Hi Guys,
Just removed my PCV from the rear of my L322 4.4 V8...I didn't have any issues but it's a known area on these vehicles that's often overlooked.
It looks like mine was the original BMW part, I found mayonnaise in one of the breather pipes and oil sludge in the other one, the oil separator is bad too as it's almost blocked. I thought I'd mention this so that you might want to take a look at yours, it's a tricky job to change the PCV, I don't recommend that you just change the diaphragm as in some videos I've seen, it's 5x torx 30 and 2x 10mm bolts plus a couple of hose clips if you want to remove the oil separator. I recommend you check this and the pipe below the oil separator just to see if it's blocked up. A way to check the PCV is to remove the oil cap when the engine is running, if it's hard to remove due to suction then your PCV is probably bad, mine had done 137k miles and looks original hence the reason for changing it...just thought I'd share..
