i removed my head tonight and found the exhaust valves are pitted, is this normal or should i look at replacing them.

did you do a compression test before the head was removed?
i think leaky stem seals can cause it...possibly the timing to??

Det will have done the pitting on the ex valves. Probably not advisable to reuse them but i have got away with it in the past.

u can get them reground with the seats if u like but other members might have decent spares lying around.make sure there's no pitting on the valve-rocker face!

When my head got rebuilt a pair of years back, Renault did me a decent price on them. Cant remember how much, but it wasn't as heavy at all as I'd feared.

£86 for new valves. i may aswell order a set unless any one has some they want to sell me.

As long as the stems aren't worn, just get them refaced, be a lot less than £86.
