well, I was ready to take my 2001 Chevy Silverado to the workshop to have the oil pump changed, my truck had zero oil pressure every day in the morning and after driving it for about 30 minutes it went up to 40, after seeing Your video came with my mechanic and I asked him to do that specific procedure, the cost was $ 260 including parts and labor, now the oil pressure is 40 when turning on and when driving rises above 60 or more, the noise of The lifters are gone, the engine works very still and silent I am very grateful to you, God bless you.
Daniel Neria I’m glad this fixed your issue. Thanks for watching as well
@@OzMechanics what kind of O-ring do you recommend?
Marcos Torres
Go on parts geek and look for an o ring that fits your vehicle 🚗

@@Rea1_Madrid thank you very much!!
It just started getting cold where i live. My 01 5.3 is doing the same thing as yours. Time to tear it apart I guess
I changed the engine oil in my 2013 GMC Sierra a week ago. I've had this truck for over two years and have grown accustomed to where the oil pressure guage rests throughout the warming cycle and normal operation.
This time I used the usual Pennzoil 5W-30 Platinum Full Synthetic along with a new-to-me ACDelco PF48E filter that was available locally. I usually have a couple Wix 57060XP on the shelf but had run out and couldn't find one locally.
I drove to work the next day and at the first traffic signal I noticed my oil pressure guage reading a bit lower than usual. The truck is usually at 30-35 PSI idling in drive and 40-45 driving at 1.5k-2k RPM. But now it was 18-20 PSI idling and 22-26 PSI while driving.
I started watching YT videos trying to diagnose the oil pressure issue myself. I added a drop of Lucas Oil Stabilizer, no change.
I dropped the oil pan (pain in the rear) and changed the fabled o-ring, no change.
I bought a new oil sending unit. Before replacing that I decided to pause and ask...
WHAT CHANGED?
AHH. The oil filter was a different brand. Maybe that's it?!
This morning I climbed under the truck with a drain pan and swapped out the brand new ACDelco PH48E with a brand new Wix 57060XP filter. Topped off the oil and started the truck up.
Dog gone it! The truck was BACK to the normal oil pressure readings of 30 - 45 PSI.
I don't know if the new ACD PF48E had a bad check valve or the media was too restrictive...
Fellers, if you find yourself parts-cannoning after a similar situation stop first and ask yourself: WHAT CHANGED?
I'm relieved that my truck isn't busted and it was a simple oversight.
I hope this helps someone out there.
I have a 2010 tahoe that I just bought with 176k miles on it. Ran perfectly. I had about 500 miles on it and one day I was driving it to work and lost almost all oil pressure. Lights and sounder going off telling me to shut the engine off. Well I limped it home, prayed and it didn't appear to be the oil pressure sensor as it was moving up and down in proportion to rpms. So I'm like. Well I haven't done an oil change in it myself and it was due. Did the oil change with mobil1 and a quality filter and my pressure went from barely above zero to 40 psi at idle. Drove it for an hour after that and it ran at 40 psi around 1600 rpm. I'm like was it the filter. I think it was!
IVE HEARD ITS THE FILTER. I NORMALLY GO TO THE DEALERSHIP FOR THE OIL CHANGES BUT I WILL DO THE NEXT ONE MYSELF AND USE A WIX FILTER. IVE ALREADY CHANGED THE SENSOR
Excellent tip! Great video. It worked perfectly. My 05 GMC, with 315,000 miles, now has more oil pressure than ever before. It also silenced the lifters which I was fully expecting to change. I think I'm good for another 100,000. Thanks!
Love to hear it🎉
I'm glad I read your comment. My 4.8 is making a lot of noise. It's making that "ticking" noise. I think I need to do this before I go messing with the heads. Thanks
This finally fixed my 2010 GMC Sierra after changing the oil pressure sender 3 times in 5 years. Thank you! No more tapping when the engine is cold either!
