So I can add Valve Clearance Adjuments as another notch in my DIY Success Stories Belt. :eclipsee_gold_cup: And as maleko89 and one2dmax forcasted, I found my clearances either w/in tolerance or too tight
So my question: Even though, Sean provided an explanation, my naivety is preventing me from picturing the disappearing clearances. :ummm: Could anybody elaborate a little more on this manifestation? :worthy: Thanks all.
In the bikes I have done, intakes tighten a little bit and the exhaust valves tighten even more. I have yet to see valve adjustment too loose.
...
Mark is correct. Usually they all tighten up. I read somewhere that I think Damon F. said one tightened and one loosened. BUT, if you think about how the cams are oriented compared to the valves. As they wear and slowly shift deeper into the heads the clearance on the cams is reduced so thinner shims are needed.
I would not consider it normal for the clearance to increase (about the only way this would happen is if the base of the cam was getting worn off). If this did indeed happen the you would have either a sticking bucket which wasn't rotating properly (the buckets slowly rotate as the engine is running) or a lack of lubrication (which would eat the lobe off first).
