You probably over tightened the valve eccentric nuts and changed the gap.
Always check again after tightening. Use one size up to check gap after tightening. A .012 should not fit, and .008 or .009 should be way loose. Turn the crank over and recheck each valve.

First time I did a valve adjustment some of the exhaust valves ended up being tighter after I ran it, i think when I remeasured they were .008 or so. Ran smooth as butter after i adjusted it to spec. Go get the BavAuto tool and call it a day.

Its spring loaded so it helps set the correct tension so you don't over tighten and change the gap. The tool bends in the middle and has two angled sides.

Sent from my iPhone using TapatalkOriginally posted by digger View Postif you use something relatively stiff when you turn the eccentric you can generate enough force to move the valve slightly open because of the mechanical advantage of it. This affects the true clearance as when you take the feeler out the valve moves back a tiny bit and the clearance you get is less than you wanted. The tool stops you putting too much force into the eccentric ,as the tool essentially collapses limiting the force.Last edited by Idrisu; 04-12-2017, 08:56 AM.