Maybe ill do mine. 230k, just did lifters and the filter under the pressure sender. Idles at around 18psi
My 2010 5.3 has 183,000.I changed the sending unit last year but didn't change the screen under it.I just had to change it again,this time changed the screen too.Mine is a 4x4,hope I dont have to do this.
What engine you have in the gmc?

I have a problem with my old when it gets hot it loses my old pressure and I checked the old pump and I checked the crank Berry and I don't know what it is I would like to know what it could be it's on the S1095 Chevrolet I asked somebody to contact me and let me know if they can tell me what it is it's an engine's been revealed it would blow up rebuilt the engine and the block looked good when he rebuilt it but now we got it apart and we just don't know
Good information, thanks for actually taking pick up tube out and showing us the o ring was still complete but brittle. One thing to keep in mind in this two wheel drive chevy it was easy to take off the oil pan, in a four wheel drive it would be a longer task since would have to lower differential.
Thank you very much from Russia. It helped me, Chevrolet Express 1500, mileage 480000 km. oil pressure is normal.
I JUST HAD MINE DONE. WOW WHAT A DIFFERENCE, THE ENGINE IS SO QUIET NOW AND ALSO WE CLEANED THE OIL PAN AND PICKUP TUBE FILTER.
Ant Avil good the hear
How much was it?
Thanks so much for posting this video! My oil pressure in my 2012 Tahoe was idling between 18 & 20 and sometimes down to 10. It would go up to 40 if you hammered the gas or when it first started but then back down to 20 or less. We tried replacing the oil pressure sensor first with no change. So we found this video and gave it a shot. Our o-ring didnt look near as bad as the one in the video. However, it was a lot less pliable then the new one. And it did snap in half after messing with it for a bit and we could see it was starting to dry rot. Needless to say, we replaced it and my oil pressure idles just below 40 like when we bought it. When accelerating, it gets bup above 60. It is running so much better! Again, thank you for sharing this!!
glad this video helped out

Oz Mechanics DID YOU HAVE TO DROP FRONT END?
Oz Mechanics I have a question for you if you would be able to answer it. I have an 03 Silverado with a 5.3 the oil pressure goes up and down. When it goes down the motor knocks when it goes up the motor stops knocking are you saying my pump isn’t bad and it could be this little o ring thanks in advance
My 2007 Silverado 5.3L, 300k was having a loud popping noise when cold and whistled. Then oil pressure gauge ding-ding warning! "Low oil pressure, turn engine off". Mechanic replaced deteriorated O-ring on the oil pick-up tube at the oil pump. So far, so good. No Jiffy-Pop!🙏
I change the oring on my 2013 chevy silverado , I was scary because the old oring looks good to me but big difference wen put everything back the pressure oil its 35 to 50 thanks to this video 👍🏼
The first time this happened to my truck I was taken to the cleaners. I spent $2500 for new lifters, seals etc. Probably needed it though as I was pushing 150k. Almost three years later it started dropping again today - It would slam to zero not just when I stopped but when I was driving - with low oil pressure light coming on telling me to shut engine off. (2007 Silverado 5.3 Z71 LTZ - NBS). I pulled the oil pressure sensor out, then pulled the small filter out underneath it. Cleaned it up, put it back in with same sensor and its been good ever since.
How dirty was the filter ?
The top half was ok. It was the bottom half of the filter that was dirty and was clogging the filter. I wonder if you could get away with completely removing the small filter all together?
@@OzMechanics what is the part called , just an O ring? Where can I get the part and hats the proper name so I can get it from dealer
I just found the o ring you can get at auto zone it called oil pump inlet tube just 3.49 very cheap good luck
Cool thanks
Thanks for taking the time and posting this, I've been so frustrated with my Silverado.
When I change the orings now I started smearing silicone in and around the pipe joint as well, but on my own truck I used JB weld. It wont ever leak.
