I wouldn't just leave your ticking valve lifters alone.....there's no oil in there. That's why they tick. No oil=excessive wear and increased heat.....2 things you don't want in your engine.

There's a TSB out for the lifter tick.....I had my engine head replaced. The new head incorporates a check valve to maintain oil pressure when the engine is off.

Haven't heard a tick since.
