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
