Hello. My first posting, after reading for years. Thank you for all the help! I’m working on a Blown head gasket on 06 9-5 2.3T. Someone drive this one hard. Head is warped .017” end to end. Engine shop is saying it can’t be resurfaced because the camshaft bearing surfaces also show a wobble when they use a round straightedge. That it will cause camshaft to bind and uneven wear once re assembled. I’m interested in what you experts think?
