me exactly right now. but went in for a cracked flexplate

Just did it today,Oil pan gasket was leaking and replaced it while I was at it

interesting

Yes lots of EFI bikes and cars have this feature as a flood mode and don’t splay fuel. It’s also better to have the throttle open to spin

Thank you I have 2005 Yukon and I changed my oil pressure sensor first but it didn’t work but I will try this now .. had a guy tell the truck was no good anymore

At that point I'd suggest the oil pressure sending unit. They're known to have issues with time as well.

@@tt7hvn I replaced that about 6 months ago. Oem part. I think my pump has 160k miles worth of wear and the pressure is what it is. I'm happy the tick is gone. Has stayed gone for 2500 miles so far.

@@doubleya215 also, given that's it's an 04, those gauges are known to have issues in the stepper motors....

Yeah its a very common problem. Fix it before it eats your cam bearings.

I'm doing mine this weekend as well. Garage wants 1300 to do it? Saying the timing cover needs to come off! 🤦‍♂️Smh

@@mikew7561 They must be looking to replace it from the top. Its actually a pretty simple job, time consuming if you have a 4wd. Since you have to drop the front axel.

@@mrogersgmt800 I get that You can replace JUST the O ring from the top!. But I was having them quote the Pick up tube as well.

@@mrogersgmt800 Needles to say I was only Going that route because I don't have the time? Normally I do all my own repairs. So looks like I'm tackling it This Saturday anyway lol

@@mikew7561 Same here if I remember correctly I was quoted $700 for the job, needless to say tackled it myself. Fun stuff!

Thank you! 😃

How was it?

That's how I do it...I just don't film it.... only my "driveway" is grass, well....a mud puddle. One jack, 2 jack stands on top of 12x12 concrete walkway pavers. I use the jack as a saftey to the jack stands and lay a piece of plywood down underneath to lay on and harbor freight puzzle mat pieces to extend that to awkward spots. I just finished mine at 1130 last night and the thing is sitting out there on the board and stands with no oil in it waiting on the rtv to cure while its pouring out cats and dogs. Least you have an actual driveway. It could be worse,.... you could be me. Fingers crossed this SOB don't leak on me later when I fill er up with oil and run it🤞🤞! Cuz some dumb ass took an impact gun to my oil cooler bolts and transmission to pan bolts and stripped one of each so I can't torque one of the transmission bolts to spec and the one oil cooler bolt feels like if I give it even another half of a quarter turn (1/8😂) its gonna let go.... so I'm leaving it alone and praying 🙏..... if it don't hold I'm into doing the whole job in the mud again and having to buy another entire oil pan because some idiot decided it was a good idea to ugga dugga steel fasteners into aluminum! So that'll be another full day and another $150+ depending on if I can reuse the oil pan gasket after getting it in contact with RTV. 🙄😮‍💨😤

Your welcome. Glad it has helped.

Thank you. Glad I could help.

I did follow the sequence and always do when doing these type of things.

Thank you

Thank you

Also from ky but in Louisville. Thanks for the video i need to do my denali thanks for the video this will help

Is the torque specs for pick up tube around 18ft lbs

I dont believe so. You could have a blocked passage in the oil pan there by the filter since oil passes thru it.

Thank you. The oil pressure needs to be verified using a mechanical gauge or scan tool. If you do have a oil problem it could be from debris left in the oil pan possible clogging the pickup tube. Thats just a guess seeing you just had those things replaced.

@@4LaneBlacktop Troubleshooting is starting simple and looking where people have been working

@@allanbrogdon5317 Very good advice, Allan.

Appreciate it

Probably is the cam bearings.

Thank you. Glad it was helpful.

@@4LaneBlacktop combien de pression d'huile avez-vous avant de changer le joint toriques ?

Low oil pressure will cause ticking. The top end will be the first part to suffer as it is the furthest point away from the oil pump. On these ls engines, the cam bearings start to go first under low oil pressure.

