I have a 1991 eagle talon (2.0 turbo that the timing belt snapped and hit the pistons. I was wondering the exzact damage. I of coarse know that the head and timing belt have to be replaced however how does this affect the pistons. I can see where the valves hit them. Will this affect the engine afterwards?

It depends on how bad the pistons hit. Put up some good close up pictures of each piston. It will create a weak spot in the piston, if the car is only going to be pretty stock, they are normally ok with a light hit. You will want to file down and polis the lip that was created with the hit. It might be a good time to freshen the engine and put in some 2g pistons too.

bent valves, split valve seals, etc, etc.

If anything chipped off a valve you'll have scored cyl walls and maybe a cracked ring.

Like Jet said, it depends upon the severity of the hit. I've seen pistons cracked from valves slamming into them, and I've pulled apart perfectly running engines and seen valve damage on the pistons from previous repairs.

What do you mean split valve? The head of the valve came off? If so then the head and pistons are probably junk.

I think he was talking about cracked valve seats, which I have not seen yet from "just" bent valves. The bottom of the valve guide will crack if the valve is bent enough, but I do not think the valve seal would be damaged unless you had a keeper/retainer issue.

Well here they are!! Doesn't look like engine is damaged. You see all pistons, the broken head, and the new one
