Tapping on top would be a lifter. Mine does for a min. until warm then goes away. With a 172,000 mi. doesn't bother me til I get a new engine. Where's the knock coming from?

You might have a stuck lifter. There is a TSB out there about it, # 932414 but I can't locate a copy online right now, I will look again tonight

Can you grab a video of it?

What weight oil are you running? When did this start, has the car been sitting for an extended period of time? Has the car run low on oil at any time?
