Began smelling the sweet smell of coolant burning as temps have dropped. Traced back to LH head, rear side. Dripping about 1 drop/min after shutting car down (until everything cools and the head-to-crankcase clearances join back up). This followed after a recent coolant servicing. Application of Subaru Coolant Conditioner as instructed by the WRP-99 seems to have abated the leak for the time being. Will be replacing head gaskets as soon as funds allow, as 8 yrs/100k miles was aptly chosen and we are now beyond that 8 yr limit!
