this is not for my mondy but my brother in law has just bought a rover 200 today,1.4 16v petrol v reg,any how came to me so i could have a squiz at it but on inspection i noticed oil in the coolent and a very oily cap,(he's got 1 month gaurentee) and i said that the headgasket might be on it's way out or maybe it has gone before and coolent has not been flushed properly.lot's of oil in bottom of air filter box but filter has been changed by the garage and so has the oil,what do you think guy's could it be somthing else?
