- replaced the diaphragm in the built-in CCV
- glued the diaphragm cap back together after the tabs all inevitably broke during removal
- replaced the dipstick tube with the M56 tube (you can also cap off your OE tube)
- ripped out all of the original CCV tubing/canister/etc
- capped off one inlet the air distribution piece and ran a hose to from the valve cover to the other inlet
- did vanos seals and spark plugs before reassembling with the new M56 specific valve cover gasket, spark plug gaskets, and bolt gaskets
I've had no issues with it since install and would recommend the swap to anyone. Let me know if you have any questions!
