now then lads & ladies my 97mk3 VR6 started to get lumpy on tick over. when i checked the plugs, the spark plug in pot 6 had oil on it. all the others are fine. now i have replaced the plug. the car pulls really well, the tick over is fine and there is no sign of smoke from the back. the mileage is 88k and i had it serviced at 82k. am i worrying for nothing or have i got a big problem brewing! cheers
