“I was out putting some more miles on the car to get ready for my track event at Road Atlanta Jan. 10 and 11… While making a pull from 35 mph, I accelerated and shifted short of redline, and boom — the car began knocking. I pulled over and popped the hood. I could hear a loud knock coming from the No. 6 cylinder area along with a serious, grinding, metal-on-metal sound coming from the supercharger area.“
Apparently, the catastrophe came by way of a failure in the No. 6 valve-train. It was enough to put the 6.2 liter supercharged LT4 engine out of commission. In fact, the dealer was explicitly instructed not to service or attempt to repair the engine. GM expressly instructed that the engine be shipped back to their factory for further analysis.
Valued at a replacement price of $24,000, the owner will get a brand-new engine installed in his car free of charge, as it is is covered under the warranty.
GM defines the first 500 miles put on the car as being the “break in” period, during which it is advised to only run the car under normal conditions. GM additionally advises that the cars not participate in any track day events until they have accrued at least 1,500 miles.
