I have just found oil in my radiator and expansion tank. Any thoughts/suggestions as to what this could be?
We would suggest that the cylinder head gasket has failed. Does the engine start okay and run okay with no misfire? You may be best at this stage to have a compression test carried out as this will confirm the head gasket situation.
