I have been told many things, my 94 has 31k on it..

original gaskets but no signs of weeping.. oil is great.. i was thinking id run it at least another year before i spent the money on gaskets and tore it down, it seems like a job i could do myself in a garage. Is this head gasket thing really that big of a deal? Would it cause a full engine rebuild or something if it just totally went out? my understanding is they just eventually start to weep onto the outside of the engine and burn up all your coolant. And I've heard everything from replace it now or just run them to problems start.. What is your concensus? My car gets driven every week at least a few times.. its not just a parked and sitting kind of car i changed the coolant out first thing when i got it last year and i constantly check fluids especially for 100 mile plus drives.. car lives in a low humidity dry area (west texas)
