[QUOTE="RossKean, post: 1375300, member: 19880"] So what do you do after five valve checks?? The poll runs out of options. [IMG]https://www.fjrforum.com/forum//public/style_emoticons/default/smile.png[/IMG] I just did my 5th check after 173,000 miles or so. It was close to 50,000 miles since my last check. On the previous check, I made a number of adjustments for the first time. This time, one intake on #4 was just below spec and the other on #4 was right at minimum spec. I sanded these shims to bring them back to where they needed to be. I also confirmed (to no surprise) that previously sanded shims wear the same (i.e. not at all) compared to factory shims. I was a little surprised to see the #4 shims off a bit while the others were all good. I have never had to adjust any exhaust valves. [/QUOTE]
