These are rebadged Mitsubishi Eclipse vehicles and use Mitsubishi engines, and yes, they are "valve benders." If it only jumped one tooth, you might not have a problem, but if it jumped several, plan on a reman head.

"Float the valves" isn't really the proper terminology for what happens....but I get what you are getting at.
The answer is: Usually / Sometimes
I know that answer is kind of vague but depending on the circumstances, if the engine "jumps time" you have a VERY good chance of having the valves contact the top of the pistons. When this happens, the valves bend. This usually means that a new (remanufactured or salvage yard) head is in order. On rare occasions, this doesn't happen and just a timing belt is in order but for the most part, you can safely bet if your engine has jumped the timing belt, you are going to need to replace the head....
Please Note: Some engines are called "Non-interference" engines. In other words, if the timing belt breaks, the pistons will not contact the open valves. From experience, I can tell you, 90% of the time, these engine DO in fact, bend the valves.
Hope this helps....

Bending a valve from contact with the piston isn't very common even in an engine that is labeled an "interference" engine. When this does happen it is usually when the car is running highway speeds or higher Rpm's.
If a piston does make contact with a valve it usually makes the most sense to do a complete over-haul so as to not put a remanufactured head on a motor with a damaged piston, connecting rod, connecting rod cap, or rod bearing that can be damaged but not visable from the top side or outside.
Most jumped timing will immediately stall the motor and will not be so far off that there is contact between the valves and pistons. It just quietly dies and will not restart.
Good Luck!

I believe these are interference engines, and if it only jumped one or two teeth you will be fine, but if it broke or completely came off you are in trouble. The only real way to tell without ripping it apart is to do a valve leak down test, much more effective than a compression test in this case. Good luck!

You will need to do a compression test to see if you have bent your valves.. If so time to look for a newer car unless you have a free spare engine in the back yard...

Goofs up the engine--the up and down motion of the valves and the up and down of the piston is out of sink. Could bend the valve or knock a hole in the piston... It should not be running very good...

i recently put a timing belt on a laser . the belt broke and i just put a new one one fired it up . it was rattlingfor a bit and then as it wsa sitting there idling it the rattle went away. you do more damage if you tyr cranking it over and over after the belt broke
