My daughter was coming home from college in her 2002 PT when her timing belt broke. Dealer told me $1400 to fix, mechanic in town told me $650. Both told me this would just get the car started and that they wouldn't know if the valves were damaged until this was fixed. My question is, should I take the chance on this fix and hope the valves are fine or just replace the engine?

In most cases on this board it's been reported that the valves were okay. They should clear valve to piston but may have valve to valve interference. How is the rest of the car? If good, I would go with repalcing the belt and also do the water pump at the same time.

I agree with Cudapete.

How many miles are on the car?

There is a post on here somewhere, where somebody actually had the head off and moved the cams to verify that there is no valve to valve interference.

$1400 is steep, $650 isn't bad.

I've done it to my PT twice, once to change everything and again to line up the cams correctly. :facepalm:

The second time it took me about 4 hours total, but I didn't have to change the water pump or tensioner the second time. I'm ready to replace the belt again as I passed 199,000 miles yesterday, so hopefully I'll get it right the first time this time around.

The valves should be fine unless she was at redline when the belt broke. Mine sheared teeth off the belt at idle and I didn't have any problem, and when I ported the head at 35,000miles I moved both cams at different angles to try to get the intake and exhaust valves to touch each other and couldn't. So unless the rpm was high engough and the vavles were floating, about a one percent chance of there being a problem with them.

The Gates timing belt website lists the 2.4L engine as a 'non-interefrence' engine ( the valves can't hit the pistons due to mis-timing). I have heard that intake and exhaust valves can hit together in a mis-timing event, but this would be a rare instance.
It's easy to check for bent valves without pulling the head. Just remove the rocker shafts under the valve cover, this will close all valves and keep them closed. Then do a compression test.
