hi guys,

my engine has a slight tap which gets louder and faster with revs. we have just replaced 2 bent valves, is it possible the oil hole on the lobe isn't lining up with the head resulting in it not getting enough oil and therefore causing the tap?

Possibly, but why would it randomly stick?

you may have a stuck lifter or two after the bent valves? its possible that when the valves got bent the lifters where forced right in on theses valves and are now stuck. take the cam cover off and have a look to see if any lifters are lower, softer than the rest or not touching the cam as you turn engine over by hand.
