This sounds possible , ill have a look at the weekend cheers

	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?
