Here is another theory.


I have been reading BMW actually replaces the cylinder heads (if under warranty, of course) to fix this problem. So, I am guessing the problem is with the heads which lead me to think that the tiny oil ports that go to the lifters etc. may be blocked or not functioning well? The oil pressure will still look good and you can replace the lifters to the new ones but when there is no enough oil supply, the ticking will continue..


If that is the case, how can we clean those ports without pulling the engine apart physically?


Any ideas?


Thanks,


Ozzie
