Oil Inlet Tube O-Ring Replacement Without Removing Differential (5.3l / 6.0l / 6.2l)

[@wyatthurst3820]

I know this is an old video but if you're seeing this, thank you man. I used this vid as a guide to replace my pickup tube o ring. Truck hit 0 PSI the other day during single digit Temps and none of the shops in my area would take it for weeks. My stepfather and I did it in my driveway with about 10 hours of labor since it was so cold. If anybody is debating on this, do it now. I am no mechanic and I did it laying on my back in the snow.

[@FarmDad]

Great job man! I did a head gasket on my buddy's old jeep Cherokee once during a snow storm. About froze to death, lol, but it's a great memory now.

[@swensonswenson4416]

What were your signs it was bad? I have an 08 1500 and I put a new oil pressure sensor and screen in but that didn’t do anything. I have pressure right away when I start the truck not a lot but around 25 psi but once it warms up I have nothing

[@FarmDad]

@@swensonswenson4416 check out this video kzbin.info/www/bejne/q3vVpIBmm9qNjMk. If I was you, I would try a motor flush first. If that doesn't work, it's likely the o-ring.

[@wyatthurst3820]

@swensonswenson4416 I was experiencing about 25 PSI at startup at 10 ish psi once warmed up. Then one day all of a sudden I got 0. I've done regular motor flushes in the past so I figured it was either the O ring or the oil pump, and since the pan had to come off either way I got into thr job. Upon examination of the o ring which was flat and a brittle, I was confident the oil pump wasn't at fault. New o ring and voila, 60 psi at start up and 40-42 once warmed up

Exactly. One of the benefits of doing it yourself is you can easily add on some other maintenance items 👍👍

[@FarmDad]

Words of wisdom. Agree 100%.

[@jsflagstad]

Just replaced the O-ring on my son's 08 Silverado 5.3. The old o-ring "looked" fine but was pretty stiff and the new o-ring fixed the problem 100%. I dropped the entire diff assembly out of the vehicle and it made it easier. I also took the bolts out of the rack and pinion and dropped it down a bit as well. Without dropping the rack and pinion down, I don't think I could have gotten the pan out. Hopefully this helps someone that may run into the same issue. It really wasn't that bad to drop the diff out and drop the rack down, if I had to do another one, I'd do it the same way.

[@FarmDad]

Glad you got it all fixed up. For me, by leaving one side of diff still attached, I save a ton of time getting it all back in and together, because it just swings back up and right into place. Perhaps I like this because I'm working alone. But whatever works best for you is awesome.

[@jsflagstad]

@@FarmDad Thanks again for the video as it was a big help in planning what I would be up against. I do have a hoist so I was able to lower the diff easily with a trans jack. And I was replacing the driver-side wheel bearing and axle shaft while doing this repair so it was just off with the driveshaft and the pass side 6 axle flange bolts, the wiring harness, and the vacuum hose, and the diff was out of the way. I also dropped it into the parts washer and had my son clean it up good from the miles and years of oil and debris that had collected on it. Thanks again! :)

[@gjones5153]

I replaced my pan gasket and broken o ring I only lowered my differential but afterwards I wish I had removed it completely because it was very hard to get the pan and gasket back on the engine.

[@ThatGuy_Hunter]

It’s much easier to just drop the diff out. You are 1 cv axle away anyways. Then you have all the space you could ever need, no wiggling, no tight squeeze. I’ve done them both ways, and the extra few mins to take it out completely saves time in the long run. Rivet the gasket back on for ease of reinstall

[@FarmDad]

I've done it both ways as well and found this easier when you are working alone. It's not that tight in my opinion and it eliminates the struggle of getting the diff lined back up to be reinstalled. To each his own. Thanks for watching and commenting.

[@BattlefrontMemphis]

Run an engine oil flush product before you do this. You basically add the flush to the engine oil, let it run and cycle the flush for 5-10 mins at idle, then change the oil and filter. Doing that totally fixed low oil pressure on the dash. The sludge in the oil had clogged up the oil screen and oil sensor. The flush cleaned both and my oil pressure jumped back up to normal.

[@FarmDad]

Lol, I am literally the person who first made a video and spread the word about engine flushes and sludge causing these issues. I spread the word to every tech I knew and made a video that's elsewhere on my channel. I love that my fix has now come full circle 🤣🤟👍.

[@mstehelin]

I used your video to as a guide. Worked like a charm! Went from Zero to over half way on the gauge. Couple of thoughts. 1st is my oil sensor plug was different than the video. I ended up clipping the wires and repairing them. Turns out trick to removing my sensor plug is to get a right angle pick under the tab (Thats hidden in the 'nut' of the oil sensor). I did not pull the drive shaft or the right hand CV. IT was super tight, But I was able to do it. (It sucked IS there any other way of getting the diff lower?). I would recommend riveting the gasket on the pan. Finally the Torque spec I used for the Differential Nuts and bolts was 75 foot lbs. For the cross member 68 Foot Lbs. For the Pan bolts 18foot lbs. and the 2 skinny bolts at the end were 106 INCH lbs. (Took me two days btw)

[@FarmDad]

Awesome job, buddy! Glad the video helped get you going.