4Lane Blacktop I’m sorry if I’m asking a lot I just don’t have much experience, my truck is 5.3 and has this ticking problem, how can I make sure that the problem is the pickup tube O-ring ? Are there any more symptoms? because when I took the car to the mechanic he told me it’s the camshaft and I should swap the engine or replace the camshaft, someone told me replacing the oil pickup tube o ring has fixed his car so I don’t know what to do now, I think the mechanic was trying to deceive me and take a lot of money😭. Please help me

Yes, do a oil flush, get K&W/CRC 5 minute engine flush or LiqiMoly engine flush, flush engine, drain, replace pickup tube o ring and pan gasket. It fixes 4.8-6.0, Id say it does so on LS1 as well.

Yep, the lifters in my 5.3 were ticking badly for probably 20,000 miles, I finally decided to do the o-ring and they are quite once again

@@saifalkaabi9121 did you ever change the o ring and did it help it

Not sure but it probably was the first time when I done it.

How did yours go.? I have an 06 as well & it seems there's more that'll need to be removed than earlier models.

The engine was not really making noise, the oil pressure gauge was reading low. The repair was initially for a leaking pan gasket. As far a using a thicker oil with a engine with a bunch of mileage that should be fine. 20w 50 might be a bit much but 10w 30 should be ok.

Should be. There might be a few more or less steps getting to the oil pan but otherwise its the same.

There is no steering rack on this model. It has a box on the frame rail.

If you have rack and pinion, yes loosen both sides and pull the bolt on the passenger side so the pan has enough room to pass the pickup tube.

Yes I did use ramps. It stayed on the ramps the whole time. Plenty of room to get the diff down enough to remove the pan.

@@4LaneBlacktop Thank you. Until i can sneak a lift in my garage without my wife noticeing, would much rather use ramps than jacks!

Just pulled a transmission and oil pan with the same ramps. Plenty of room for everything

Im going to say probably not

It should be the same

Thanks

There are different color orings depending on what pickup tube you have. You can google it. Also oring replacement is not a guarantee fix if you have other issues. Mileage, bearing wear, and oil pump condition all play factors too. Verify pressure with a scan tool if you can. In theory you want atleast 10psi for every 1000 rpms at operating temp.

It should be exactly the same.

Im not exactly familiar with the bypass issue you are having but I would think that the bypass is in the oil pump. You should probably hook up a manual oil pressure gauge and verify the actual oil pressure. Many things can cause low oil pressure and this o ring is just one of them. Excessive bearing clearance is also one too and with these gm ls based engines the cam bearings can be the cause also. Many things there to check.

Yes the bearings, definitely a possibility. But this bypass pressure valve I have found out that is inside the oil pan, goes bad, very similar to the blowoff in the oil pump, I didn’t even know about this. But Melling makes the part and a new designed part in addition that saves on oil consumption. On the oil pan it is located over by those two holes for the oil cooler. I replaced the oil pump, the O-ring on pickup tube, the oil pressure sensor and screen. If the truck is started from cold start, there is oil pressure of 40lbs. After 10 mins it goes to zero and alarm sounding. Shut it off and wait, start again oil pressure goes up. And repeat. So I am at a loss. I don’t want to take all this apart to look inside the oil pan but it seems like there is no other option. Idk what else could cause this. So give this oil pan internal relief valve a look and if you ever take a pan down replace that part. It feeds the VLOM on top. Cheers Kevin

Do you think a leak in oil cooler lines could cause oil pressure to drop to that dangerous level? Thanks Kevin

@Kevin Fraser it would have to a a pretty good sized leak. Also, I have a buddy that owned a machine shop. He said that he only used oem gm oil pumps on the ls series engine because he had problems with aftermarket ones. I believe there is actually a shimming process for the oil pump also.