Don Rutter 😂
This could be your problem indeed but if you want to be safe before going threw all this work I suggest checking your oil pressure sensor and filter. The filter is under the sensor In the same hole just stick something with a curved point in there, puncture the screen and remove. Put in a new one and check it out. The sensor is like 50 the filter is 5. Tools needed are 1 1/16 deep week socket, swivel adapter, extension and rachet. 30 mins tops
He literally said "in last video changed sensor"
Straight forward with the issue on this engine, I like that because no one likes to actually fix this years 5.3s
Just did this job a few months ago. The o ring gasket was still ok but the pickup tube was clogged. Cleared it and replaced the o ring just for the hell of it and it solved the problem
A temp fix is to add some AT-205 reseal to swell up the o-ring and give it better oil pressure. My 5.3 had loud tick and knock, after adding some reseal to oil the knock and tick is gone. This temporary fix will allow me to save up some money to have oil pan gasket and o ring replaced.
Yes but its NOT temporary! At205 does not ‘swell’ gaskets, it rejuvenates them.
Excellent video, what a strange design. Engineers had to know this would be an issue, I wonder why they crossed the line and made it anyway. And I wonder how many cars died before diagnosis.
I was losing a quart of oil a day on my Ford van (3 speed clutch).
I put one can of rear main seal stop leak in it, and complained to NAPA the product was junk. (Smelled like vodka too).
He said it always takes two of them. So I put another one in.
It worked. It never leaked again. It softens and expands old rubber parts without taking anything apart.
rapturous day yea the (snake oils ) tend to work sometimes. But in the end of the day it’s basically a bandaid. Hope it last I had a customer that put the head sealer and it lasted a good 2 1/2 yrs
Thanks bro. My chevy tahoe was sounding like a freaking desil. I changed the o ring and sounds great now. Thanks to your advice.
Lezz Love no problem. Glad this video helped out
I appreciate the video. I think you just saved me a lot of time and money. My 4.8 is making a "ticking" noise. I was going to pull my heads off and start changing parts but i think I'll try this first before i do anything drastic. It only has 220,000 miles on it so I don't think it's ready for rebuild yet. I want to get every last mile out of this motor.
Awesome. Let me know what happens please
@@OzMechanics I definitely will. I'm too broke right now to change my oil and replace the o-ring on the pick up tube. I'll let you know as soon as this white privilege thing kicks in and I can actually afford it. Jk I'm done waiting for that shit. I'll let you know as soon as I can get it done. Thanks again for the video.
Thanks for the info. Before doing that procedure, I recommend removing the Oil Sensor and be sure the screen beneath it is clean. Then check to see if that cures the problem. Cheap Oil Change places also use an inferior filter that voids warranty I am told. Only GM filters can be used on Engine and Tranny to maintain Warranty coverage.
Gord Baker that is 100 % true. I had one that was completely clogged luckily that was the first thing I looked for
I have an 09 , 5.3L in my truck with about 150 k on her and so far so good
To help diagnose this issue you could and a few extra quarts of oil and park the truck on a hill noise down so the “hole” in the pick up would be under the oil level.
If this is the problem with my avalanche, I love you so much!!!
Keep me informed
2$ o-ring damaging 5k engine.
Eye opening video.
Thx
1-7-18... Video was straight to the point. Thumbs Up. 👍👍👍. Not like bs from masterautotech1. Keep up the great work, bro.
I think this is solution to the exact problem I'm having! Thanks pal!
wow super cool makes sense, great stray analogy. My Suburban was on 0 pressure, but after I changed the oil (truck was sitting for 2 years) and put some lucas in it, the knocking stopped on lifters and pressure was restored.
Thanks man, I'm having the same problem so I think that's what I will have to do with my truck
Did you ever fix the problem
Was it?
??? Any feed back?
Thanks for the video. I have a 2010 Chevy Silverado that started dinging and low oil pressure flashing so I replaced the sending unit and it was fine for a week but doing the same thing now. I just turned 200 thousand miles so I'm gonna go ahead and replace the oil pump to.
There is a small plastic screen under your sending unit that gets plugged.clean it or replace it
I have good oil pressure while cool engine but after in warms up and I come to idle my gauge for pressure will drop low and my light comes on and then will flicker on and off. No knocks or noises, can you tell me maybe why. I just changed my oil pressure sending unit as well.
