One thing that almost got me on my ccv kit (with hoses) is that one of the hoses had an oring that didn't fit correctly into the grove. So instead of compressing into the grove upon insertion, it wanted to shear off. So I ended up using the old oring for this one particular spot and all was good. Just figured I'd share just in case it might help...Gonna be the death of me
I plugged the hole that remains after removing the dipstick, to prevent particles from entering the oil pan. I took the connectors out of the old crispy plastic hoses and replaced the hoses with industrial grade hoses. I also replaced the oil separator while I was there. My 528i wagon is now running smooth. I still have a minimal vacuum leak that whistles after 1800 RPM. It is coming from one of the vacuum plugs at the rear left corner of the intake manifold. I have to find that 7 mm and the adjacent 3 mm vacuum plug to finish the job, but my nearest dealer is 1 hour drive and they don't stock much of anything, nor do they take phone or internet orders. I'll have to get creative. I wander if anyone has found aftermarket replacements for those plugsI'm going to attempt this job, but do I need to drain the oil first? I didn't see anything about that. Thanks!

As someone who just went through this process just recently I must say you have done outstanding job!This is the journey I would not take again. Major PITA. Oil separator is a "tricky sucker" like somebody commented. But I hope the pictures of every step of the way will make this diy a little easier for somebody else. I followed these 2 wonderful DIYs that contain everything you need to know:
