But last weekend I drove around 200 miles and after that trip, the ticking noise is gone. I cannot hear from Monday, Tuesday and Wednesday.
I'm pretty sure that is either hydraulic value lifter (HVA) or cylinder head issue, but the thing is I cannot produce now.
Not sure how to reproduce again, if the sound does not produce again, I cannot ask dealer to replace the part for me.
Any suggestion??

What I've noticed is this: I have 2 e90's. One get's driven about 10 miles a day IF that. The other get's around 40. The one that drives more hasn't ticked a tick in it's life, but the one that doesn't go anywhere had the head replaced. I'm thinking that there could be a correlation with the car not getting fully warmed up/not being driven enough to prevent the ticking from happening and that's why it happened (most of the time) when my car was cold.
