2008 Forester X Premium 5MT
Subaru has specified in every manual where torque to yield bolts are used and to replace them when servicing.was told by someone today that the cylinder head bolts might be "stretchable" types in that they elongate during the tightening, and cannot be re-used. Any credence to this?
They have never specified to replace head bolts on any EJ25, there have been many who have sent emails to SOA on the mater and have received emails back stating they are reusable.
However I do replace them on my own stuff, but have reused many with out issues for people who did not want to spend the few extra bucks. Your call really.
