Jumped Timing Chain

Hi I am after a little advice to find out how we could have bent valves in 2008 3.7 lt grand Cherokee. My wife had a front on accident in her 2008 Grand Cherokee. During the accident she revved the car and now two valves are bent. Would revving the car be enough to jump the timing chain and bend a couple of valves?

In an accident anything can happen it all depends on the forces applied to the body/frame/engine. If as a result of an accident I would have the insurance guy take care of all that crap and be picky. Yes it can happen but it is rare.

Thanks I have been arguing with the insurance company. they told me to take it to a mechanic and have them look at it and if he thinks it it accident related then they will fix it. Now the car is in pieces all over a workshop and they say there is no way that this could be related to the accident. I thought I would ask in case my mechanic was wrong. The car has only done 70,000 Km and was running fine before the accident.

70K Km is noithing a chain should be good for twice that distance but you are left with a mechanics decision.

the timing chain jumps when the impact hit, when she revved it then the valves bent. You need a motor.

I have had a talk with the assessor today. He has asked for a second option as he can not see how the timing chain has jumped. Having someone say that it can happen gives me more fight my mechanic is sure about it and the insurance company is saying very unlikely.