I have this same issue now with my truck. Guess i gotta get the orings changed
Hi I am get a check gauge light on my 98 oldsmobile bravada the oil gauge go up in down what can I it be can point me to the problem , thanks hope that you can help
air bubbles I oil from loose o ring can cause lifter noise or wipe out bearings also.
Thanks In will check this. I have a few 5.3with over 250k no probs yet .
I have a 07 yukon that's doing this now im putting a high flow oil pump in it this helped a lot
Awesome. Glad to hear
Me and a few friends replaced my pickup tube with this o ring and my oil pump on my 06 Silverado 5.3 with 140k miles. The o ring was just as bad as this. In fact it was oval when you looked at it from the side after it broke when I took it off just like in this video. When we took the timing cover off to access the oil pump we noticed two bolts had backed out of the oil pump on the side that feeds the engine and were not even touching the oil pump! My oil pressure after we fixed these issues went from 8 psi @ idle @ operating temp to roughly 35-40 psi. This information was a huge help. I would recommend changing the oil pump if your going to change the pickup tube. It took about 10 hrs with 3 people. I would also recommend extensive research before doing this job. Do your homework!! Thank you!!!!!
The guy from America that is 100%. Doing your homework it’s the key
I think I'm having a problem with this. Mine is a 2004. Oil pressure is fine when I first started up in the morning but it slowly loses pressure as I drive. Cutting the motor off and turning it back on helps for a little bit.
Love to see the whole process
Just did this. It's holding 50 lbs at idle now. Thanks
Good to hear this
i thought you were going to say something extremely very stupid and wrong with the straw analogy; but u pulled through, good job!
Yea the straw analogy was the one that crossed my mind. Made sense
@@OzMechanics i got a quick question for you, 2008 gmc savana 3500 4.8l 200k.... Low oil pressure starting (close to none) until it gets warmed up (30 min).... One: do you think this is probably the issue? Two: is it a pain to access/remove my oil pan? It's rear wheel drive.
Mitchell Wood I would start off with the oil sensor screen on those vehicles. Some get clogged up
@@OzMechanics thanks for reply. will do first.
Oz Mechanics Could this be the problem on my 2013 Silverado? The oil pressure never stays at 40 it always goes below especially after the engine warms up. Just recently I had a code pop up saying the oil pressure sensor was bad. I already replaced the sensor and the little filter inside where the sensor goes, but my oil pressure is still fluctuating and I’ve noticed it gets pretty close to 0.
Thanks for this info! Just picked up my 06 tahoe from body shop and didn't get 2 miles before oil pressure dropped to zero and warning alarm goes off. Pulled over right away and cut off. Oil level ok, started back up and was at 40 again then within a minute started dropping right away. Had it towed to shop but trying to be informed before they look at it tomorrow. Normal lifter noise you hear when cold, esp if not running synthetic but other than that no issues. Hoping it's something like this.
what did you ultimately have to do?
Thanks for this video bro. I am having low pressure problem and think this could be it
I Had the same problem with my 01 tahoe, you're right that will be the issue
thanx for the advice im trying the pressure sensor first if not. that will be my next step nice video bro
Many times the oil pressure gauge either doesn't work or has a low number usually means the sensor is leaking w/o actually having to look at it.
I did the seal on my truck this week 100% accurate fixed the problem for everybody else that has an oil pump issues you probably waited too long to fix it.
Just dropped my oil pan and pulled the pickup tube in a 5.3L Suburban, which just dropped out with no resistance (the pickup tube) as you show in your vid. Mine had a green o-ring in it that had, just a very slight, nick (1/6") taken out of the inside diameter. The o-ring was still malleable, even after 150K+ miles. This rig was having intermittent loss of oil pressure warnings. The warning occurred on cold start when the outside air temp dropped below freezing and on cold days when the rig was stopped on a hill.
