I’m looking into buying a subaru but am worried about the head gasket issues. The one in particular is a 2000 with the 2.5 DOHC NA engine. It had the timing belt done at 80,000 so and currently has 135,000 so I should have a couple of years left on that timing belt but my other main concern is the head gasket issues. Do they all get them, is it really hard to do yourself. How expensive to get done etc. I work part time while in college so I don’t have a huge budget for repairs is it bad enough to take it out of the running?
