Thanks for the reply. It was in a garage the week before Christmas and got that cooling fan replaced due to leaking ( It looks like the mechanic never washed around the oil cooler) could be the old water but the water level does not drop now and the oil level does topping up a litre a week. It beās driven around a 100 miles a week. It seems to be very wet with oil under the throttle body and inside of it could the oil be puddling inside the throttle body and then leaks through and the old water that was there just made it look worse? ThanksAs above, it looks like water - which is possible due to condensation inside the intercooler - are you doing only short journeys?
Oil is normal and intended - the old style turbos have a seal on the end of the shaft to prevent any oil egress, the trouble is that carbon builds up against the seal and progressively prevents lubrication. More modern turbos allow some 'weepage' so that the whole turbo spindle remains lubricated.
I would say 1 litre of oil per 100 miles is excessive and then some.Thanks for the reply.
