problem with valves

[hippy]

my friend has a gtst and said that a valve in the engine cylinder 5 has a little dent in it ... need to know what kind of problem is this?? how critical is it?? does he need a new engine??

thanks for your help, i know the info so far is pretty vague ... but thats all i know for now.

hmmmm question's 1: how does one dent a valve 2: how does he know has dented it without pulling it to bits..... are u sure he diddnt say BENT????? chances are if its from a timing belt associated problem there will be a few more than just 1 bent valve...if thats the case the head will have to come off and replace the valve and cut a new seat into the head ...... normal everyday stuff but not exactly cheap...... good luck dude...

My valves had slightly little dents or marks but are ok.

I'll see if I have a pic laying around.

Here's the pic.

I had the head rebuilt ported/polished.

All the valves so I am told were checked out and A O.K.

The little dents that form a circle approximately half way in to the valve.

Dents occur when the piston hits a valve softly. they bend if they are hit hard.

Will happen when the timing belt breaks, or the timing is incorrect, such as when i did the water pump on my alfa and bent 3 valves cos of my excellent workmanship $1500 (

but theres nothing wrong with dented valves is there?? engine will last a while yet right?
