil consumption
If it's ~ 30 PSI at a cold start (overnight cooling) and then you find that the pressure is around 0 to 10 psi @ idle after about 10 miles of driving (such as when the engine is running but you're at a stop light), you'll need to change the oil pickup tube o-ring. It's sucking air/not pumping the necessary oil because of a bad seal/busted/stretched-resized o-ring. In this case, the oil pressure "low" warning is REAL - and you need to fix it ASAP.
Provided your instrument cluster gauge is working correctly - and your oil pressure sensor is working correctly - and your wiring/ECM is not screwed up/busted, the general procedure (after raising/supporting the vehicle) is:
1) Drop the front differential/axle.
2) Take off the oil pan bolts (including the super-long ones where it meets up with the transmission) along with the oil pan itself. If the oil pan gasket has never been replaced you'll need to drill out the rivets which keep it attached (or risk re-using it and discovering a leak at some point in the near future).
3) Remove three bolts mounting the pickup tube / suction screen.
4) Remove the bolt holding the pickup tube into the oil pump intake tube.
5) Remove the stale, malformed, out-of-round orange/red-ish colored o-ring on the oil pickup tube.
6) Replace the o-ring with an OEM or high quality/perfectly spec'd NEW o-ring (aside from new oil and a new oil filter, here's the big $$ part of the job...it'll cost you a total of ~3 to 4 bucks).
7) Re-install the pickup tube assembly and bolts.
8) Put everything back together in reverse order, making sure to use gasket sealer around the points where the oil pan meets up with the transmission.
(I think those are all the steps...but do your own research to be certain)
If you do all this and still observe super-low oil pressure, you've got some potentially serious internal problems with your engine. This could (at the lower-cost end of the problems) be a bad oil pump. At the higher-cost end of potential problems, you're looking at blocked oil passages inside the engine...such as sludge because you didn't change your oil for 15,000 miles. You could even be looking at blown-out/damaged crank shaft journals. It could be a lot of things...and they aren't cheap to fix.
With the engine running, if there are NO tick-tick-tick sounds coming from under your valve covers (e.g., lifter knock), and you found no metal pieces in your oil pan during disassembly, I'd suggest you didn't have enough oil, you had the WRONG oil, or you had a coolant/oil combo in the system, or you didn't properly diagnose the problem before undertaking the o-ring fix.
I had a code for oil pressure switch come on two days after white smoke comes from the exhaust on start up but goes away after starting it. I have a tick on the driver side and I assumed it was the exhaust manifold. Then the engine light came on and it is for the pressure switch. Any thoughts what could be wrong other than the oil pressure switch ?
There are no signs of a blown head gasket (no milky oil/temps are normal). The truck is a 2009 5.3 and is used to tow a 3500 lb camper. Oil was changed less than 5k ago but I noticed it was low and added about 2 qts to get it back up to normal levels. There are no signs of an external oil leak to cause that much oil to be missing unless towing really does burn that much oil?
I see this alot some cars have oil leaks others show no visible leaks and when I talk to the car owner alot of them never check their oil they have it changed when it's time some manufactured say a certain amount of oil lose is the way the engine operates so I show them how to check their oil and explain how important it is to do so I'll even write down what oil to put in if they need some on the airbox with a paint pen but some cars don't have dipstick which is stupid if it's a workable fluid it needs to be checked
He quiero felicitar por tu honestidad, otros techs recomendarian la oil pump, oil pressure switch , y otras partes relacionadas con ese codigo, gracias un saludo #chingadera,
i have the same issue , so you only changed the oil and the oil filter!?
Would this cause a loss of power?
Valve cover is plugged. And the screen is plugged below oil pressure switch.
Yo bro I have a check engine light on my 2015 duramax any idea what to do?
Where are you located at bro what shop?
Or in my experience Firestone didn't put enough oil in it last oil change!
