Hello fellow owners/enthusiasts.
Yesterday I conducted the 12k mile service. When checking valve clearance I noted that all valves loosened since the 6k mile service, though some appeared to loosen quite a bit. Below you will find the comparison.
Although only two are out of spec on the loose side I will adjust all, with larger shims, to bring more toward center of range.
This being my first BMW I am looking for input on whether this appears normal. How much impact would engine temp have on these measurements? I ask because the 6k was conducted in a closed garage where the 12k was conducted in a car port where there was a steady breeze and cooler temp ~10 degrees Fahrenheit, cooler.
Thanks in advance.