Wow, I think I used a Melling oil pump. Was a straight forward bolting application. I also changed the pick up tube O-ring from that point too. And added the second bolt even on the pickup tube flange. It’s about two years old, hard to believe the new pump went bad or the O ring again. I have oil around both sides of the oil pan. Even though bolts don’t feel loose at all. The oil cooler I think is leaking. I don’t see oil from a rear main seal. I’m drawing at straws. The corners of the oil pan leak traditionally, maybe the pick up tube is even picking up debris and blocking the tube after ten mins of warming up. Hard to explain the drop . If you look at your video of pop Pam down you will see that like 1/2 inch valve in corner. Ugh, thank you so much for answering 🍀

At idle and with the engine at operating condition that should be normal.

There are different colors but from what I understand there are 2 sizes. Just make sure you use the right sized one.

I don't believe there is a top bolt on the driver side. I just removed the 3 bolts as I pointed out in the video

It should be easier to get underneath

Should be about the same. From what I understand is most LS series engine have this problem with age and mileage.

4Lane Blacktop thanks for the quick reply👍🏻

Yes it’s exactly the same. I have the 6.2 and am in the middle of the super low oil pressure that collapsed the lifters. Did the lifters and after a week the oil pressure dropped to bell and siren ringing shut the engine down. I got the O-ring and oil pump off. My O ring 193,000 miles was flattened on sides. And a slight crack in it. Not a smoking gun yet. Maybe it’s the blow off valve sticking in the oil pump. Another typical issue. But when Autozone finally sends it to me I’ll replace and let you know if it fixes the problem. I still wonder why, does GM use just an O ring that fails, instead of using both bolt holes on the pick up tube with a two hole flange and flat gasket that seems to be a better way to ensure there’s not such a failure.

@@kevinfraser640 what happened

@@chifhaaji4518hey ladd, so this job worked. But down the road I feel that this Other Not well know Relief valve INSIDE the Oil Pan, is causing a drop in oil pressure. I did lifters. While doing so I changed sensor and screen filter under it, changed oil pump, that has a relief valve too. So all this is new. I also changed the O ring from front and added an additional bolt in the flange so it has two bolts now in O ring flange. So there is no other reason , maybe besides worn cam, that could cause Low oil pressure to actually sound alarm, than this relief valve in the pan. Does anyone have thoughts on this Relief/bypass valve in the pan? I have to attempt this now and might just close it off with a bolt. I’ll let you know how it goes. Cheers Kevin

Not necessarily but not lubing it up can cause the oring to get damaged when reinstalling the pickup tube.

@@4LaneBlacktop Thanks for your reply. This is my first build and I think Im trippin because have had so many delays and Im still assembling. I put my pickup tube in while the engine was upside down on the stand. Im going to hope I didn't pinch it but at least I found a video that shows me how to lower the front differential without completely removing it so I can get to my pan. I'll just keep my eye on that pressure for a while once I get it going again.

Expect it to take around 2 or 3 hours.

Yes there are torque specs. I do not know them off the top of my head.

I found them thx

I would say under 20 at cold idle

You can do it in a couple hours.

Hard to say without doing test.

Yes. Lots of highway miles

@@4LaneBlacktop Great to know your high mileage engine still running strong. Just bought my 05 Denali with 303k and gotta do the O ring. Great inspiring video to tackle it myself. Thanks ✊💯

No but the oil pressure gauge was reading low.

You probably have a restriction somewhere or oil viscosity is too high. Oil thins as it heats up and parts expand which is why oil pressure drops after warm up.

@@4LaneBlacktop oil pressure is low when starts have to give it gas to rev engine up to make pressure go up as It get warm oil pressure stays at a good pressure

@@garygriffith2398 you ever figure out the issue? I’m experiencing the same and plan to go ahead and refresh the oil pump, oil pickup o ring, and oil sending unit.

Yes it is. Bought it vandalized You can see the whole series here kzfaq.info/sun/PL-arRGUA-sv_-KCtJ88wsYiYc3JHrVHjF

Take the mounting bolts out so you can move the diff down a little thats it.

Taking the mounting bolts out is damn near impossible.
