I checked my valves last night and they all appear to be a bit tight, but the feeler gauge I have doesn't have nice round numbers on it and the increments seem kind of large to me. On the intake side I could fit the 0.076mm but not the 0.102mm which is the next size up. Spec is 0.10mm-0.15mm. On the exhaust side I could fit the 0.176mm but not the 0.203mm which is the next size up. Spec is 0.20mm-0.25mm. Do most feeler gauges have smaller increments between them so you can get a more accurate reading or is this normal and people just split the difference between the one that fit and the one that didn't? Also, while I have you attention, I read that you are supposed to use assembly lube when putting the cams etc. back in. What exactly is assembly lube? Thanks in advance for the help.
