Secondary intake runners gunk buildup issue
 

After a month of sitting in storage i decided 2 go and take my intake manifold off 2 fix some wiring issues and for my surprise i had this thick gunky oil fuel mix on my secondary intake runners,the second that i removed the uim i saw that my lower intake flange was covered in what looks like oil gas gunk mixture and a second look 2 my upper intake revealed that some of that junk was going up the upper intake manifold all the way up 2 the throttle body....after cranking a little this stuff got on my spark plugs 2.Again this is a thick oil fuel exhaust smelly gunk!i Looked at my intercooler pipping for signs off oil and there is non but the turbo is leaking a little oil dripping down the intake wheel.Looked at my catch tank and is empty and pcv sistem seems 2 be fine.My secondary runners were covered on this junk but my primaries are still clean and smooth and again smells like fuel oil and exhaust all together,another thing is that my oil level went up almost a full quart!I know for a fact that is not fuel leaking cause injectors have 50 miles or so(brand new RCs)so any ideas of what is causing this issue?Blown turbo seals,bad oil control rings,blow by?
Here are some specs on the motor.
Late model S5 turbo block
Half Bridge(huge bridge notched housing)
720cc 1600cc injector combo
Turbonetics 72mm with long runner manifold
MT LT16
