Oil pressure.

Herminshs · February 21, 2020

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.

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

good decision, it may suck at the time but it is even worse if your sitting on the side of the highway. tlaw91 could you post the bulletin on this problem

Herminshs · February 23, 2020

I won't hear back from the dealer until monday at some point, I will post whatever they find

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?

durandetto · February 23, 2020

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.
