I've been doing valve clearance today. It's been a while, and I could hear a slight tick.
I set them at 0.018" warm. Thinking it might give a little more overlap that wouldn't hurt. There were still a couple that were making a little noise, so tweaked then a bit more. Thinking it might be wear on the rocker tips.
Hopefully that's all good, and any comments welcome.
I was wondering if it is normal for some rockers to be off centre from the valves quite a bit?
Grateful for any feed on the subject.
