Where is the oil leaking from??

Hi, I've got a tiny oil leak on my xc90 T6. Volvo dealer tells me its crank oil seal area but they wanted to charge me loads a money to clean off that part so they can investigate. I was wondering if there are any oil pipes or connections down there that could leak. all the pulleys and aux belt are bone dry which is strange because I would have thought if it was the crankshaft oil seal wouldn't that run down the crankshaft pulley and then spray oil everywhere. the amount of oil loss is so small it doesn't leave any drops on the drive and the level on the dipstick never moves. its more annoying than serious but still needs sorting. Any advice would be welcomed

If it is front crank oil seal then just wait until cambelt is due and have it done at same time as they will have to take belt off to do it,

The oil pump housing is located behind that seal and there is a paper seal between pump and block along with a rubber circular seal then a normal oil seal between crank output and oil pump housing,

Thanks Rooster.. cambelt was done at 82k so and when it comes up ill be doing it myself. not a difficult job just lots to remove and then refit. Its on 105k so may be a while before its due. Project for the spring I think. I'll buy the locking kit as and when im ready.
