You would have to undo what you just did. The head would have to come off and inspected for cracks. Possible head replacement.

Soi took off head now i have to take out camshafts and timing belt correct? Where are the valves located?

Would my timing belt breaking could it bend some valves in this particular engine?

The valves are in the head under the cam shafts.

How many miles is on it? If you have 60,000 or more it was getting to be overdue to be changed.

Yes it was overdue but some engines if a timing belt breaks then it wont hurt valves in this engine is the timing close enough etc to bend valves? And okay so in order to reach valces to replace them just remove camshafts and timing belt?

That motor is an interference engine were as some engines are not. Meaning in an interference engine, if the engine timing is off just a little bit, the valves will hit the pistons. There are valve springs and little keepers that hold a valve in. I don't think you can remove a bent valve without causing damage to the valve guides. You would not have the proper equipment to service a head. You would be better off replacing the hole head, camshaft set-up as a new unit. Then you have a good chance of pulling oil past the rings on the pistons with a new or refurbished head. Your in a no win situation, other than rebuilding the engine or replacing it.

See it sounds like there are too many miles on the engine to try an just repair the head without making it into a oil burner. The head, valves, and cam assembly is like $650 to $1000. Just not worth fixing unless you rebuild the hole motor.
