My 92 loyale has 145K miles.  Apparently it needs a new head gasket, it is leaking coolant.  It will overheat if I don't keep the coolant filled up.  My reliable repair shop says it will cost around $1000 to fix, they have to pull the engine, etc.  Is this right?  They say it is an engine "reseal job".  I am disappointed about the supposed long life of subarus, and lack of long life on my loyale.  My older 82 wagon went for 188K miles, no head gasket problem.  I was thinking about getting a new Outback.  Should I drop the $$ on this job?
