There is a previous tutorial post, that describes a procedure for re tightening the cylinder head in order to alleviate a head gasket leak. Does anyone have any experience with this? Is it a waste of time or did it work? The post speaks of a TSB for model years 1998-2001. I have a 2005. Would you think this may apply or is it a different engine (i have a 2.3T)? The post is titles "Retightening of cylinder head bolts - Saab 9-5 M98-M01" (Procedure to remedy coolant/oil leakage from cylinder head without gasket replacement)
