Its good to here you want to keep her running..Here is a sugestion though..Is she blowing smoke of any kind or color..If not all the valves and valve seals are fine..If there is no significant powerloss,knocks or chattering then the bottom end is fine..These motors have been known to get well over 200k miles on them with out a rebuild on them if taken care of..Now it probably wouldnt hurt to change out the cam seals and a few other gaskets on the external..You can get all the gaskets from www.advaceautoparts.com ...They all will only cost you about $140 for all of them and that is also a new head gasket and valve seals.. There is a online repair manual as well -> http://www.cygnusx1.net/supra/librar...in/IN_001.html

These cars are actually very easy to work on once you get started..Any other ??? just ask and ill be glad to help..
