Yes,your 2.4 engine is a interference engine,the mechanic should of showed you the bent valves and not installed the timing belt.Did he tell you they were bent when you paid or you found out after you drove home.I would go back and demand money back,if he's won't pay back,go to the BBB and report him and take him to small claims court,your engine is bad.

Hope these help

will it go over 2500rpm in neutral? if it will then it sounds like a throttle problem if so check all linkages, check air intake system is sealed. ask a dealer to have a look if all else fails

Faulty sensor switch in the water jacket.

My 2002 chrysler PT Cruiser engine Rev's itself about twice when i just start the engine. What could be the problem?

What kind of spark plugs did you use??? Here is a list of plugs that you can use on your Turbo engine.

Champion
* Copper - stock # 440 - RE14MCC5 (OEM)
* Copper - stock # 470 - RE14MCC5 (supercedes/replaces # 440, but some catalogs same part #)
* Copper - RE16MC (supercedes/replaces RE14MCC5 and new Chrysler recommended gap is .040)

NGK
* Copper - LZTR4A-11 (supercedes/replaces RE14MCC5 and new * Chrysler recommended gap is .040)
* Copper - stock # 4306 - LZTR5A-13 (one range colder)

If you use the platinum spark plugs used on the Non-turbo engine, they will start to glow and cause misfires and can cause engine damage to saver detonations throughout the RPM cycle.

As for the over heating, you could have a blown head gasket from a severer detonation if you notice coolant and oil mixing in your engine and coolant tank. The less cause for over heating wold be a bad thermostat or a faulty radiator cooling fan, cooling fan relay or cooling fuse which is located in the engine compartment fuse box by the battery.

Good luck and thank you for using Fixya.

check if engine fan is turning on and off...could also be ahead gasket leaking
