Hello

if you've got a top-end rattle or regular ticking that increases in tempo with increasing rpm then yes I'd agree it could be a sticking valve lifter, as these use a small hydraulic piston to take up the valve clearances and what can happen is the small oil ways that feed the piston chamber can get clogged up

So the 1st course of action is to try an oil flush treatment complete with a new filter and fresh oil
