Hi I have a au 4litre in a xc,, it has been running rough, I've taken the throttle body off and found milky oil on the back of the butterfly,, I checked the oil its not milky though,, any ideas would be great cheers

could be just condensation, how often is it driven?
also unscrew the oil filler cap and see if its milky in the cap?

Hi mate everyday,, checked under the cap ,on dip stick its no milky,, I thought I was in first but was in third, stalled it and that's when it started
