I checked each valve clearance after adjusting it and tightening the nuts down. But I did not run through each valve again before putting the cover back on. Let me run my predure by you guys to see if I'm doing it right.

First I get the cam lobe pointing 180 degrees away from the rocker pad. If the valve needs adjusting, I break the bond between the two nuts by applying CCW torque to the cap (top) nut and CW torque to the lock (bottom) nut. That breaks them apart, so they can be turned independently, without turning the whole valve. Assuming the clearance is too tight, I then tighten down the lock nut so that I can bring the cap nut down too, increasing the clearance. When I get the right clearance, I hold the cap nut in place and bring the lock nut up to it. I try my best to not turn the cap nut while applying as much CCW torque as I can to the lock nut. After getting them tight, I check the clearance to make sure it hasn't changed. If it did, I repeat the whole process.

This is just what I did today, and now I get these wierdo noises! Guess I need to recheck the clearances tomorrow...
