Thanks grumpy .After lapping I am wanting to check on valve clearance but only have metric feeler gauges,I went shopping to get an imperial set but came home empty handed(joy of living in the middle of nowhere) would someone have some metric figures that I could work too or should I head to the big smoke to get a set.The engine is a 9T502 (9 series?) intake should be .005 to .007 exhaust .007 to .009.I found an online conversion calculator but it doesnt really match up with metric feeler gauge markings.I dont really want to go ajusting valve clearance on a hunch and ruin the valve.