A local repair shop wanted to rebuild the engine, but that didn't seem right, even though I trust that shop. After doing some research I discovered there was a "service bulletin" put out by GM for this o-ring (#02-06-01-038 - (Dec 2, 2002)) about this issue. The service bulletin revealed this o-ring may have had a small "cut" that could create problems early in the engines life. Well, this rig started having problems in more extreme conditions later in its life, due to this cut in the oil pickup tube o-ring.
Thanks for taking the time to make this video 🙏
Bad piston rod bearings caused my low oil pressure. On my older ford I had a backyard mechanic guy put in new lower rod bearing, oil pressure jumped right up.
It was loud as hell at first because the air was still stuck in the hydraulic lifters.
I have 2 2001 suburbans. One lost total oil pressure on the interstate and locked it up. My other one has lower than usual pressure. I think i will check this out.
I have a 2014 Tahoe with almost 300,000 miles in it. Never had a problem until recently. The oil pressure hardly ever gets over 30 psi and most of the time it just stays at 20. Could this he the problem or is it something else?
08 Chevy Silverado 1500 5.3 low oil pressure when I start up but later it Smoove’s out but continues to go up and down but my lifters starting to tick as well I was told the same procedures you just showed would fix my problems.
Great video and info! Thumbs up as always!

Did you Get it fixed?
@@tipsreviews7476 yes sir I did once I replaced the O ring it fixed the problem. The O ring was literally like paper and ripped as soon as I touched it. Oil pressure did not stabilize right away though, it took me driving a few miles before I started to see the oil gauge move to the middle position. I’ve noticed it takes a while to stabilize after cold start, oil gauge moves up and down but after driving and at a stop position the gauge stays in normal range.
@@tipsreviews7476 forgot to mention that by doing this it also silenced the lifters witch I was considering changing before I replaced the O ring.
Thanks for the info. I have to keeps an eye on my oil pressure it's drops to 25-30 is that normal range?
Drops to 25 to 30 while operating temp at stops. Goes up to 40 while driving.
I need to replace the olive green one that GM fitted into my LS1 engine in 2002 with this one Holden sells as default :- 12557752
It is a light blue coloured one,I know GM had issues with them splitting in their Gen III onwards V8 engines even from the factory.
Mine isn't split but I am doing a Hydraulic lifter change & I've replaced the timing chain so I had to remove the oil pump.
I didn't drop the sump ,I just removed the timing cover & oil pump,it is a bit tricky but.
I think that GM must've revised the o ring as I mentioned they have had troubles with them splitting particularly when they are too big.
Other ? I have is if he put 10/30 5 qts. And 1 qt of Lucas in it would that be any reason for low oil pressure light and 0 on the gauge it doesn’t move at all yet runs and sounds fine . ??
Straight to the point. Thanks!
I have a Vortec 4.8L V8 truck. It runs good - but when idling (like parked in a fast food drive through) for a while the engine(lifters?) start ticking. Then I start driving again the clicking goes away. Is this an Oil Pressure issue? Thanks.
Wyatt Sexton Either your oil pump is going out or you need to up the Viscosity of your motor oil. If it calls for 5w30 then go to 10w40. The oil is thicker and won’t hurt a damn thing! Especially if the vehicle has a lot of miles on it!
Great video man. I'm trying to decide if I should replace the sending unit and don't know if 2006 5.3 Silverado LS has a filter under the sending unit or not! The shop gave me a rough estimate for replacing oil pump, sending unit and o-ring for 700-1000 dollars. I'm 67 with back issues and I think that's a fair price but on social security it's a lot of money. I'm going to look things over and see if I can replace sending unit and try that.
Loved it - Thank you! It would be awesome if you could also add the sparepart number. We are talking glazing, but since you've already made the cake....
I have a 2010 suburban and the light came on, low oil pressure don't drive. I will try this. But I have P0302, P0303, P0304, and P0308. Have any idea what that could be? I changed the injectors for those cylinders and that did not fix the issue. I will be changing plugs and checking coil packs tomorrow. But you seem knowledgeable and thought I would ask is that no other video channel even answers the posts at all. Battling throat cancer and bills are killing me. I need my car to get to doctors or might be the death of me.
