My dad just bought a 90 4Runner with a 3.0 V6 that has a rod knock. He wanted me to see if I could find some info on a replacement engine for him because he isn't very internet savvy. I have heard that you can buy low mileage engines that are pulled out of cars and trucks in Japan for a reasonable price. Does anyone know where I could tell him to look for something like that? He doesn't want to spend a ton of money on it because it is just a hunting rig, but the cheapest used engine he can find around where he is will run him about $1500 and a reman engine will run about $2k. Anyone have any suggestions? He lives close to Dallas, TX if that helps.
