The clutch. That's it!
Toyota's always have and always will run forever! This truck ran on the road until wrecked in 1998. It was towed back to my house completely unreconisable. I got in, turned the key and it started right up!! I could of sworn it was bound for the junk yard. The engine wasn't damaged at all. It still runs as an unregistered woods truck.
My toyota has over 237,000 miles on it. It has virtually no problems except oil, it uses a quart about every 200 miles..
I totalled my old toyota, flipped and rolled! when I got it home it had a busted radiator, broken cap, and split oil line to gauge. Turned the key and it still fired up fairly quick and ran on three cylinders, spurting oil, and water. got a new frame and body, and yes the engine still gets me to work every week, and is my play truck on the weekends!