Pyde Piper sorry to hear what’s going on with you. For the low oil pressure, does the pressure stay all the way down when the light comes on ? Or those it go up with higher rpm’s ? As for the misfires that’s a hard one to check. I would look at fuel trims to see that. But you would need a scan tool for that
@@OzMechanics I will check today. I know that the fuse box got wet and caused alpt of electric parts including the starter to go bad. So it's not normal. I now know it's not the injectors. I knew it couldn't be 4 going bad at the same time.
So....I knew about this problem, thought it might be awhile before I saw it in the 05 Yukon XL I bought about 4 months ago, I've been dealing with a myriad of other sleeper issues popping up with the truck...pressure was holding pretty steady ever since I got the it at around 25-30 idling and 40+ at my usual 2-3k rpm with the thing cruising around the city like I do...today though (it would have to be on a Sunday) I got up and my usual run to the store and saw my first sporadic dip to around 10-15. How long do I have? Can I douse the thing up to its max fill level and hope to make it to my office meeting tomorrow and then to the GMC dealership after work? Also, once I actually get the O-Ring, can I pull the pickup tube off with the oil pan or do I have to pull the balancer and front cover off as well?
Glad my 02 Blazer doesn't have this o ring. Still strong after all those miles.
excellent HONEST video! thank you
Question, with high mileage oil with additives to “swell” up seals, is it possible it would “swell” up this o-ring to?
I wonder if this is the problem with my 2011 Tahoe 5.3L. The pressure sensor and screen are new, but oil pressure still reads too low. Haven't gotten a warning/beep about it yet, but it makes me nervous. I got this truck about a week ago and I love it, so I don't want to ruin the engine. Should I stop driving it until it gets looked at?
Did you fix it?
Thanks for your service
How many miles was on this engine, got a cold lifter tick for about 10 minutes only on cold mornings, my buddies truck just started to do it to.. both at around 200k miles..
Would that cause a misfire and light tap as well along with the low oil pressure?
At work we use Lucas and it helped for a wiel . I kind of wondered if it might be the oil sump coming apart but i was just gessing
excellent! had same issue.
i have 2 pickups with 5.3 in them both have very small oil filters when the oil pressure drops before oil changes are due i change the oil filter put in a new one and the oil pressure go's back up to where it belongs do you no why that is?
I have in issue with my 2012 GMC Sierra it hasn’t been reading oil pressure for almost 2 years & I changed my oil sensor around thanksgiving this year and it was reading fine then out of nowhere it stopped reading oil pressure and now I don’t know what it could be now people tell me is the oil pump but my truck is running fine I haven’t heard any tucking or knocking hope you can help me out ! I would really appreciate it
I had the pressure switch replaced because it was showing below 40 psi (maybe in the 20s) but that was back in August and now I started noticing the pressure needle indicator sometimes fluctuates erratically from min to max but super very fast....like a lie detector needle.
My oil pressure is good on start up, but goes to zero when warmed up. It bounces from zero to 60 lbs. Most would say it's the sending unit, but I changed it about 18 months ago. Should I change it again?
I just want your opinion if this would be the solution if a 2017 gmc 1500 Sierra 5.3 with 70,000 miles has oil pressure under 40 ?
Your an excellent mechanic but I would like to see start to finish. It can't help me or others if that doesn't happen.
What's the part number or how to see if I get the right one ring? I have a 2004 2wheel 5.3
I have this issue will it cause a p3400 code? Cylinder deactivation bank 1
Hi, we have a 2004 yukon, 5.3, 235,000 miles, oil press drops to about 5-10 at idle, at 35-40 mph it goes up to about 25-30psi, replaced oil press. sending unit, no help. Hook up manual gauge to sensor hole? Assuming same reading with manual gauge I'll tackle the o- ring.
I removed the oil Pan and changed the O ring and cleaned the pick up screen and still no help. The O ring was still very flexible and not all brittle and broken. Going to tackle the oil pump today. The oil Pan had very little if any sludge in the bottom of it which is encouraging.
