Super Easy LS Oil Pump Install (Super High Mileage LQ4) 

Yeah people just need to follow Mellings instructions. If they say oil it, oil it. If they say rotate the engine 360 degrees, do it. Going beyond what a degreed engineer explicitly states is accomplishing nothing and is the truest form of ignorance. Melling literally makes oil pumps. They are the experts! Great video.

I like watching your videos. Your no nonsense use what you got available approach to building is fun to watch. Thanks

I am an ASE World Class Automotive Technician "Triple Master" and have 22+ Years Working Professionally. In all Brutal honesty I'm not going to say your incorrect and It's not that the internet made it over complicated. (The Smoke em procedure- when you tightened them down could of re-offset the pump gears lol) If you tighten the pump with shims installed you know it's perfect then you remove the shims. If you build an LS engine and you take extra care in making sure everything will come out flawless with your engine build you will shim the pump. This is by far one of the biggest issues with LS engines is Oil Pressure Problems in Pre-AFM/DoD and honestly even after... People aren't wrong when the pump housing has too much slack for the bolts and the gear CAN become uncentered and cause premature wear. You can not shim an oil pump and get 150k out of the engine. Or you can not shim the pump and get 20,000 miles. So why not make sure it's perfect. Not to mention I can't count with 100 hands how many times I've gotten inferior machined parts or defective parts and I want to make sure everything is set up flawlessly. It gives you the opportunity to look at the gears and making sure they mesh perfectly. Melling has a great reputation but everyone makes mistakes and all you can do is do everything in your power to take the time and not make them and throw the crappy parts at your service manager or if your at home family members.... lol... . Thanks for your video...

Couple flat washers stacked inside the bypass plug to make the spring a little tighter will easily give ya another 10-20 psi oil pressure and revive a oil pump that was losing pressure as well and yours looks good enough to do just that!

Great video, man! Quick and to the point, great advice :)

Great video informative THANKS

Every RU-vid video being an hour or more these days has been driving me crazy. It's refreshing to watch some shorter ones!

excellent video.. common sense trumps everything!!!! Cheers!

One thing you missed was the piston on the end of the relief spring galley. You want to make sure it’s not getting jammed up with a small piece of debris. That can cause loss of oil pressure if it gets hung up. Everything else was great! Short sweet and to the point! 😎👍

Yes you can reuse it. Just change change the pump gear and spring. Make sure it's super clean. The other thing is change that damn o ring on the pick up tube just under the pump

Keep up the good work, brother!!!

i like that stand

thanks for putting information out and helping others

He said he was installing the timing chain guide because he was lazy? I’m not gonna blast everything he did wrong I applaud him for wanting to help people ease the fears of installing an oil pump and getting wrong. I doubt not installing the guide might not cause issues right away but give it some time. I imagine once he gets some stretch things’ll be different

You make it look simple / great job thank you

Ya real easy other than how you forgot the whole part of putting on the oil pickup tube

Good video

Awesome video. Straight to the point and helpful.

Thank you so much.

Should you fill the oil pump with oil first or is it ok not to? Kinda like the oil filter

Thanks bro

The ball and float above that spring wear out and allows oil to bypass decreasing oil pressure. The rotary gears never wear out. So did you just pull this one to clean and re-seal?

Rear main seal video plz 4wd

Im in the middle of changing one out on a 99 4.8 with 70k miles on it. It was a government vehicle. When oil gauge showed dropping pressure and then none at all, i knew it probably wasn't a sensor. After draining the oil and pulling the filter, im not so sure now. Filter might as well have been filled with grease. Luckily im not seeing metal shavings. Good time to tear the heads off, it needs new gaskets as it was developing a leak on the exhaust side.😮

killer thriller

Might be a dumb question to ask but is there any difference between a 295 and a 296 Melling pump I have a 03 5.3P Chevy tryna see which one’s best any recommendations?

I'm feeling so old. I was curious as to longevity of the oil pump on my 2019 Silverado so of course I decided to RU-vid how to change it if I need. Here I thought it was as simple as taking off the oil pan like the old school oil pumps. The world is passing me by haha.

I think Mellings has a video showing this exact method

Man, that was cool !!! No Really.... Thanks

Well done Sir , thank you for the info . If I may I'll be using the smokem also ! It made me laugh .

Nothing wrong with that used pump, clean it up and put it back together for the next build. You can add a washer or shim in behind that spring for alil higher oil pressure.

Damn bro, you keeping loc tite in business with all that.

👍👍from this guy

When are U going to hookup the pickup tube?

looks easy !.. cept dont pinch the oring or ya got a headache a comin

So the 296 pump is for dod and afm engines while the 295 is for engines without it ?

Never did see the oil pick up tube installed !

good job 👍🏽!! only experts make it difficult, you make it easy , so does that make you better ! 😃--

Do you have to turn the crank after installing it? I forgot to do it

My 1st LS removal coming soon. #cdshawn

Waiting for the pick up piece to be installed too..

💪🏽💪🏽

How about easy knock sensor replace

So simple till its on the vehicle and you gotta drop the oil pan to get to the pickup tube 😂

Uh no pickup tube??

Clean 🧼 that oil pump and send it

“ I’m from green bow Alabama” - got the same accent. great video though.

It's not so easy when the motor is still in the truck or car.

dang you could have re-used that pump...

well apparently I didn't get the memo because when I put my new oil pump on a week ago I didn't do any of this I just put it on I've been driving the truck lol works just fine.

He tightened them in the wrong sequence

I don’t know how to tell you this but when you put the oil pump on, then backed it out and “smoked them” with the impact then tried torquing it to 18 😂. That don’t work like that. You literally went over with the gun. Also good practice when tightening things like that is go cross directional. If you tighten with gun you never getting 18. Even the m12 electronic wrench tightens to roughly 30. You over torqued those bolts like mf.

If you have any contact between the pump rotating parts and that pump housing, you're going to cause damage to the oil pump. That's why some people do the proper job and actually shim them in place. It's easier to do if you just take a one-and-a-half to two thousand shim and put it on the top, push put a 2000 Shem underneath and put it on lengthwise. You don't need to use three shims. Two long ones and put them in lengthwise one on top and one on the bottom. But doing this will cause damage about 30% of oil pumps that are put on that way. Do not listen to this man. Lucky don't cut it. Doing it right does. It's a hell of a lot easier to do it right than it is to do it over!

That pump is reusable. If it looks good then send it!!!

Scratched bearings

Yeah super easy when you have the engine out 😡

The oil pump needs to be centered no matter how much it flows or how much power you make. It literally only takes 5 minutes to do. Seems like such a careless mistake to make.

I wouldn't do that. I think it has to be shimmed. This is an emergency fix with no tools.
