Thanks, Yeah I figured there were some sort of disclaimer enabling GM to get away with not having to cover the repair.

 

I will let you know how it goes.

Anyone on here get this resolved?   I took mine in last week, 2014 5.3 with 73,XXX miles. Had a light come on and they said it was a couple other things and then ended up finding out it was in fact

Any tell tale signs of vacuum pump failure or is it just no signs and just sudden failure .

A friend of mine was a tech at a GM dealer for quite a few years until in the last 6 months or so he switched to Dodge because of a better offer and better management.  None the less when he was at GM he sent me a pic of an oil pump from a 2014 5.3.  The vein in the pump as well as the outer ring were both cracked..... said it was pretty common and they were doing one or two trucks a week for quite some time.  Not my cup of tea lol.

I'm a tech at a gm dealership. I personally have done 20+ oil pumps on 5.3 and 6.2 ecotec3 v8's. Starts out as a powersteering pump type noise, then gets louder until they catastrophically fail. Poor design, outer race in the pump that the veins ride on has a thin spot where it pivots on a pin. Race cracks and the veins hit the ridge. I've seen pumps fail as early as 7k miles. There is a tab for the issue. Sometimes it will set code p06DD for oil pressure control solenoid.

Yes! 2015 Silverado 5.3L, for about a week now, the truck had a whining noise like the old GM power steering pumps. I have been monitoring the transmission fluid temps, and oil pressure on a constant basis. About a mile from the house warning lights came on that said no oil pressure, and watched the oil pressure gauge go from high to 0. I shut her off immediately, the dealer out of Antioch sent a wrecker down to bring her back to the shop. Thank the lord we purchased extended coverage, currently 46k miles.  I’ll keep everyone posted next week.

 

UPDATE: our pump did fail, I asked the service person if they had any other complaints, she responded yes, there is a 2016 out there that has the same whining noise, and GM will not let them replace until it fails. I must say we did get excellent service, and the free use of. 19 z71 Silverado that we fell in love with.

My 2018 Silverado 5.3 just had a oil pump failure with 12000 miles. What tab are you referring to?

So I just had my oil pump repaired by way of a new motor. After they fixed it they called me and told me I have 2 bad injectors caused by this issue. The motor was covered under warranty but they are telling the injectors are coming out of pocket. Shouldn't the failure of the engine cover this issue? Also how does a truck that never threw a code have 2 bad injectors right after they replace the motor. Does this sound fishy to anyone else?

So they replaced the motor and used the old injectors? If yours was rebuilt I tell to check the codes. There wasn’t an injection problem until you messed with it.

Yep pretty much. Waiting on them to open this morning pretty much what I am going to say. Being as polite and respectful as possible.

Well to close my part of this thread, summary GMC Excutive Customer service told me I was not a priority customer and they would not be assisting or covering in the repair. (First time purchase of a truck and probably gonna look else where for my next one) Long story short pay to fix this or remove it from the shop. This is just after close to month of my truck in the shop. They did cover the motor and the labor for that but the injectors are not covered. Well good luck out there with them.

      Missing thrust bearing? And oil selection

      By Black02Silverado · Posted

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.

      Starting a new thread regarding mounting my 2014 OEM wheels to my 2026

      By revmanii · Posted

      So, lot's of googling and reading, and a trial fit found, that indeed they hit the newer fatter caliper. I did some re-testing today, and found just 3/16" worth of washers was enough for the wheel to spin freely. I added 2 more on each, and again it spun freely. Tested lock to lock with the 4 washers, about 5/16" not quite the 3/8" Im considering, but pretty close. No issues. I've been looking at the BORA .375" spacers and using extended lugnuts to get back lost thread due to the spacer. All the ET lugs I've seen are all .33" reach inside the wheel lug holes. For those that don't like spacers or think they're unsafe, I think it depends on what type of spacers you're using and making sure you get good quality hubcentric ones, and if you're using bolt on ones, regular mainenance, checking the spacer lugs. Not wanting or needing that much spread. Looking for the minimum that will let me run these rims and tires.  it does look to stick out a little, but I really want put these on. and use the stock all-terrains in the winter.
