I broke my timing belt on my 2000 hyundai accent i took off the timing belt cover and the belt was mangled and the line up marks were off i then took the plugs out and found out that my forth plug was damaged a little bit internaly so i then took off the valve cover to see if i could see any valve damage i dont see any so i try rotating the crankshaft and i can only move it about a quarter and it stops what kinda damage am i looking at and how much to fix

Make sure those 2 marks are alligned durring reinstal

Did you line up the timing marks when you installed the new belt?

Timing marks are in the circles. Make sure belt is tight on right side when marks are aligned, then release tensionser to take up slack on the left side. Thanks for using fixya.

lots of possibilities. sounds like you may be out 180 degrees.
im thinking crank probably needs cylinder 1 at top dead center and then line the marks up.
best to double check the book.

1st you may want make sure that's not an interference engine. if it is then chances are the valves are bend in the head. changing the timing belt probably won't help then. If its not an interference head, then you would need a timing mark diagram which can be found online. be very careful that all marks are aligned. when finshed installing the timing belt, rotate engine by hand twice and re-align marks before putting the rest back together! hyundai should be able to tell u if the engine runs interference or not.

have diagram can email you need email address to send to, also is it a L Hatchback, GS Hatchback, GL Sedan

yes those are the marks and it sounds like its not in timing

first thing i need to know is did the timing belt break?
second is are you sure you aligned the timing marks and after the belt tensioner was tight you rechecked to make sure the timing stayed where you had it.
next step would be a compression check to if a valve was bent whenchanging the belt
i have seen this happen and this engine is an interferance engine.
