Does anyone know the cost to replace an oil pump on one of these motors?    Out of warranty? 

I was told I could do it for 4-5k but it's honestly more effective to do a motor swap for 5-6k because of the damage that can happen from the oil pump failure.

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 .

Am I missing something? Further up the page someone said $130 part which is external to the engine.

I would also like to know what is involved if changing as a preventative measure & if the part has been redesigned or any aftermarket parts are preferred.

They are referring to the vacuum pump failure which causes a low oil pressure light. I'm talking about the actual oil pump failing which is at the bottom of the motor.

It looks like it is external but probably a bitch to get at, I'm guessing pulleys need pulling which probably requires a load of stuff out of the way.

Hi All.  I am a new Member to the group.  Hoping for some feed back....   I have a 2014 Sierra with 98,000 kms.  Recently had my Oil Pump Replaced.  This is how the events that lead up to this started. Lets note that the week previous to this my truck was in at the dealer for a regular oil change.   I 1st noticed a whining sound from engine, almost sounded like a power steering pump on its way out.  I chalked this up to it being cold outside as Motors make odd noises in extremely cold temps. At the time we were under a polar vortex in northern Ontario -35 degree Celsius all that week. I did notice my oil pressure gauge fluctuating more than normal to.  A few days went by then my check engine light came on.  The dealer was closed, so I went to my friends who owns a local garage to see what the code was on his OBD2 reader. It was PO6DD which is oil pump.  That night the check engine light went out,  but truck still had whining sound.  I made an appointment to bring truck to the dealer that week.  Luckily the engine light came back on before I took it in.  They called, and said oil pump needs replaced, and will be covered under powertrain warranty.  They provided a loaner, and had truck back in a week.  Part had to be brought in from the US. On the work order it showed they replaced oil pump, seals, and gaskets, coolant, oil/filter.  After reading some of the people who had same issues here on forum, it leaves me a little worried.  Some people had a new engine replaced, or metal shavings found in oil, valves replaced, ect...   What if the GM tech didn't look into all these things, or look at things like the oil, and if it had metal.  Keep in mind this is a small dealership in a Northern small town . I am sure they don't see the extent of repairs like a larger dealership would in a bigger town.  Just a little worried and paranoid right now.  My powertrain warranty ends in Aug 2019.  Engine could go after that is up, if motor wasn't properly assessed from the oil pump failure. My truck seems to currently run OK. Oil pressure seems fine again.  Sometimes I swear I hear the whining noise I 1st heard before oil pump was replaced when I 1st start the truck, sound goes away in a few seconds.  Or now wondering if the truck always made that noise when starting, and I just didn't notice?  Am I just being paranoid?  Any feedback is appreciated.  Thanks for Reading folks.

Interesting.   I had basically the exact same thing happen, same code, etc.   Noise started when it was  -20 or colder and I chalked it up to the cold.   Only difference is mine eventually grenaded. 

 

I do wonder the same thing.  I've got 300 miles on the truck since I got the oil pump replaced (was done at a local shop).   They said everything looked clean and they didn't find any shavings etc.   They do want me to change the oil again in 1500 miles though.  Unfortunately mine wasn't under warranty and cost me a little over $2500.  Truck seems find now however I do question the longevity of these things.   For a 2014 pickup, I've stuck way too much $ into it.

 

Here's the thread on my issue -

I'm curious,  what's your oil pressure's  cold and hot with the new pump?

Cold idle is around 50-55, warm idle is 38-40,  driving is around 45-50

My cold idle with new pump is 40-50. Warm idle is sometimes 20-40.  Driving is 50

I'd buy a powertrain extended warrantee (preferably GM) asap.

      Silverado 4500-5500-6500 are they still being produced? Would have sold better as GMCs as well

      By C/K Man · Posted

      There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.

      Software Update

      By nfisherman · Posted

      I have a 2026 2500 HD Ultimate. My phone app says there’s a software update available. It’s something about improved battery management and something to do with the running boards. I follow the instructions for the update but the “Check for Updates” option is greyed out in my settings menu. Has anyone else seen this? How did you resolve it? The help message just says “see your dealer” if the download doesn’t work. I’m just trying to save a trip.

      Exhaust Question

      By newdude · Posted

      Fuel mileage?  That's all how you use your right foot.  Exhaust will give you sound.   Stock exhaust 5.3 is 2.75" diameter piping.     If the truck is nice and worth putting some $$ into it, I'd go for a Corsa catback.  I had one on my 2019 old body 5.3 and it was just perfect.  Zero drone, just driving around and cruising on the highway you'd think it was stock, but when you opened it up it was like a Camaro with the factory dual mode.  Corsa bumps their catback to 3in diameter.
