Take the cabin filter housing off, and use the extra space you now have to replace the vacuum line that runs from your SAP around the back of the head. For that matter, if you're gonna work on potential vacuum leaks, replace the intake elbow, it'll crack on you sooner or later. And get a new o-ring for your DISA valve.

intake piece? what exactly do you mean? the intake manifold? what o-rings specifically?

also, I havent heard of the SAP before, guess I'll research that around lunch today lol.

I had heard you need to replace the DISA valve, do I just need an o-ring or the whole valve?

Also, when I was looking up the CCV on the bmw parts search it came up with two for my engine and I have no idea how to tell which is the correct one for me.
