You two ^^^ :haha:
It could well be the oil seals, although in fairness, if its a brand new turbo done 0 miles and no heat cycles, the seals should be fairly soft not corroded. But as said take the downpipe off, give inside a wipe with your finger, any oil is bad news.
Also remove the air filter from the compressor housing, a slight thin film of oil here is OK, anymore than that and it's not good.
Get the seals done mate as it's one less thing to worry about!
Hope it all works out for you lad.
