Valve Clearances tightening

[LakeWylieJoe_imp]

I might be more-anal-than-average, but it's nearly as easy to adjust all 16 valves as it is just 1. Why not put them all in the center of the spec range? If one is right at the limit, it could be out of spec by the time you get home.

If you paid for a brake job and the pads were right at their service limit, would the shop send you home that way? it's not a perfect analogy but you see where I'm coming from.
