What are common issues with a 2008 Subaru Outback 2.5i?

I’ve got a '08 Subaru Outback 2.5i here in Cali, and head gaskets are a real pain. Had to replace it twice already. Engine oil leaks too. Guess they weren’t too great with the quality check!

I’ve had issues with the 2008 Subaru Outback 2.5i in Chicago—whining belt and oil leaks mostly. Had to replace the A/C compressor too. Anyone managed to fix theirs without spending a fortune? Need some good mechanic tips!
