OK..so here it is. It appears my roomate blew her head gasket on her 99 Taurus V6. 120,XXX miles or so.. Single overhead cam..is it worth fixing or trying to find a lower mile engine for $600 or so and doing an engine swap? I am use to mustangs and imports so I have some knowledge but not on this car. What all is involved..how long should it take..and is it worth it? I have the manual for the car but it really doesnt seem to show much (Haynes) so any response would be great!
