Hello all, 2006 S60 2.5T, and it looks like there is a oil/fluid leak around the latch that holds the timing belt cover in place. Cam seal on that side?

 

could be the cam seal or the VVT gear/solenoid. Time to pop the covers off and take a look. You don't want to have a wet timing belt. Also, if you find you have leaky cam seals, test for a clogged PCV system. If the crank pressure can't vent via the PCV system, it can push the oil (or seals) out

 

PCV System was replaced the beginning of March, so I suppose this could be some residual issue left over from before.