My O-ring was flexible, but it was flattened. Replacing it worked for me. But I seen another video what are the pressure plunger in the oil pump becoming stuck can cause oil to flow back to the return which can drop your oil pressure significantly.
Have a 07 silverado Lh6 5.3 oil pressure is good if rpms are up .at idle oil pressure drops and starts ticking
I just bought a 5.3L out of a 2006 truck and they claimed it only had 3psi of oil pressure but wasnt ticking or making any noise. It only has 67k miles on it too. Could it possibly be the pickup O-ring too?
My truck is doing the same thing..... but due to lack of funds i havent done a oil change in about 1 yr..... does that has to do with the la k of pressure or it may be that oil ring???.... thanks for your time
Tried the other stuff on my 07 not sure if I have the same problem, about 30 lbs at start up but as it warms up oil pressure drops as long as u have some rpm low oil pressure soon as you slow down little to none. Light always is on. Never has a 40lbs. engine has less than 4000 miles on a complete rebuild maybe they didn't change that o-ring?. any ideas? Never has any noise in the engine no valve clatter.
ok i might have to try this.. i replaced the oil pressure switch a while back but the problem persisted so i read about the valve lifter oil filter so i cleaned it., it’s runs with without the shut off engine message now but still throwing a low pressure code once the engine warms up.. when i took the valve filter out it got a tiny hole poked in it from the tool that i used to remove it.. could this cause the low pressure code?
Thank you so much!
I have a 2005 Tahoe Z71 and I was driving and mine oil pressure dropped and the light came on the cluster, I pulled over and oil was leaking, what could this be?
Good video right to the point
I hope this fixes mine, because I've fixed oil pressure sensor and radiator that was cracked and I pray this is my issue I'll update tomorrow because we're gonna try it in the morning. 2001 Chevrolet Suburban 1500 V8 4wheel drive.
OZ, when I idle on a slope (back wheels elevated) I still have low oil pressure and a P0521 code even though the o-ring would be submerged in oil. (Already changed the sensor/wiring harness/oil filter) Do you think it’s the oil pump or still this o-ring? Thank you for any advice.
I wonder if anyone can help me. Ive been having thesame issues with my 310,454 mileage 2012 gmc Sierra sle 5.3L. I've changed the oil pressure sensor, new wires, new plugs, new alternator, new battery, new head gaskets. The timing tensioner was broken so i replaced the timing chain and tensioner. I also replaced the o ring on the pick up tube inside the oil pan. I also had a collapsed lifter that i had replaced. My voltage meter starts up and goes to 14 volts like it should. While I'm driving it goes down to 10 volts and pretty much remains there until i shut it off. Now after all the work that was done to it, i start it up and put it into drive and it stalls. I'm still having low oil pressure troubles as well. Can anyone tell me what i can do to fix this truck?
Hello John for the oil pressure issue you might wanna replace the oil galley plug inside the block. Its a plastic barbell with an O-ring that also goes bad. You can search here on youtube and see what im talking about.
So is there any possibility that this would have anything to do with the issue of gas diluting the oil? I have an 08 Suburban with the same engine. My oil pressure drops after 1200-1500 miles after an oil change. The oil is always full (not over full) but smells gassy. OnceI change the oil the problem goes away until 12-1500 miles later. I have a small oil leak coming from the top of the engine which I believe is the PC valve. I’ve been told that new injectors and replacement PC will “likely” fix the issue. Thoughts?
My 05 6.0 silverado has lifter noise when is cold but when is warm it goes away do u think this is the issue
I heard a bang under my middle seat on my front row. I have a crew cab six seater. So you can get an idea. The bang came right under the cup holder. Do you think it is still the o-ring or the actual pump. Right now the pan and all around the outside is full of oil. Like it leaked when it happened
I wonder if it's possible to add a 2nd o-ring as an insurance policy when doing this.
What is the name of the part that the o-ring was replaced on?
