I'm at 14,800 miles, doing the first valve adjustment on my 2008. I was hoping everything would be fine, but I've checked the front cylinder and they could all use adjusting. Intakes are at 0.004 and 0.005, on the tightest side of the 0.004-0.008 spec. Exhausts are out of spec at 0.006, spec being 0.008-0.012. Should I adjust to the loosest end of the spec, since mine are tight and will probably continue to get tight from what I've read?
