Oil Pump failure

[07Softail]

Soundds like a good possibility.

If it's the vacuum pump this has me wanting to put the Vette electric vacuum pump on and removing the belt driven pump!

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 the oil pump. They dropped the pan today and found shavings. GM has approve to tear into the motor; I was told that they will be rebuilding the motor and possibly getting a new block. Just got the news today so we will see what they find. Seems like they are working with me

 

 

Wow. Would be further ahead for them to just install a crate engine into the pickup. Tearing the motor down and rebuilding, along with a new block, would cost more in labor than just yanking out the old motor and dropping in another.

Scary that a 130 dollar part on outside of engine can destroy a good engine with no warning .

Wouldn't that be covered by the 5 year 100,000 mile power train warranty?

Vacuum pumps are only 36K mile according to another thread of engine failure on this page

[Colossus]

so it's part of the engine yet it's not so it won't be 100,000 mile warranty?

I think only internal parts are Covered. On the 100,000 mile warranty.

The vacuum pump is an accessory, like an alternator or water pump. So it's not covered by the powertrain warranty.

 

Only the powertrain is covered to 100k for the 2014-15

And only 60K powertrain for 2016-17

[paumat]

can someone explain what the vacuum pump failure has to do with oil pump failure. Does the vacuum pump drive the oil pump?

[pickmeup]

Seems like if vacuum pump fails it sends shards of metal into engine and thru oil pump leading to engine failure I believe.

[15_silverado]

^^^

Yes

The vacuum pump is lubricated by a feed line from the engine oil. So when it fails it can send metal shavings into the engine oil, killing the oil pump and engine.

 

Now the Corvette uses an electric vacuum pump that is obviously not lubricated by engine oil, so if it fails no harm would be done to the oil pump or engine; you would just loose power brakes; you would still have brakes just harder to push, no power brakes.

So why did GM just not use electric vette set up and save truck owners the risk of losing good engine over a 130 dollar external part .....crazy

[Colossus]

Because that would be too easy..

Hello, I have a 2015 GMC 1500 Denali 5.3L with 34000 km on it.

 

I took it into the local Dealership (which is where I purchased the truck from) for some warranty work before going on vacation.

- Running boards

- Wining sound in engine compartment

 

The following day, I received a call from the Service Advisor I was working with and he advised me that the oil pump has failed and I need a new engine and that it was not covered under warranty.

 

When the truck was about 6 months old, I purchased an aftermarket programmer and installed it to potentially extend the life of the transmission and hoped to solve the problem with the initial bogging of the engine whenever the accelerator is pushed. (bad on me and I will never do it again)

After 2 months of installing it, I saw no value in it and removed it after bringing everything back to factor settings.

 

The service advisor continued to state that due to the programmer that was once installed, GM has put a Powertrain Warranty block on my truck and that I would need to pay for the repairs.

He proceeded to give me a quote to replace the engine, Radiator, oil cooler and oil cooler lines that came out to be around $14K.

 

The biggest problem I see here is that the dealer made no attempt to determine whether the aftermarket part caused the problem.

I asked him how they determined the failure and if they dropped the oil or inspected the oil filter for contamination.

He said no we don't need to, basing it strictly on the sound it was making.

 

I took the truck home and proceeded to change the oil and taking a sample at the same time. No metal was found.

 

I called the 800 number to GM Customer Pound Sand Department and spoke with a lady there and told her my story. She offered me some hope by saying that she would look into this for me and get back to me. That was 8 weeks ago....never received a call back. I made many attempts to call her and left a pile of messages for her to call me but to no avail.

 

The story goes on and on.....

 

On July 28 2017 I received a call from the Dealership about my truck and asked me all of the details of the past 2 months. I now have an appointment with him and the Service Manager on July 3rd... maybe something good will come out of this yet....I will let you know

Good luck man. Unfortunately many manufacturers have stipualtions claiming any non OEM tune will indeed invalidate the factory warranty. Because of this when you installed the tuner it places a log entry in the engines computer bank which a dealer can access. Since your warranty was voided by tge tuner, the manufacturer no longer hasto prove the invalid tune caused the oil pump failure...your warranty ceased the very moment you installed the tune. Maybe GM will work with you, but their liabilities are outlined in their warranty manual manual.
