Buddy has a 1999 Saab with in-line 4, OHC type engine.  It's been diagnosed
as leaking antifreeze from the head gasket.  Quote is $2200 cnd (22 hours)
to change.  That includes cutting the head surface.

Questions:  is there a reason to expect that the head "must" be cut without
examining it off the engine to see?  Engine is low miles - 65K miles.

Is 22 hour reasonable to re and re this head?  Or does this include the
machine shop time to rebuild the head? (I'm guessing that they wouldn't cut
the head without taking it apart, at least I wouldn't

Does this thing have a chain/belt that should be replaced anyway, so that we
could get two birds with one stone, so to speak?

Is this a known issue, or just random chance?

Thanks, guys.
