Oil Pump failure

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.

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.

32 being the pump I take it.I have changed my vac pump before my oil pump packed it in thinkin that what the weird growling noise was.The vac pump wasn't too bad to do on my 4.3.The oil pump being on the outside front may not be as bad either but I havent had to do one yet.

I have never priced it out personally.

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

Thanks ,  big difference

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.
