@@MattsShop Will a 4L80 transmission bolt up to where a 4L60 trans was ? My 04 Avalanche 5.3 trans with 308K miles seems to be getting tired. Slow shifts into overdrive. I'm thinking about swapping to the 4L80 trans. You're right, it's easier to pull the engine on 4x4 truck, if you need to take the oil pan off. Dropping the front differential is a bi^ch. Btw, ALWAYS use Ac Delco parts, they work better than aftermarket parts. I've seen Bosch parts fail time after time.

@@ricktaylor3748dropping the diff is not terrible. You only need to lower it, not completely remove it.

[@ricktaylor3748]

@@poysunivey To me, it's easier to pull the engine, it's out where you can work on it with out laying on the ground. It makes it harder to work on when you're laying on your back, looking up, especially with jacks in my way. I want to replace the timing chain, cam and gears. I have to remove the water pump and timing cover. With the engine out, everything is in easy access. Also, the oil pan gasket is riveted to the block, you have to chisel or grind the rivets off to get the gasket off, it's much harder when you're upside down, and I don't have anyone to help me. Thanks for getting back with me.

[@poysunivey]

@@ricktaylor3748 first off, the oil pan gasket is not riveted to the block. It’s riveted to the oil pan. And if you’re doing all that extra work, pulling the engine makes sense. But if you’re just pulling the pan to change the gasket and o-ring, it’s excessive to pull the engine. It’s literally a 4hr job.

What is the torque on those oil pan bolts, ona vortex 5.3 🤔

[@knowledgeispower6192]

The oil pressure sensor has a small filter screen under the sensor on some models. I own three 1500s between 2000- 2005. Two of them needed the screens replaced along with the sensor because the screen was clogged. It dropped the pressure to the sensor.

[@JasPlun]

Having this done right now and intake manifold gasket. I went ahead and had them replace the oil pump as well I mean we are there truck has 176k miles and even though they never fail better to kill both birds at same time to avoid having to go there again. Intake manifold gasket as well has failed. Great video man!

[@EthanEdelen]

Why does my 01 Chevy Tahoe oil pressure sit 2 lines before 0 on cold start and sits at 0 when warmed up I installed a new oil pressure sensor and still reads the same. Any help would be appreciated thanks!

[@carloslona7721]

Hi mattsgop. I'm seeing the kit it's coming two o rings . The question is, if do I have to use both rings at the pipe.. so why it's coming 2 o rings.? Thank you..

[@MattsShop]

I've only ever used 1 oring some guys to put 2 orings on the tube. I don't recommend it.

[@RamosCma]

My oil pressure is low but my truck also ticks could it be related when when I accelerate the ticking stops for a little

[@MattsShop]

It is related. Don't want to run the engine with low oil pressure. Bad things happen.

[@StevenPaul001]

Have you come across any where they will get more oil pressure as they warm up

[@buzztrucker]

Your truck should increase in oil pressure as it warms up especially on a cold start.

[@MattsShop]

Yes! The oring expands once it warms up. So it seals better.

[@MattsShop]

Yea! Exactly.

[@StevenPaul001]

​I'm used to Old School small blocks that always had good oil pressure when they were cold. ​@@buzztruckeras far as I know I still have a stock pick up o-ring put on cold start its 40 psi but when I rev it a little bit it stays at 40 psi. Now on a typical small block Chevy they would start out 60 psi cold and maybe come down to 45-40 warm.

[@StevenPaul001]

Mine on cold start starts at 40 psi but it seems like if I just rev it a little bit it doesn't want to climb in oil pressure at all. Once warmed to operating temperature it will climb some to 60 psi. It's not very often but I have noticed a few times when I'm going to pass someone on the highway it will get to 80 psi

[@JuanRomo-k9c]

My truck is under 40 in idle but above or at 40 when i hit the gas , it has a upgraded cam doesnt make any tap or knocking nosies should i chance the o ring on pickup tube .?

[@MattsShop]

40 at idle is normal 50-60 on throttle is normal. They oring seams fine based off that.

[@JuanRomo-k9c]

@MattsShop it's at about 20 a lil over 20 in idle

[@JuanRomo-k9c]

Goes up to 40 when I'm giving it gas

[@saids.4489]

I just got an s-10 2003 4.3L when I cold start oil pressure reads 40 but after running for 10 min it starts to read 20 while running but when coming to a stop pressure drops to zero

You're welcome!

[@javierhuerta6795]

I got a chevy malibu 2013 oil pressure is low at idle when engine is warm get in p06de only that code, when engine is cold pressure is fine, but once is warm pressure start droping around 16-19 psi. You think i should try one of this methods?

[@buzztrucker]

I have an 00' Silverado 5.3 4x4 and on cold starts it says low oil pressure and then when it warms up it gets to the right oil pressure. I replaced the oil pressure sensor and it still does it and the readings are right. My guess is it's the oil pickup tube o-ring. What are your thoughts?

[@MattsShop]

Probably the oil pressure o-ring. They are contracted cold and heat up the expand then seal well.

[@poysunivey]

It’s the o-ring. Have you noticed that it only happens if you let it sit a day or two? If you start it everyday it will still build slowly, but you don’t get the warning? It’s basically the pickup losing prime due to the o-ring not sealing well. The oil pump has to reprime itself and it takes a couple seconds to pull oil back up to the pump and then you have pressure.

[@buzztrucker]

​@poysunivey yes that's exactly what's happening. When its on a cold morning start after a couple of days I get low oil pressure for just like 15 seconds then I get 40 to 60 psi reading. Then oil pressure is fine with no warning light on warm start or even a cold start with 24 hrs of driving. I'll replace the o-ring but I have 4x4 and not looking forward to it.

