[QUOTE="HawkWing, post: 900251, member: 21120"] Doing my first valve check/adjust at 30000. All measurements check out within spec, except two exhausts: cyl. 1-1 @ .0102" (the 2/10000 is my best guess, based on tight fit of a .010" feeler gauge); and cyl. 4-1 @ .0100 (again, based on feel). The spec max for exhaust valves is .098" I'm debating whether to risk complications (skipped sprocket teeth, etc) for making such a small and (to me) inconsequential adjustment of a VERY slightly out-of-spec valve. Any guidance or advice would be greatly appreciated. What would you do-- increase shim thickness .05mm, or leave it alone for another 15-20 thousand miles and re-check? Perhaps give it Fred's Seafoam treatment and see if that brings it into compliance (by blowing out any carbon buildup)?
