I have a 99 integra ls and I think I might have bent a valve. My question is that can you bend a valve if you dont over rev. I drive my car everyday and never go past 4k. I'm pretty sure I bent a valve in my second cylinder? is it possible? i have 130k miles on my car. I just did a valve adjustment.


also... can you reuse a head gasket after you remove the head?

over revving wont bend valves, a broken timing belt or a timing belt that is loose could skip teeth on the cam gears and bend a valve.

Did it start running crappy after you did the valve adjustment?

its just starting missfiring all of a sudden one morning because the light started blinking. and then their was a ticking sound. I did a valve adjustment after the misfire and still the same. I dont think the timing belt skiped a teeth. What causes a burnt valve? maybe thats what i have. Everything is stock. I'm planning on changing the valves on this cylinder. I was wondering if I would be able to use valves out of another ls head. My car is complete stock and not sure why it did this all of a sudden.

Sounds like a timing issue. Deffinately check your cam gear(s) and see what posistions they are in relation to the crank at TDC.

no dont reuse a head gasket.

they timing is correct, when the tdc mark on the crank is aligned, the cam sprokets are allighned and face up. so not sure. I dont think its a timing issue because its only occuring in cylinder 2. When i unplug the fuel injector plug while its running, nothing happens. I already checked fuel and ignition system and its not the corporate. any other suggestion would be helpful.

check compression.

A bent valve will show symptoms primarily at low RPM.

In B-series engines, the exhaust valves can hit the pistons during an overrev.

yeah, im aware of what floating a valve means, i just dont think that this is the scenario here.

Sounds simple but did you check your spark plug gap?
Don't reuse head gaskets they are like 20-30.00
Technically you <U>shouldn't</U> reuse your headstuds either especially if you rag on it.

Definately do a compression test first and if numbers are low do a leak down test. Then you will know if it is the valves or the rings.
