Looking online for used low mileage, GS or Z06 in my general area. Come across a GS 2LT 7M with only 6xx miles on it. Priced OK, and only been in service for 3 months.



Sound good? Well, it did until I opened up the Carfax report.................

53 miles



Maintenance inspection completed
Valve lifters replaced


Whats up with that????? Owner obviously got scared enough after the repair that he just dumped it. Can’t say that I blame him.

Possibly something like a lifter failure like KenHorse just dealt with.

KenHorse

Over 1,000 miles since and all is good

Either failure or did the owner perhaps over rev and collapsed a lifter?

Can you link the thread about your issues Ken? Thanks

Not such a "serious" issue, at least compared to stuff like crankshaft/bearing/bottom end replacement, transmission replacement etc.
If an extra discount/compensation is included in the final price then no tremendous reason for concern.

Here is Ken's thread, post 146 has some pics:

Serious enough that a brand new engine had to be somewhat disassembled and repaired.

There is is no extra compensation offered far as I can tell, and the price is decent, but by no means a great deal. (Who knows what they would sell it for though).

Dealer is posting the Carfax, but you gotta wonder if a potential customer didn’t pick up on it, would they mention it?

Key word there is "somewhat" as in lifter replacement not too serious as compared to other repairs I mentioned.

My 2 Cents...Metal mixed with bearings ain't good.Depending on the condition of the replaced parts and the amount metal that went threw the various oil passages?
Would be of a concern of the longevity of the engine after the fix.
If their was pictures from original owner that showed the replaced parts? If not badly damaged that would give me more confidence on the purchase.
Do you plan on owning after warranty? Can you purchase extra warranty?
Maybe a deal can made to include extra warranty coverage?
Their is alot of good deals out their for New without out issues.Hopefully.
Good thing you checked

If you do not feel good about purchasing the car after knowing what you know, pass on it. Plenty of cars out there that have no issues and can be had for a very good price. However, you can see if a better deal on that car can be had - extended warranty, more off the price, etc.

My take is there are plenty of excellent used C7's available that don't have a 'story' that comes with them. And it just doesn't make sense to buy a C7 with early engine problems when you can buy one that hasn't had an issue. A lot of issues with new car show up early, so if you find a used car that's been great for the original owner then you'll have a better chance of getting a good used C7. I guess the exception would be if the selling price were well below the blue book

Don’t get me wrong, I have no intention on buying this particular car. I would have been very interested if I didn’t find out about the issues. Extended warranty or not. ANY issue with a literally brand new vehicle is bad mojo, never mind engine issues.

My biggest concern for any potential buyer is that they either won’t see the Carfax or Chevy report, and the dealer (who does not sell a lot of Corvettes) won’t speak up about it. I could be totally wrong, and I sincerely hope I am, but I sure would not be happy if I was that customer and found out down the road.

A) That C7 will in all likelihood be fine and never have any other issues related to the lifter replacement.

B) I have a hard time feeling sorry for those who don’t do any history or homework when buying a newer sports car, not even a simple carfax which most reputable dealers will provide for FREE if asked.

C) if the next buyer didn’t care anything about the car’s history at the time he buys it, why would he care so much later?

Move along. Nothing to see here.

nothing new or surprising here, google AFM lifter failures. There will be more (except on the 2019 ZR1, where the AFM valve lifters have been removed by GM.) its been in all the funny papers for years. Coming soon to courtrooms near you: Class Action Suit #7, AFM valve lifter failures

AFM lifter disabling.

Is this the ELB 2LT currently at herlong chevy in SC?

KenHorse

Or...if you have an M7, simply never go into ECO mode

Does this mean we need to remove some oil if using Range Technology to disable the AFM?

Install an AFM Disabler

An AFM Disabler is an electronic device that plugs into the OBD-II port, under the dashboard. It prevents the computer from switching over to four-cylinder mode. It’s a simple and effective way to turn off the AFM system and provides the added bonus of improving exhaust sound.

NOTE: A disabler device should ONLY be used if the valvetrain is in good working order.

Engines with AFM use a high-volume oil pump. When you eliminate the AFM system, the extra oil is no longer needed. Excess oil will be pushed out of the pressure relief valve into the oil pan. This will spray oil on the bottom of the cylinder walls which can cause oil burning, especially in high-rpm engines.
