I have a 2004 1.6 petrol Zafira when driving to the supermarket I noticed a drop in power when I stopped the car was smelling quite bad so I lifted the bonnet to find oil all over the engine, I drove home (no choice) and it had reduced power again. Could it be crankcase pressure forcing oil up the dipstick or something more sinister?
Its had oil and filter change earlier this year.
