Yup--none were loose, all were tighter than specs, and a few exhaust valves had ZERO to negative tolerance (tight!). I felt pretty good about catching that. My truck doesn't have that slight cold miss that it used to have. Runs very smooth now. Oh, and as a bonus, my check engine code 2279 when away once I did the valve adjustment.
I also changed my tensioner and was surprised at how much quieter my car became! It had been rumbling for a while and was getting worse each week. So you know, I tried pulling the pulleys off, cleaning the bearings, and repacking them, but it only stayed quiet for 20 mins or so. Those bearings are under constant load, so even a slightly worn bearing can make noise.
FYI, mine made noise when the AC turned on, then quieted down a lot when the AC turned off. Many would suspect the AC clutch, but my trusty stethoscope pointed to the tensioner pulleys. Best $175 on a part I've spent in a while. I know I could have gone the cheaper route by replacing just the pulleys (O'Reilly's $70 for both pulleys), but with my luck, the tensioner would go next
I was ready to relax and enjoy my Sunday today, when my wife yelled from the garage that the washing machine was beeping. Code F11 on my Kenmore H3t. Oh well, the fixing continues--removed the circuit board and found cracked solder joints under the relays. Resoldered 'em all and BAM, it's working again. Added some sound-dampening material to the parts and the cpu case and it's washing clothes vibration-free
I guess it's been a pretty productive weekend after all!
