if you have the money and the available time, i would replace the headgasket. that low of mileage. probably hasn't been replaced yet. if you can, pull the motor out replace all the gaskets and any hose that looks/feels bad. if you want a nice supra, it's gonna some serious money. trust me i know. it's better to do it right the first time. you should post some pics up. hope that helps alittle!
