Turbo Oil Leak

My 200TDi has been leaking oil for a while now, it drips off the front of the bellhousing, the sump and exhaust downpipe. On further inspection I traced the oil path upwards and it seems to be coming from the mid-section of the turbo. Everything below the turbo is covered in oil, it runs down the side of the engine and the exhaust. It only drips oil after it's been driven, none appears if it is left for a few days.

What should I do about this? I assume the oil comes from the turbo oil feed and/or return, what would cause them to leak? I've taken a few pics of the area.



Also, on another note, I noticed earlier some build-up in the header tank, don't think it was there last time I looked unless the water has dropped a bit. It's brown but not gunge, it's hard and can be scraped off slightly with a fingernail. Nothing in the oil, clean exhaust when warm. Anything to worry about? I bloody hope not.

OK, so doing some further evening research has led me to thinking that the two copper sealing washers at the oil feed banjo could be the culprit, or a good place to start at least.

Does anyone know the size of these washers so I can get some before I take it apart?

More likey that yer turbo is on the way out. You'll know when it blows and so will the cars behind

Ah christ I hope not. I already need a new gearbox...

no you do need new washers or maybe pipe if cracked were it joins banjo ,you may need a head gasket soon

Check your intercooler hoses to see how oily they are.... It only takes a couple of minutes to piop them off.

Thanks James, don't suppose you know the size of the washers? HGF is all I need

Intercooler hoses do have a bit of oil in them if I remember from replacing a split hose. Could that not be the cyclone breather as there is some oil also present in intake hose from air filter?

I mean like very oily (pressure side)... But I would go with James' suggestions, he's normally on the money.

Thanks for your help, I think I've tracked down the washers - ERR896. Will replace them as soon as I can, hope that sorts it.

Will keep an eye on coolant.
