- Dusty explains how the oil pickup O-ring is so important to you oil pressure and why having the wrong one(or it being installed incorrectly) can really affect oil pressure and longevity of your engine!
Genius about the check for oil o ring by jacking rear of truck up never thought of that
Works great for sure
Adding the specs in there was top notch. Thank you.
Thank you!
Great info. Doing a build now and installing a new pump. Definitely will be going in to the install more confidently with this info. Thanks.
Glad it helped
For some reason the O ring that I bought from Holden in Australia for my 5.7 litre Chevrolet LS1 V8 engine was Blue & the original one was green.
Apparently the thicker red O ring is used in the truck engines.
Whatever O ring it is they get cut easily upon installation & even at the factory !
UA-cam GOLD right here thanks for sharing!
You're welcome
Thanks great information, quick and to the point, appreciate you not putting in filler to make a long boring video.
Glad it was helpful!
Stright to the point !! Thanks for the info!!
Glad it was helpful!
Thank u so much for the video
You're welcome
Also your lifters will sound like they fail if you pinch the oring. Shop did that to me this week
I just did mine. It had the groove and I used the melting green ring. I lubricated it with oil first but it pushed in hard… once pushed in it seemed like there was a reasonable amount of movement though. Same exact behavior after replacement, 30psi hot idle, it always had at least 40 before about 20k miles ago. Coming up on 300k and I was hoping this would fix it. So these aren’t supposed to push them fairly hard?
Good honest information. Great video guys
Thank you!
Glad that was the problem 😇
It's much better than it was!
Having that issue now lol smh, getting it fixed today
Sorry to hear!
I have a 2017 w low oil pressure and I was going to replace the pickup o-ring but the parts store said they don’t know w I’m talking about
Try their commercial counter if they have one.
Yes they sell parts barely
That wouldn’t surprise me if they don’t have squeezed number there lost . I would use the green print it’s a little thicker might have to go online at Melling.
Did you recently do any kind of mods to motor that might have caused low oil pressure , have you tried another pressure sensor ? Ususally it’s in the mains and not a easy fix unless you send it out to have crank work done. Might try to put in new pump from Melling a high volume pump
Did you have to drop oil pan a little and raise the engine for pickup tube bolt?
Drop the pan slightly
great info! thanks!
Thank you!
Great info!!!!
Thanks
Pro tip!
We try to help when we can!
So I can just take the front of the engine off instead of dropping the front end and oil pan
You have to at least lower the front of the oil pan
Thanks for the tips. Could it still be o ring if psi drops as it warms up? Also, how long can i run it with 3 extra quarts as i need to get the temps up.
I'm having the same issue after my rebuild. I've changed the thermostat already because it was running a stock temperature thermostat and thinking it needs a heavier weight oil. Maybe 10w40
@ChitownMilcrib I ended up going with 10w40 about a month ago and now the pressure stabilizes just about right after warm up. I think I still want to upgrade my pump to at least match the rest of my build. It's a bit loose so switching the oil helped tremendously!
@@FlippedNormal that's what I'm about to do now . Have you tried break in oil or zinc additives for a little extra protection?
My 2013 Silverado does the same thing. It runs ok until the engine gets to operating temperature and gradually loses pressure until it's a tad bit over 0psi.
@@eriktorres8975same on my 03 , did you figure it out bro?
My cold startup pressure is ok but hot went to 10pm I
Can This still be a oring ? Does the 3 quart extra trick always work ?
Extra oil will always work to check to see if it is the o ring as it covers the oil ring opening with oil. You may have other issues, but this will rule the o ring out.
Okay I have a question planning on doing the AFM/DOD delete. With cam lifers and new gaskets on my LC9. And I was bitten by the while I’m in there big. So I’m gonna do new oil pump etc. etc. is it possible to get a oil pump with to much volume for a lc9. I just want to put a good oil pump in my truck after doing the AFM/DOD delete.
What about the gen 4 ls motors 2007-2014 5.3/6.2 they take the orange ones right? All the mellings that come up is orange?
What happens if you were to mistakenly put the thicker green O-ring on the 99-02 model ? Same results as far as low oil pressure???
