I have a 90 accord dx, f22a. Water pump seized, broke timing belt, possible bent valve. I'm not sure if valve is bent yet. If one is, should I replace all the valves at the same time? Does any one know where to find directions, any tips?

 

If you replace the belt/water pump without checking the valves first, use a compression tester to check each cylinder. Otherwise, you may try a leakdown to determine how many valves are bent without the timing belt on. Probably time for an H22.

 

what are the symptoms of a bent valve or a burnt valve?

 

It's not a possibility. The Accord and Preludes have interference engines which means if the timing belt snaps or slips off, then you're not worried about bending a valve, you're worried about how many you bent. Only way to find out, compression check or pull the head. Either way you'll find the same scenario...bent valves.

 

Yep, bent valves are virtually a certainty, unless you were coasting at like 5mph when it happened

 

don't even think about compression test, just pull the head up and see, if you do a compresion test you mind bent more valvules

 

I've come to the conclusion to just replace the head altogether. Is there a possibility of piston damage as well?
