[VIDEO] The Corvette Mechanic Paul Koerner Finds a Surprise in the Blown LT2's Intake Manifold

Continuing on with the Corvette Mechanic Paul Koerner and his C8 engine swap project that he’s performing at his dealership, Key Chevrolet in Middletown, CT.

Paul is preparing to install the replacement engine, but first, it’s time for a little “remember when I said” moment from the GM World Class Technician.

In the fourth video of the series, Paul was showing off the new intake manifold that would go on the new engine. Asked why he would change the intake manifold if it was the bottom end of the engine that blew up, he says that per GM’s service guidelines, if there is debris in the engine and the intake opens up, you can end up with broken parts getting sucked up into it.

Well, now that the old intake is off the blown engine, look what Paul finds:

  1. Unbelievable catastrophic failure! The amount of labor, price of replacement and lack of faith in the LT2 engine should give C8 buyers pause.Never have so many issues appeared in any previous Corvette engine.

  2. Thank goodness the owner has a great tech that goes the “extra mile” to ensure the new engine is “done right”

  3. No way would I accept an engine replacement in a new car. Especially a jigsaw puzzle like a mid engine corvette! A new car should be given and defect studied at factory. These units at being built too fast from point one on through. No excuse. They are selling dreams , not nightmares!

  4. How about a foreign item in the intake causing a blown engine? Had a customer bring in his 1972 Corvette with a blown engine; RR cylinder had a rectangular hole smashed thru the head. This caused coolant to instantly flood the cylinder and hydrostatically lock the engine up. Good thing car was an automatic, customer was carving corners on a winding road (engine lock up with a manual would have flung car off the road). Item was located, the blade of a snubby screwdriver. In fact the valve train had chopped the blade up and was a total of 3 cylinders and the plastic handle was melted into the manifold. When presented with evidence the customer went back to the idiot that he had work on the carburetor to fix it: yes, that was a mistake. A couple of comments to the above responses: any car can have issues, it is built by humans; GM is taking all affected parts back for analysis to determine cause of failure; mid-engine cars are by nature much more complicated in design and hence maintenance procedures can be challenging. The C8 is amazingly well laid out for such a modern car. To visit true mechanical hell, try high end German or Italian cars.

  5. Can you imagine if that intake would have been installed on the new engine? Crunch, Crunch! UGH!!

  6. The LS series of engines were far superior in durability and reliability. The LT series are more powerful, but also far more complex as well. And that unfortunately makes them more prone to fail.
