When the lifter sits for too long a period without being run, the oil will drain out of it. This allows the lifter to completely collapse until the lifter can be filled again. During collapse, both sides (top and bottom) impact each other and thus creates the noise you are talking about.

What happens if a hydraulic lifter is broken?

What happens if you break a hydraulic lift cylinder?
If you have a broken hydraulic lift cylinder, it’s not uncommon for the pushrods to become bent or broken too. If this happens, you won’t just have an exhaust valve or intake valve that isn’t working optimally – you’ll have one that isn’t working at all.
What is the function of a hydraulic lifter?
Hydraulic Lifter Function. Your vehicle’s hydraulic lifters’ only job is to transfer the force from the camshaft lobe to the valves. For the valves to remain closed, they need a little bit of play between the camshaft and the valve because metal moves when it is warm. This is the job of the hydraulic lifter to control this play.
Why are hydraulic lifters better than mechanical lifters?
Hydraulic lifters have an advantage over mechanical lifters because they sit directly against the camshaft lobes, where traditional lifters have to leave a small space for expansion when they heat up. While the exact way the lifter operates is slightly different, they serve the same function.
Why does my car have a pushrod?
