I have some oil residue on the air filter itself indicating a malfunction. CDR valves normally serve this function by ensuring oil doesn't make it into the air intake, causing problems down the line. I think we have one -- synonymous with the pcv valves on gas engines. If not the CDR, what part might be malfunctioning? Also Chris check your inbox... I sent you a PM.
