C7 Valve Cylinder issue
Took my car to the dealer after it wanted to give out on the highway pulled to side and shut it off and when trying to start It wouldn't took it to the dealer and couple days later they tell me it's a valve issue in the cylinder and lookin more in to it to see what else is wrong
Is this a serious problem
should I be Asking for a new engine or have them fix it would there be future problems only 1200 miles

Did it make any strange noises when it decided it didn't want to start? Like metal on metal noises? There was another recent thread about a busted rocker arm. Hopefully it's similar. If you have a valve in the cylinder (as in not in the head anymore) then you have a crispy motor. You'd probably know which of these possibilities it is, as a dropped valve would sound really bad if it didn't outright seize the engine. A busted rocker would make it run on 7 cylinders but probably wouldn't sound nearly as bad..
The thing that worries me about the potential broken rocker is whether the actual arm is broken somehow or it let go of the trunion bearings which means a mess of needle bearings in the engine.

Another tread in the general forum about a broken valve spring. Said the retainer kept it in the head - I would want to see for myself thru a scope to make sure it didn't contact the piston. Whatever yours is, I hope it's as painless a fix as possible.

What you want a new engine, you don't want something that has had internal damage done to one of the cylinder walls.
If the engine stopped it was because the valve jammed the engine so there has to be head and wall damage.
I wouldn't worry about matching numbers I think all that nonsense stopped years ago.

"Numbers matching" is for 50 year old Corvettes to prove their originality which makes them worth more. I think there are twice as many numbers matching '66 427's running around then were made that year. lol
