I had a 95 toyota truck with the 3.0 liter engine. At about 190,000 miles I had the head gasket issue. Near the rear main seal the aluminum on the block had corroded and that is where the leak was. A couple of mechanics told me they would not guarantee their work because of this so I did not replace the gasket. Instead I used a 'nano technology' gunk that you poured in the radiator. It worked to stop the leak of the head gasket. It also plugged both the radiator and the heater core which I had to replace.
I sold it at 225,000 miles and the guy who I sold it too now has over 300,000 on that motor. Go figure.
I really liked that little truck, I felt it had enough power for what I expected it to do, but I moved up from a 4 cylinder Nissan to it so I may have had low expectations. MPG was only about 20 and that was a disappointment.
