Replacing the Crankcase Ventilation Valve Help Needed

Guys, my mechanic stated my Crankcase Ventilation valve is bad and needs replacement. I took my 540 in when the Service Engine Soon light came on. Mechanic stated the were getting "Lean on Bank 1 and Bank 2. Has anyone ever replaced this valve, which is on the back of the intake manifold?


Does it makes sense that this valve, which is part of the Oil Air Seporator, would cause a Lean condition on both banks? Anyone ever had this happen? I have attached a picture of the manifod system. The valve that needs to be replaced is item #2 in the diagram.

If anyone has replaced this as a DIY, please let me know your steps.

Dave

Sounds like the valve is leaking and allowing excess air into the manifold, and therefore making both banks run lean. There is a diy for the replacement here:

Although it is for a 7 series I would guess the procedure is pretty much identical for the 5

Thanks

Did the removal and install in about 1.5 hours this past weekend. Eveything was successful.

Replaced mine on 01' 540i at 95k miles and it took about 2hrs. Damn near stripped the bottom most torx screw even with a new bit. Grabbed another bit from the toolbox, said a prayer and luckily the almost stripped torx screw broke loose. Replaced all torx screws with stainless hex nuts like the DIY writeup suggested. One more thing; the clip shown on the DIY for on step #2 did not exist on the 01' 540i and the tube just pops on and off (be careful not to pull the tube off the other end). Best of luck!

These may be useful ...
- CCV FAILS: crankcase ventilation valve diaphragm tears, freezes (1), &/or clogs (1), necessitating CCV replacement (M54,M54,M54) (M52,M52) (M52TU) (M62,M62) ('99 528i) ('98 528i); raising pressures, often causing the OFH oil filter housing to leak (1) (2) (3) (4); frequently blowing the VCG valve cover gasket (1); and sometimes the head gasket (1) (2); often causing vacuum leaks (1) (2) (3)
