Do yourself and your X a HUGE favor, and replace the CCV and all its hoses while you have the oil filter housing off. You can thank me later...

Replace your oil filter cap. At your mileage, it's time.

Replace the o-rings on each port of the intake piece.

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.

That should keep you busy for a day or so. And your X will thank you when you're done!
