Oil in water help please.

[Gates]

Evening all I've been having a few problems with my 2.0tdi lately, a few months ago my coolant light came on as I'd lost nearly all my coolant so I topped it up and checked it later on in the day and noticed my header tank had a few cm's of oil floating on top of the water. So I dropped it into my vag specialist who changed my oil cooler, filter and flushed etc. And all seemed fine, until a few weeks later I noticed a bit more oil in there again, now the car drives spot on with no loss of power, overheating or any other symptoms at all. I do about 400 miles a week in the car commuting to Heathrow and just change and wash out the header tank every couple of weeks.

Can anyone help as to what the problem may be before I take it back to the garage so I have an idea what to ask him to fix, I haven't had chance to take it to him to get advise as of yet as I'm away 5 days a week and we are trying to sort out moving house.

Any my help would be great as I'm really starting to wish I'd never bought this alcar after having to change the bottom end last year from oil pump failure.

Thanks everyone

Can anyone shed any light on this please??

My thoughts are that you have a head gasket failing.

+1 for possible head gasket failure, but worth looking at egr cooler If you have one....

It's not a HG failure.

You will struggle to get all the oil out of the system, so it will keep coming back into the header as it finds it was through the block, pipework and radiator. Best you can do is to keep removing the header tank every so often and clean it out.

Mine been like it for years since the oil cooler broke and got replaced. My coolant is a light brown colour, its had a lot of flush through's at the dealers but it still comes back light brown.

I have just learnt to live with it.

That's what I was hoping guys, thanks. Although it's still looks like quite a bit of oil rather than just brown coloured coolant. I'm going to get some coolant flush friday when I get paid and empty the header tank and fill up with flusher and run for a couple of days the just empty header again, then drop the bottom hose off the rad and flush through with water and add coolant. I'll keep you posted on how I get on
