All other service was done at Lonestar BMW in Austin, this is my first time taking over.
Do dealers set them tight to keep the noise level down?
Does the spec I state above (.075mm/.15mm) so tight that damage might have occurred?
Notwithstanding the single value .15mm and .30mm spec, I assume there is actually a range. What is that range?
SOME deallers use a go-no go-guage. So sometimes they will be a tiny bit tight. I know of no dealer that would intentionally set them tight. Tight is bad. There really is no "range" like on the Camhead. They are either right, or they are not.
