I just noticed what seams a significant oil leak on the left side head gasket in my 2006 Forester. I maintained the car regularly so I was surprised (and disappointed) to find the engine all covered in oil.... Anybody knows if there has been a recall on this item? Also if you had a similar problem I would appreciate any info on how you resolved it with Subaru. The milage on the vehicle is 97000 km. Thanks in advance.
