Valve clearances, close enough?

JoelB · 10. Januar 2013

I did my valve clearances today. I have a couple of dozen shims which I thought would be enough but the best I could manage was: Intake.. 0.16, 0.2, 0.165, 0.165 Exhaust.. 0.25, 0.26, 0.27, 0.25

Particularly with respect to number two intake, is this close enough?

This it the wrong question. The corrct question ist, is 1, 3 and 4 wide enough? 0,2 mm is perfect, 0,16 is in the tolerance band, but not for a long time. 0,25 in exaust ist also very very close, better is 0,30 mm. With 0,25 mm you have to do this work in a few 1000 km again.

Fully agreed with Henning, you want the clearances to be at the higher end of the allowance. With wear the clearance only becomes less.