David Taylor On behalf of Firestone...I apologize 😁
Question also could be if it was filled to proper level
Sir Sweetness That crosses my mind 🤔
😘 thanks
HELP PLEASE.. I got 40 psi start up cold idle. Warmed up I got 20psi idle and 30 psi driving. I have changed oil and it's full and I have changed the pressure switch and screen. Had dealer do the work and manual check shows 60 psi pump pressure. Problem is even at 40 psi gage pressure my check engine light comes on and scan shows PO521 oil pressure switch. I also used seafoam to flush engine still get 40 psi cold and 20 psi warm with 30 psi warm driving and check engine still coming on after clearing it and at 40 psi gage pressure.Any suggestions as to what could be problem.
Any update? My oil pressure reads low 20s but I’m getting the p0521 code ?
I have a 2007 chevy suburban and I am lucky if i get 50% out of an oil change. It's a known issue with this engine burning oil.
Since when ? I’ve owned 2 5.3s and a 4.8, and none of them have ever burned oil . You most likely need to do the pan gasket
@@levicallis459 Google it. They are trying to sue for the 2010-2014 as well.

Changed my oil is all it took for my check engine light to stay off. Dash said I had 45% oil life left. It was wrong.
What would make the engine light come on while driving and all gages were all where they are supposed to be at. Also has enough oil in it
There is no Oil Level instrument on these motors, only a dip stick. The oil pump discharge pressure will drop with a low level & the pressure switch is factory tuned to compensate for viscosity & temperature fluctuations.
Hope you can help me with y duramax 6.6 2003
My goodness, what happened to an owner checking under the hood once in a while? But I get it. Not everyone thinks about it because we've become so spoiled with technology. The 100,000 mile spark plug change and the 10,000 mile oil change gimmicks the sales people lure us into has made us lazy.
wyattoneable 💯% Agree 🤙🏼
Possible shop didn't fill it up. Happened to my daughter, got hers changed I check it 2 weeks later, barely any oil.
I had two codes. Changed all my spark plugs to fix one code. Now I have this code. I'm thinking I just need to change the oil. Have about 130,000 miles on my silverado and I don't plan on selling it ever.
I’m having the same issue on my 2010 Silverado, a p0300 code and this one.
@@THREEPOlNTERS I changed my oil and it went away hasn't came back since.
GMC service didn't get his filter tight!
Wouldn't that be the first thing you check before you do anything?
Yeah I agree . If you’re aware enough that your switch might be bad , then you most likely know what your oils at
Replacing the oil switch/sensor will avoid a come back an assure you of a better fix. Remember there is a small filter below the switch internal to the engine that get clogged that needs to be replace also. Just an advise..
David Tellez absolutely agree, did you see how dirty that oil was? I’ll keep you guys updated, but for now it’s fixed 🤙🏼
Wow!!! Some people's kids lol!! Gee can't imagine why that oil pressure would be running so low!! 🤦♀️🤦♀️🤦♀️ They're lucky they didn't blow their motor driving with no oil... omg smh
I had this issues today same truck and Year
Abut checking it with gage
I put a new sensor and the pressure is only slightly better, but I’m realizing it wasn’t a oem sensor just some autozone sensor.
Should I try a oem sensor ?
Hey, I also used generic sensor, it failed in no time. Needle would jump around, show low pressure, eventually constant dinging/warning. Replaced with GM.
And I can check the oil with a scan tool but the ordinary car owner can't so if your car by manufacturer can loose up to a qaurt of oil every thousand miles then in a 5 thousand miles oil change you are out of oil or so low it's killing your engine
Link for that scanner?

Hey you look like che guevara
Im like #666!!!
GM cars have a lot of oil leak
You didn’t fix anything man!!! U have a oil lost! Possible oil leak or a the pcv which is incorporated on the valve cover, very common issue! U can’t just let the customer go knowing it had oil lost
bang on !! .......dude did nothing other than finding the truck had no oil which a 5-year-old could have figured out ...L want my money back!!
Code 446
2010 scion xb 1/4. Oil loss every 2weeks
Reason unknown common with xb’s
And toyota warrantee only 3yrs or 30,00 miles 👎🏼
My vehicle is riding aroubd 15lb aswell literally identical to the oil pressure in this video however it is full of oil.