[@ronsimon9346]

I just completed this same job on my yukon..I ended up having to drop differential completely..sounds like a bigger deal than I actually was. Wasted allot of time trying to finagle the oil pan out, may be easier for less experienced mechanics to just drop differential

[@scottnewell4314]

I just did this yesterday. Went from oil pressure dropping after warm up to 0 pressure. New o ring, gaskets, oil, filter etc. Pressure sensor was changed last year. What did I do wrong?

[@FarmDad]

Sounds like you are probably going to need to drop that pan again and see what you see. 😔

[@wisconsinwoodsman1987]

Trying to figure out if the 4.3L Vortec V6 used on Sonoma and S-10 has that same O-ring. I can't find a part number for the O-ring for my truck, thus wondering if one exists.

[@wisconsinwoodsman1987]

Turns out the 4.3 does not have that O-ring.

[@chrislmcnair]

My oil pressure has always set at 80 and now it still sits at 80 unless I get on it and then it goes to 0, when I let off the gas, it goes back to 80. Maybe its a sensor issue? It's been at 80 for 8-10 years since I bought it with 68k. Thanks for the video, I got stuck on the diff yesterday but, I will try and tackle the rest in a couple days, with the new knowledge.

Is there a way to do this where i dont have to change the oil again? I literally just got an oil change... I'd hate to dump all the new oil. Guess i can just wait until I do my next oil change.

You could catch and reuse your oil, but it's normally easier and better just to change it.

[@alexwharton7407]

Amazing video! Where was your pressure before and after the swap? I have a 2009 5.3, I get 20 at idle and I'm lucky if I hit 40 when driving. Engine is quiet when it's cold, but it starts ticking as it heats up and pressure drops. Does this sound like it could be the O ring?

[@FarmDad]

Mine was dropping below 10 and setting off the warning. These ls engines actually run fairly low pressure, so yours doesn't sound too bad to me. But the age of yours makes me think it's still not a bad idea to do the o-rings. This video should also help you: kzbin.info/www/bejne/q3vVpIBmm9qNjMk. thanks!

@@FarmDad Thanks! Yeah, it has 245k. Think I may give this a shot. Watched the other video, think I will try that first. I tried cleaning with ATF, which partially clogged my filter bringing my pressure down to 15, then the engine was VERY noisy, so there has to be gunk in there.

[@jovanhyangeles5056]

@@alexwharton7407 I am having the same issue, did you ever find out what’s causing it?

[@alexwharton7407]

@@jovanhyangeles5056 mine ended up being carbon buildup in the cylinders. Remove the spark plugs and sprayed some cleaner inside, then I switched to E85 and it has been slowly clearing that all out. Maybe 70% quieter? I think it only happened to my vehicle because the previous owner only drove about four blocks to work, so the vehicle took a lot of very short trips for the last year or so before I bought it. So my noise didn't actually have anything to do with oil pressure, it just got louder as the engine heated up and the metal expanded slightly, causing the carbon on the cylinders come in contact with the carbon buildup on the Pistons. I thought it got louder when my filter was clogged, but I think it was just because it's much louder when it is in tow haul mode because of the higher RPMs.

I believe we have replaced the oil sending unit on the Tahoe but still getting oil pressure warnings. I believe we're at 18psi for oil pressure when at 2k RPM but idling drops it to 0 and hoping to get it fixed very soon.

Bought a used 2005 silverado with 5.3. Ran perfect the first week put 350 easy miles on it no issues quiet as can be. Changed the oil and the next week I drove it I ran into issues that got worse and worse. First thing was sometimes on startup it would blow a huge cloud of smoke and then it wouldn't do it anymore. Another is a loud tick would start to occur on idle and I'd notice the oil pressure fluctuates between 25-45. If I ran it to 40 psi while driving it goes away. Think this is my issue?

[@FarmDad]

This issue would probably cause lower oil pressure than what you are seeing.

@@FarmDad I have since learned that this method won't work for 2002-2009 Envoys, Trailblazers, Bravadas, Rainers, Ascenders, and some other models, because those have the differential that goes through (yes, through) the oil pan. So the only way to get the oil pan off is to remove (or at least disconnect the front diff), remove the intermediate shaft, and remove the front diff actuator. The procedure is detailed in this linked video: kzbin.info/www/bejne/o2KTkqqefK-bnKs . That's not to take away from this great and very helpful video - it just applies to newer V8s.

[@lubacotemobile]

Kind of lost me right before the diff drop. So you left the driver side axle connected and just lowered the front diff? Maybe I will watch again.

[@FarmDad]

That's pretty much it. Leave one side connected and swing other down. You'll have enough room to do what you need in there and be able to put it all back together easier because it'll just swing back up into place.

[@dsolo3250]

[@FarmDad]

No that's not what I did. If you remove the whole differential, you have to realign it and fight to get it back in place. Not bad if you have help but a real pain by yourself. My method only removes one side of the diff so that all you have to do is swing it back up into place. You don't have to realign anything and it's a much easier one man job. It sounds like you were expecting some sort of miracle, but this is as easy as the job gets. As any good dad would say, stop complaining and get to work.

Not when you are working by yourself. Those diffs aren't easy to get back up in there and lined up by yourself. This way, you swing it down, do the job, then just swing it back up into place. Everything lines back up, no fighting it, and one man can do it no problem.
