2005 td6 head troubles

morning folks ,
while out checking a few bits on RR I noticed there was quiet an amount of black oil in the expansion tank.
oil level has dropped no signs of water in the oil or on oil cap,
is there anywhere else oil could get into the cooling system a part from head gasket failure on the m57?
roughly how many hours are in doing the head, rough cost?

You haven't got your car for sale have you? scammers are pouring a small ammount of used oil into the header tank when the seller is distracted then saying the head gasket has gone and making a cheeky bid.

sadly not up for sale , just having a poke around and I noticed it,black oil.
never heated past half way.
find it strange tho running 100% .

EGR cooler is known to leak but coolant not oil.

They have and oil to water cooler it may be split

wot @brianp38dse said .

Oil cooler would be the most sensible place to look.

cheers guys, after a lot of fiddling to get the oil cooler out and a few choice words looks like the cooler gave up so now the fun job of flushing out the cooling system

Well well well, just seen some one over on fullfat with same problem so if thats you @returned go have a look at my answer.
