Leak became more prevalent.. Dripping from back left read top top motor
where the two hoses (large Yellow Arrow) loop under and connect under head
(small Yellow Arrow). Plan to pressure wash and get better look.. any clues
to what is connection there would be appreciated. I borrowed this picture from another post.. But engine is same 2.9 24 valve 6. MY car is 98 S90

Tks

 

Sounds like a rear main seal. Make sure you are not building up crank case pressure.

 

I had a similiar issue with my S90, I replaced both cam shaft seals and sealed the cam shaft position sensor. This is not a easy job and if your not mechanically inclined leave it to the pro's. Ensure your PCV system is operating first. Good Luck
