Long story short the head gaskets need to be replaced and with the miles i was gonna do the water pump, timing chain ect with the miles on my wifes (now mine) 04 4runner V6 w/ 191K. All the dealers want $2500+ All the local shops dont want to do it or know how and are telling me to run it till it blows. I could do it myself just dont have the time with work and 2 kids. What would you guys recomend doing? Has anyone sawpped in a 4.7 V8 for the V6?
