Howsit

Your CCV or otherwise know as PCV (pressure control valve) is under the intake manifold, its a mission to replace and you will have to take out the intake manifold. Its probably harder to change on a M3 because of the individual throttles. Check on e46fanatics.com for a diy.

Read nicely, he said M43, which is the 4 cyl, not the M

On the M43 it is easy as pie, its a couple of covers to take off and some bolts need to be loosened, should take you about 30 minutes to complete. I needed to remove mine the other day to inspect the DISA valve.

If you are really stuck give me shout then maybe I can help with the install.
