This new design is indeed new and addresses the problem. My ticking was immediatly gone with no problems into the second week. Trust me at 8k a pop bmw is NOT going to make this mistake twice. This is going to be the sturdiest, non-ticking engine they ever make. I am sure this head was designed VERY carefully and like I commented they would not do all this work and pay 8k for each person if they did not know darn well it hurt the engine.
My dealers as well had a procedure to bleed twice and then submit puma-that is the general concensus.
As I also stated this head was clearly designed with better oil flow in general as the performance is much improved. The rev's get up there way faster and the engine is much stronger. I think they wanted to reward all of us who had to deal with this with a few extra horsepower in this head design as it is noticablly faster.
