I’m pretty sure my head gaskets are starting to fail again on my 08 Outback 2.5i. The first time was around 99,000 miles, currently have 168,000. I was checking out parts on Rockauto.com, and wondered about the quality of head gasket sets. I know that Felpro are supposed to be good, but that’s what I used the last time. Anyone had experience with Enginetech brand? The set is less than half the price of Felpro. They also have headbolts, which I think I may replace this time. I’m not going to risk it if there is any question, saving lots of money doing it myself anyway. Also wondering if I should consider doing a valve job this time around. The car still runs great and doesn’t seem to exhibit signs of valve wear. It doesn’t even use excessive amounts of oil.
