Hi all,

So I've taken apart the cylinder head and I'm going to grind in the
valves. I'm wondering how best to clean up the deposits around the
valve seats. Can I really use a small wire brush in an electric drill,
or will that munch through the soft allow in short order? I understand
that the valve seats themselves are hardened, but what about the
surrounding metal? Am I better off going easy with a plastic scraper?

Thanks

Luke

Only if you're really cack handed for a really long time.

That will take a really long time.

if you leave it to soak in petrol (or even water) for a while it will clean
off with little effort. an engineering shop would stick it in the hot
washer overnight for a small fee, that gets 99 per cent of it off.

if you realy want to brush it off then get a brass brush which should do
minimum damage.

Diesel works as well, plus it's a little more difficult to set on fire
