Oil In Water

[CATT]

Went to check water today on T reg tdi and there is an inch of oil on top of the water in the expansion tank, the car is still running ok without over heating at the moment. Could this be the oil cooler coroded inside or more likely head gasket gone?, i still have full power too. Can i do a check to see if its the oil cooler first instead of scrapping it, thanks

PS there is no creamy gunk on dip stick so looks like its oil in water and not water in oil...

Is the car manual or auto as it could be fluid from transmission if an auto

I go with oil cooler,had the same on my mk1

Also when u change it the cooling system will need a damn good flushing out as the oil destroyed all the water hoses on mine, luckily its summer so u wont be loosing antifreeze when u drop the water

I used washing detergent in mine!!liquid of course,stuck in run for a day dropped it out and flushed. Repeated a couple of times and all was well

Chris yes it is a manual car , and thanks for replys, i am going to pull the pipes off on wed and see if the oil comes out of the oil cooler whilst it is running, hopefully it will be that... and i will see how much i can get one on ebay for...
