CCV/PCV Not the Problem?
08 Z4 3.0si black cover. Replacing the diaphragm in the valve cover since I've been getting all sorts of issues, including tons of oil in the intake and lower DISA and running rich codes. Now I'm not sure if it is the CCV/PCV. I removed the cover on the diaphragm to do the "hack" with out replacing the valve cover but the diaphragm is only a little oily but otherwise in great shape, no tears or holes. Maybe this isn't my issue?
I did have too much crankcase pressure as well, difficult to remove oil cap, an oil leak at the valvetronic motor gasket when doing AutoX. Also looks like it went through the intake gaskets. DISA motors look fine, no broken flaps but covered in oil. I do smell fuel in the intake oil. Any other possible culprits? Thanks for any help! |
