This is frankly fascinating.
I've toyed with the idea of a catch can, but have heard conflicting reports about their true worthiness in combating oil vapor deposits into the intake system.
Now I'm hearing about the sub-par stock PCV valve (leaks under boost) and the replacement....

Not to mention the outstanding pdf how-to done on the intake valve cleaning.

This makes me want to open the engine back up again and look at the valves.

Any opinions on here about the BMW oem pcv valve?
