Hi everyone! I’m new to this forum, but on my 2009 forester 2.5i with 100,000 miles i noticed an oil leak under the right and left head gasket. i know these cars are notorious for external head gasket leaks around this mileage, and was just wondering what y’all thought? should i be concerned and replace the gaskets soon? the top picture is under the left side gasket and the bottom is under the right!
