Motor locked up while in the shop for intake replacement.
About 2 weeks ago I got a P200A code, so I took my truck to a shop for diagnosis. They recommended replacing the intake. The intake came in Monday and they started the repair. The truck was supposed to be done Wednesday, but after they put everything back together it wouldn’t start.
By Friday they tore the motor back down and told me the engine is now locked up because carbon supposedly fell into a valve and the piston hit the valve. The truck never ran after the repair attempt.
There is also now a pretty noticeable scuff/dent on the fender from what looks like removing the battery during the work.
The shop is now asking me to approve a replacement engine. I have never heard of this happening from an intake replacement and haven’t found many similar situations online.
Can carbon buildup actually cause an engine to lock up like this during startup, or does this sound more like something went wrong during the repair/reassembly process? What are my options? Any insight is greatly appreciated.
