Salvage yard pricing doesn't lie, the more it costs the higher the demand. The higher the demand, the higher the failure rate. Duratec I4 and V6 motors: $500-$1500. Hyundia/Kia 2.4L Theta II : $2500-$3500. GM 2.4L LEA Ecotec : $2500-$3500. Chrysler 3.6L: $1500-$2700. GM 3.6L: $1500-$2500.I'm going on 20, seen some shit. but hey to each his own right, whats that saying... one mans trash is another's treasure, you can have ALL of them lol.
