hey i am looking at a eclipse that needs a timing belt that broke. i am wondering if it would have done any damage to the engine and what a estimated cost might be to replace belt or how hard it would be to do myself being in the automotive field and first timing belt i would be doing myself?

well , It ain't like puttin' a timming chain in a small block chevy considering all the accessories have to come off and there is zero room to work . chances are you bent some valves when the belt broke and that's the least that could happen . I'd price a decent junkyard head from a motor you heard running just before you pulled off the head . however you could replace the belt and then run a compression check ..... PBN
Typically the valves get bent when the timing chain breaks. Get a new head and it should be ok, but its hard to say what damage is there until you get the head off. They aren't too bad to work on though. Just get a repair manual and take your time. You'll be able to do it with no problem

if those valves get bent then youre in a bad situation...sometimes valves crack and the chipped pieces spread all over the head...and that aint the worst thing yet...

only thing u can do is line up all the sprockets and camshafts to the correct timing marks, put # 1 piston top dead center. replace the belts and try to rotate the engine using the crankshaft. at least 6 complete turns should be made, if u come to a complete stop and wont turn no more before the 6 turns then u bent a valve with the piston head or bent the rod

also when turning the engine using the crankshaft and a 1/2 inch ratchet it is best to take the spark plugs out to release the compression otherwise it will be very difficult to rotate
There is more to it than just bending a valve. If a valve contacted a piston, the piston can easily be damaged. It may not show up at once, but down the road, it almost surely will. It could hole easily, or you could find a bum rod bearing down the line. The best bet is to plan on an engine replacement.
Hey does the valves get bent on the v6 or is that a 4cylenor?
