Hi guys,

I've got quite a lot of carbon build up on my exhaust valves and I've tried to remove it using a wire wheel but it hardly touches it.

Have you guys got any other methods of removing or dissolving carbon ?

Thanks.

Put valves in a drill and use very fine emery paper and wear a mask or use some egr / turbo cleaner .

Gently by hand with an old hacksaw blade

I bought a new set - quicker & easier by miles.....

Cheers lads,

I put them in a drill and used some sandpaper.

Got the boring job of lapping them in tomorrow night.

Thanks.

if there is a lot of valve wear and the valves are clearly old I'd recommend you just buy new ones as they'll seat so much better plus most valves are quite cheap really. I use to spend hours doing this trying to reuse as much as possible but these days just buy new valves and get a machine shop to do the initial refacing of the seats, it's like £50 plus they check the guides at the same time and then I just do the final lapping them in. The results are so much better.
