Problem description The car has developed an engine fault; there is a knocking sound from one of the cylinders and I suspect either a piston issue. The problem occurred whilst accelerating on the Motorway and the symptoms were a loss of power followed by a tapping sound, which remains. I drove the car home following the issue and it doesn't appear to use any oil. The oil on the dipstick appears clean i.e. doesn't contain metallic particles or swarf. The water temperature has remained stable and the motor did not overheat at any time. It does not use any water and the oil is not contaminated. The car will probably get you home but this is to be attempted at the buyers risk. I'm sure if will make a nice car for someone who has time to rectify the problem. Buyer to collect from Lincolnshire (close to Lincoln), cash on collection.
