Since the engine still runs we can eliminate a broken timing chain

 

 

I guess that came out wrong

 

***update***

they ran the computer diagnostic and there was no record of the amount of rpm's that the piston hit the head and valves. fidelity is now sending an independent inspector out tomorrow to asses the damage with the repair team at the dealership.

 

i think you're sol

 

Odd though that the CEL didn't go on before hand.
Did they take the head off before they concluded that the piston got hit by the valve? Valves can bend and therefore lose compression in teh cyl without actually colliding with the cylinder.

 

So let me get this straight, you over revved your car a month and a half ago and you don't think that could have eventually manifested itself into the problem that you're experiencing now? When the car is over revved it won't always show signs of failure, sounds to me like you cracked a retainer over a month ago during the over rev and it finally let go.

 

Got word on the car. They need to take the top engine apart and look at the heads and the internals of the engine. Of my understanding, if the piston is notched, then the piston collided with the valve and therefore over-rev caused the engine to stop working. The manager told me that once the car gets over-revved, the engine stops then and there. He said that the problem can't build up over time. Do not know the logistics of that from reading everything on the boards. That means driver error. I will know by Monday or Tuesday on what the verdict is. Still don

 

If its a massive over rev and you let the clutch all the way out it would happen quickly.

Most over rev's are a wrong shift and you kind of realise / catch it half way through the clutch travel, as you can hear it. It still over revs but not as much, and therefore the damage is not instant.

Depends what you did.

 

..............is there anything on the internet that states that an over-rev can happen...snow ball into a problem to where this happens. they are claiming that by looking at the piston they can tell that it was over-reved which would cause the engine to not work immediately.
