So I drove my 2014 Crew Cab (5.3) down to Florida from NY. About 300 miles before my destination the check engine light came on, and the oil pressure shot up to 60Ibs at idle..I got it scanned and it came back with a oil pressure sensor code. I cleared the code and continued driving to my destination, while the pressure was steady at 40-60lbs @2k rpm. When I got in I left the truck at a Chevy dealer and they are telling me that my oil pump is shot, and it will cost me $2500 to get it replaced. Apparently the pump is a two stage pump and there's a spring that regulates if the pump is at low pressure or high pressure, and the tech believes that it broke and it's stuck at high pressure. My thing is that I've been driving the truck for a few days before dropping it at the dealer and the truck was fine, while the oil pressure kinda alternates, and I'm trying to decide if I can drive the truck back home and have my mechanic fix it instead. My guy said to me that as long as there is oil pressure and I don't push the truck, that it should be fine. I really don't want to have to fix it in the middle of my vacation either so I'm asking for your opinion. attached a few pics. Thanks in advance for any help provided.8b5a5c5512a8f73f1c2745ff1ef0e058.jpge4f26c76f47f7ec27834344bea37a31c.jpgf65aae4f0797ece44be8d0d7a4b52875.jpg

I suggest checking your oil level.  Could be too high or too low.

Sorry to hear this, what oil and filter are you using??

I’d take it to a quick oil line place if your choice and have your choice of oil manufacturer done on it. May be just the filter but just get it done and see if this does it.

spin on a new AC Delco oil filter top off oil to correct amount.  If the Pressure still reads the same you can drive it back home.  Just be ready to turn off immediately if pressure drops!!! easier said than done depending on sitting in parking lot idling or traveling up/down grade in thick traffic!

The chevy dealer did a new oil and filter change and the symptoms got worse.

Yep needs oil pump. There’s a bulletin for the spring breaking. It defaults to max commanded when it’s broken so as long as you see some pressure you’ll be alright, however I wouldn’t risk it. If you’re on the interstate and it completely let’s go and you need a tow then you’ll be in a world of hurt.

Interesting. That's the first I've heard of this on our trucks. Is this an early model thing? Have they ever updated the pump and used a revised one? Because I notice the OP's is a 2014, first year of the new direct injected ecotec family.

Well, I bit the bullet and dropped the truck off at a GMC dealer this afternoon. I asked them to save the pump so I can take a look at it. I'll post updates

I could be wrong, but $2500 seems high to me for an oil pump R&R, especially if the truck is 4wd. The pump itself is a $200 part. They should be able to get at it from underneath and in front & shouldn't take more than a day to do; unless I'm missing something?

I believe it calls for over 10 hour labor. So roughly $1200-1500 in labor alone. Plus misc parts required for replacement. I was thankfully able to get them to warranty mine when I had it in for lifter/cam replacement.

Wont hurt to drive. It's a 2 stage oil pump. High pressure for AFM, low pressure at normal operation. You need a new one though. Many people that do the AFM delete also swap out the 2-stage oil pump.

      AFM Disabler Question

      By BlueV8 · Posted

      A complete delete is the most thorough mechanical solution, but it is also major engine work. On a quiet truck that is still under extended warranty, opening the engine purely as prevention is difficult to justify. A plug-in disabler stops commanded cylinder deactivation, but it does not remove or repair the collapsible lifters, so it should not be treated as failure insurance. I would keep the oil full, document the maintenance, and have any persistent tick, misfire, or loss of power diagnosed promptly. If the engine eventually has to come apart, that is the logical time to compare an OEM-style repair with a complete delete. The right choice depends on the truck’s symptoms, warranty status, expected ownership period, and whether the engine already needs to be opened. We explain that decision in more detail here—full disclosure, this is our own guide: https://www.bluev8.com/blogs/news/do-you-actually-need-an-afm-disabler   One exception: some 2021 L82/L84 trucks have RPO YK9, meaning cylinder deactivation was already disabled in the factory ECM; on those trucks a plug-in disabler is redundant, although the AFM/DFM hardware remains inside the engine.

      Help purchasing a touch screen digitizer

      By mark249 · Posted

      Brought my 2015 Colorado into the dealership to check my touch screen issues, had that ghost touch thing happening. They said I needed a new touch screen and they could either order me one for $500. The lady at the service deck was nice enough to tell me I could order a touch screen online for less, she did stipulate that the touch screen had to be factory OEM, you can't pair an aftermarket screen to my radio seeing it was 2015, it had to be a GM factory OEM only. I found a few on Amazon and Ebay by the numbers on the back of the old screen, DJ080PA-01A GM# 22740886, Some said "OEM" in the description and others just said "Replacement". Would a replacement be the same as a OEM as long as it had the same numbers on the back of the screen? In some of the descriptions they also show different brand names but same numbers, is that an issue?

      I have both but typically use the 4 legged walker (wheels on front, ski's on back).   The four wheeler is starting to be used on "longer" outdoor walks.  The 4 legged walker is particularly helpful in practicing good walking posture.  Both of my knees are at different stages of recovery and I'm trying to not develop poor habits.  I can actually manage with a cane but it's very difficult not to favor one leg over the other.  My PT recommends I continue with my 4 legged walker for a while.  Yesterday was four weeks since my last knee replacement and I'm excited about my progress to date.  It has been a hell of a rough journey so far but it is exciting to witness  systematic and continuous improvement.  I went for years watching the decline of my "mobility".  It seems that everyday now I am alerting my wife to something I can do now that I couldn't a day or two ago!  I encourage anyone facing the prospect of knee replacement to share any concerns with others who have had the surgery.  It isn't an instant fix but rather is a considerable amount of short term pain for long term gain.  Recovery time and pain levels vary for individuals post surgery but the end results are typically very positive and I've never encountered anyone regretting having had the surgery.

      The lifter issue can be dealt with by shorter oil changes and quality oil IMO.
