YOu mentioned that it was good since new but if new means new to you: Warranty may be valid:

I would inquire if the engine, oil pump may have been defective from the factory. Get GM involved at that point and see if they'll cover. If you don't ask/try you'll never know!

 

good advice. Take it one step further with GM and show them your service history. If all oil changes were performed on time and properly I am sure GM will at least want to know the "Why" this happened and may offer some resolution.

 

A 65,000 mile engine with a DEFECTIVE FROM THE FACTORY OIL PUMP? C'mon man. Maybe it failed but that is far from being defective from the factory. This is really stretching it...

Truth is, manure occurs. That is exactly why you buy the extended warranty (if you can) or you don't and take your chances.

 

If I had to shell out 10k I would trade it in on a new one or get an aftermarket motor and good luck with your decision

 

Mine is in the shop as I type getting the oil pump replaced. 2009 with 15 thousand miles. Truth is, there are defective oil pumps from the factory. Mine was in the driveway with erratic oil pressure then to zero then stuck at 37psi. I called the dealer & car flatbedded to the shop. Should pick it up this afternoon. This is what I was able to research.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:

Some customers may complain of low oil pressure, no oil pressure, and/or engine noise, which may be the result of a sticking oil pump pressure relief valve. In some instances, this may occur intermittently if the valve frees up when the engine cools down.
Recommendation/Instructions:

If SI diagnosis isolates low mechanical oil pressure at the oil filter housing and oil pressure sensor, replace the oil pump, flush the oil cooler lines (if equipped), clean the inside of the oil pan, change the oil and filter, and re-evaluate the concern.

Notice: If an engine noise is noticed after replacing the oil pump, follow the SI diagnosis and repair the engine as necessary.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

 

Hi guys so here is the latest. The dealer called me yesterday and talked to GM about this issue. What they came up with is this, GM is willing to pitch in 4 grand towards the total of ten to fix the car. The kicker is they want to take the engine apart and check for "abuse" before they go ahead with this. However, they want to charge me $1700 for taking the engine apart if they do find signs of abuse. What do you guys think?

 

first off, I think you're "barking at the wrong party" re the Lingenfelter thing and the person who said it. second, you don't say how you've driven the car or if you've abused it, but I'm getting an impression...maybe you roll the dice and wind up paying 1700 for nothing. wouldn't surprise me.

 

Well, we're talking about an '06 with 65k miles and no warranty, not an '09 with 15k miles and a 5yr/100k mile warranty.

 

Hi AO, Lol I am not worried about the abuse part. I barely drive the car above the speed limit and almost never get on it(although I have every once in a while). I guess the part that I am concerned about is if they are pulling a fast ball on me and just trying to get more cash out of me. I really doubt they would do this considering I have taken and bought some of my cars there for 10years or so. I do however see how you could come up with that conclusion though since I havent really posted anything about my driving habits. I will meet up with them on monday and talk with the corvette tech and make my decision from there, but I dont really think its unreasonable of GM to search for abuse considering what some people do to these cars. BTW the car is completely stock and has never seen a aftermarket tune.

 

As far as you know. I'd be a little concerned with the previous owner...

 

I've had a couple of warranty and good will issues in the past with dealers and all have held to their word. I would however find out what definition of abuse they are going by and maybe jot down a little agreement to check off and sign just to be safe.

I certainly would get the 1700 rolled into the goodwill gesture.

 

I never thought about that.... I bought the car with like 2000 miles on the clock from a man that was about 50+ and didn't strike me as the type who would mis treat a car, put a tune on it, or just simply not tell me I did spend a fair amount of time with him so my opinion is just based on first impressions... But i guess you never know.

 

From that description I wouldn't worry about him then. Something would have probably showed up during the amount of mileage difference.

 

No, I don't think they're just trying to get an added 1700 out of you. And as RL says, if it proves to be not your fault but something else, I'd ask them to roll that into the discount and count it toward the engine rebuild (if that's what they're going to do). I don't think that's unreasonable at all. Frequently, shops charge a diagnosis fee, and if you get the work done there, it's discounted from the cost of the service.

Still, you are going to be out $6K plus or minus for a new engine. Wow.

 

Even with the 4k off it still seems high. I have to believe that you live close to a good corvette tuner. I paid 6k for my forged motor. Good luck

 

Hi, you are correct. I am not really looking for any high horsepower application and really just need to make sure I have a reliable car. I found next level performance isnt to far from me and they seem to have a decent reputation. I shot them an email and waiting to hear back on what they have to offer just for the hell of it, maybe a built engine would be cool

 

Hi, abuse also covers lack of oil changes and maintenance...something to remember. I don't think GM would try to pull a fast-one on you but, dealers could be shady. You state you bought 3 cars from them and they seem ok to you then I say go for it. $6000.00 is not a bad price for new GM parts and labor. You could have the same work done a little cheaper but, is it worth the risk to save $1000 to $1500 from someone you don't know? You also have another option to install a used motor for about $2500 and installation labor fees. Good luck!

 

I would pull the motor, resize the rods, turn the crank, slip a cam in, and check the heads and bore. You will be well under $10k, if you knew how to spin wrenches I bet you could do it for the $1700.

 

Car is worth about 27k. Putting a new motor in it is 10k? If the car runs aim it at a wall throw a brick on the gas and have the insurance company get you a new one.. J/k sorry about your situation and good luck.

 

Well are we talking about defective oil pumps or mileage & warranties? Fact is, the LS series engine oil pump is designed to last the life of the engine. An oil pump failure at 15k or 65k is a defective pump in my opinion. If the OP bought the car new and had purchased an extended warranty, I'd be willing to bet the defective pump would have been replaced. But, manure occurs.
