[VIDEO] The Corvette Mechanic Paul Koerner Goes to Work on a Grenaded LT2 Corvette Engine

It’s been a little while since we’ve last checked in with The Corvette Mechanic Paul Koerner, a GM World Class Technician for Key Chevrolet in Middletown, CT. One of our recent videos showed Paul as happy as a kid on Christmas as his dealership received the special tools needed to service the C8 Corvette. In these next series of videos, we’ll follow along with Paul as he puts those special tools to use on a C8 Corvette with a blown engine.

Paul introduced us to this Sebring Orange Corvette late last week with a video on his Facebook page. Introducing the project, he says “What we have is…pieces. And unfortunately, these pieces are part of an engine,” as he shows pieces of a piston that grenaded and blew holes through the engine block and oil pan.

While many of us are keen on knowing how and why the Corvette ended up in the service bay, Paul confirms it wasn’t valve springs as they are all still intact. As the car is under warranty, GM will be sending in a replacement LT2 engine along with the wiring harness which was also damaged in the incident.

As a GM service technician, Paul says his job is to return the vehicle to factory-engineered specifications and not “split-hairs” about how or why this incident occurred. He says, “It’s my job to get this thing exactly as it was when it rolled off the assembly line, and that’s exactly what I am going to do in this case.”

We’ll be following the Corvette Mechanic as he updates us on this project. You can see more from Paul at The Corvette Mechanic’s Facebook Page, or visit the CorvetteBlogger archives for previous blog posts featuring Paul Koerner.

  1. Wow — “grenaded” is an apt description in this case. Wonder what caused the engine to incur that kind of damage?

  2. The GM service “technician” might not want to know what cause this engine to grenade, but the rest of us (and GM) does.

  3. Curious to know if the owner was aware of and followed the owners manual break in period instructions? Asking for 25,000 friends.

  4. Ah yes, the bargain car rears it’s ugly head. What would that repair bill be out of warranty? My guess 16,000.00.

  5. @ Mako: Most Likely that Paul must follow protocol to send the engine block back to the engineers Un-open for investigation…