Most likely as it would be loose on the pickup tube
What’s that tool called that measure the circumference..? I find it fascinating I want one
Digital Vernier Caliper
Very good information 👌 👍.just subbed aswell
Thank yoy
Same problem here. 10psi hot idle. About 25 cruising at 1800 rpm.
How did you get the oil pump out without dropping the pan?
You can drop the front of the pan some...
My pickup tube is around .87’ on both bottom and top (straight) , should I use the black o-ring ? Or should I put a oem orange (a bit thicker than black, but thinner than green o-ring)
Oil pump : melting 10295
Not for sure but you 3 thousands off as well I’d say probably the green in the video
But as he stated don’t force it Vaseline on both mating surfaces should at the most feel a slight pop when the tube and oring seats shouldn’t have to force it with the bolt or anything yet on the other hand makes sure it’s snug when it seats
What’s the proper pressure at WOT 5-6k rpm?
At least 40s id feel ok with
I have a 2003 gmc yukon 6.0 v8 about a week ago I noticed my oil pressure was dropping used to be a tad under 40 while at about 1800 rpm going 60-65 mph now its at the quarter mark so 20 psi. I've seen that it could be that o ring what do you think?
Could be. Jack the back up and sew what it does. Freah oil and a quality filter could also help
Is it possible to loose pump prim after it sets overnight , it seems to be doing that for whatever reason not reall sure but when I start first thing in the morning it sounds dry then has soon has oil pressure gets up it quits . And it won’t do it again until it sets for awhile several hours or more. Just wondering if it was possible and would it be pump , oring, or filter. Thanks
Na...
Also remembered a major problem with oil divert or in pan , had a idea and it wasn’t a good one at all. Took out divertor thought it would help but the opposite was true. It caused a lot of problems with using a lot of oil , leaks at rear cover and decreased pressure has soon has I fixed it everything return back to normal. Don’t remove it and leave out bad idea !
Low oil pressure to me was at 40 and it should of been slot more since I had just went thru motor, oil divertor I guess being left open caused a lot of problems but I did notice pressure went up to bout 65-70 much better.
What about a ls6 I looked down at my oil and it was almost 300 degrees and ppl told me it was the oil pump do you think that’s what it is?
Check your ground for that sensor
My 2011 ls3 is showing low oil pressure we put it on the scanner and it was reading 16psi then started going down and got down to 4psi
Not good. Maybe it is just the sender?!
@@nufnuffz28 replaced the sensor, I have lost oil pressure. It’s now being rebuilt.
@@bryceaustin953 sorry to hear that
Mine at around 15 psi warm but cold it’s fine after like 20 min drops to 15 in traffic
Did this fix your problem
On this car, yes
What was the oil pressure when it was low
This one was 12 or so hot idle
So how do you get the oil pressure back
Pull the motor replace the cam bearings with good ones one piece not rolled like GM used there JUNK!!!
That’s not why ls motors have low oil pressure. They have low oil pressure because the oem unit is junk.
I have a Cts V 2011 what color gasket seal should I use ?
Aftermarket is most likely red. Stock will be black. Its the bigger one.
@@nufnuffz28 thank you
What should be a good oil pressure around how much psi?
A lot of variables. But hot idle I like to see at least 27 up
@@nufnuffz28 my g8 gt has an oil pressure gauge and at idle it’ll go down to one bar and starting overheating I’ll have to rev it up to keep the oil pressure going and I just don’t know what the issue is. Has a fresh oil change and no check engine light just the oil light..
@@crazyfrank3866 The overheating and 1 bar oil pressure thing are most likely not related. The overheating is the fans, radiator, or low coolant most likely!
@@nufnuffz28 gotcha I just gotten a new water pump and a fresh fluid change so and both fans work so I’ve just been stumped on what the issue is
@@crazyfrank3866 did you ever figure it out?. Mine was the stupid radiator cap. Oring was bad and worn out. Try that
Worn out engine
Common problem as well!
Number 2 cam bearing is the culprit and it's only going to get worse!!!🤔 dont waste your time and money replace the cam bearings factory GM bearings SUCK!!!
They suck so bad they run fine for 300k+ miles on those bearings
Very poor explanation !!
Thank you!
