anyone seen oil in here before?

[bimfest]

Hey guys i have taken out my front cv axle because i am doing a oil pan gasket because its leaking somewhere (already done ofhg and valve cover) and in the process of taking it out i noticed the inner cv boot was dripping some brown oil, definetly smells and looks like brown engine oil.
But here is the interesting thing, when i take the whole axle out i have brand new oil(golden) in the bearing that sits in the bracket that holds the axle and is bolted to the side of the sump. i have attached a picture of it. Also attached a picture of the brown oily substance coming out of the inner boot...i suspect it may be oil + grease mixed together somehow...

I have 2 theories....1 being my oil pan gasket has leaked and gotten into the driveshaft seal and made its way through to the boot...although unlikely since the shaft itself has no evidence of oil, neither has the tunnel through the oil sump all perfectly clean.
2nd the oil that is in the bearing has slowly made its way to the boot overtime and mixed with grease and when i moved it around the boot has come abit loose and this is what i have seen come out...