[@poysunivey]

@@buzztrucker it’s not terrible if you just lower the front axle about 8”. The more the better. If you have jack stands and ramps it helps. Put the jack stands under the frame of the truck to give you room to work, and use the jack to support and lower the axle.

[@warrenscott9990]

Question? My 04 6.0L oil pressure gauge isn't working. gauge Always reads maxed out pegged to the right. Is that the oil pressure sensor?

[@MattsShop]

Yes, the sensors do this I've seen that before.

[@warrenscott9990]

​​@@MattsShopwhat about that screen filter in under the sensor? How to get it out easy? I don't want to leave it in there. I got the old sensor out. Maybe there isn't a screen under mine but the parts picture at O'Reilly's showed one

[@warrenscott9990]

Update; for all accounts there wasn't a screen filter under the sensor on my 04 6.0L so I just put the new one in without it. Oil pressure gauge is working now

[@MyLifeThai371]

​@@warrenscott9990were you able to reach it with the special socket, or did you pull the intake manifold?

[@warrenscott9990]

@MyLifeThai371 I just reached back there with my hand. It was easy.

[@MrBowNaxe]

Would my 7.4 be the same?

[@MrCheck30]

Is it still the oring if my oil pressure is 40psi when cold, but when it warms up it goes down to 19 psi idle? Its so weird because it was 33 at idle two days ago lol.

[@MattsShop]

That sounds more like a bad sensor. They say it gets better when warm because the o-ring expands.

[@MrCheck30]

@@MattsShop I hope it is Matt, because its super cold out and I really don't wanna work on this escalade until June hahaha

[@shadoweruption]

Would this fix my oil pressure pinned to 80?

[@MattsShop]

No its the sensor more than likely.

[@burn31]

Replaced my o'ring but it still fluctuates from 20-40 psi when the engine warms up. When it's cold it stays at 40. Would a new sensor fix that?

[@MattsShop]

It's the sensor or gauge at this point. The oil pump can go bad, but they rarely do.

[@burn31]

@@MattsShop replaced the speedo with an Escalade version that has transmission temp gauge on it. Old and new speedo have the same fluctuation. Going to change the sensor and hope that helps. Thanks for answering.

[@kennyking2864]

After replacing my oil sensor I still don't have any pressure would you think it's the pick up tube like you said my truck had 289,905 on it please let me know

Yes

[@johndakota-v7w]

Is it the same on a vortec 4.3 v6 ?

[@MattsShop]

I'm not sure. 4.8, 5.3, and 6.0 for sure.

[@BobStoney__]

Would this also be the cause for high oil pressure

[@MattsShop]

No only if the sensor is bad.

[@Johnathan-l2o]

Could a product like AT 205 help with this problem. Since it's supposed to restore O rings and seals

[@MattsShop]

I don't use the oil swelling products. They can "help" but if you use the wrong ones or too much it can destroy every seal. I just replace the o-ring.

[@jeffclark5024]

Don’t forget the gauges in these trucks are known to go bad. Don’t always trust the gauge to be accurate before you go putting a pick up tube o-ring in. I’d also suggest just replacing the whole pickup tube if there’s any chance the previous owner did extend oil change intervals.

[@MattsShop]

Yeah, the gauges can go bad too. I feel like most people change the oring and then the sensor or the gauge if they still got problems.

[@jeffclark5024]

@@MattsShop It’s best to verify. Gauge fix or pressure sender is Waaaaay easier than a pickup tube o-ring. If you got suspected low pressure verify it with an actual gauge. Seen a TON of gauge failures on these trucks. If you have a capable scan tool you do a gauge sweep test. Then pull the filter and put the oil filter pressure check adapter on and go from there.

[@Koolblue900]

My 06 avalanche 4x4 sits at about 30psi idle and is at 40 on the highway do you think I need check out the o ring? I feel like that could also be what makes my lifter tap every so often. Already replaced the sensor when I first got the truck so I know that’s good

[@MattsShop]

If it was me: 2wd 30 PSI I'd check the o-ring. 4wd: 30 PSI I'd leave it alone for a while. They sit at about 40 PSI idle when oring is in good shape. Just depends if you want it 100% fixed.

[@raider5715]

My 5.3 oil pressure sits at ab 30 idle and just under 40 cruising ticks once it hits operating temp then goes away after 10 mins of driving until I turn it off and it’ll start to tick again till I drive it. Just recently dropped to 0 and gave me a warning light at idle while cold and I didn’t see it again is this still o ring issue?

[@eddievazquez2330]

I replaced oring pressure switch twice and now I get maxed out at 80 psi but running fine what can I do to fix mine 05 chevy silverado 1500 5.3 LM7

Is it stuck at 80 PSI? If it is, then it might be the dash cluster at this point. The gauge is stuck at 80 if you replaced everything.

[@darkh3lmet82]

The oil pressure has been low on my 2000 5.3 for a while now. Seems ok on start but once it heats up the pressure goes down to 20. After i actually drive a few miles it will go all the way to zero at stop lights and stays around 20 when driving. Taking it out of drive into neutral will bring it up enough to keep the oil light from coming on, but once i've driven a little further, the only thing i can do to keep the pressure up is give it a little gas at the lights. So I'm guessing o-ring? Hopefully not the pump... It's a 4x4 too so yay...

If they use AMSOIL that sludge wouldn’t be in the oil pan. AMSOIL is 100% synthetic and will not form burned oil deposits in your engine. AMSOIL has a strong detergent package to clean engines that have been using dinosaur petroleum products. Most oil brands that claim to be 100 % synthetic can actually be only 25 % synthetic oil and claim to be 100 %. Some people say AMSOIL is too expensive but it is good for up to 25,000 miles.
