I have a 2000 gt. Bought it used, 3 weeks after owning it starts using about 1/2 - 1 qt. Of oil a week. So take it to a Toyota dealership and they say our best bet is to have the engine re-built which cost $1,500! so the engine is re-built everything is fine for about a month then it starts using oil again and by this time there's no warranty. So I continued to keep driving checking and adding oil. 5 months later I'm driving down the highway the temp. Gauge goes all the way to hot and drops right back down. A couple of days later the engine blows up. After having a new engine put in it, engine costing $2,000 for a used engine. The temp. Gauge does this again. . . Come to find out air is in the coolant system and Toyota never got it all out the first time and that's why it blew up.
When driving vehicle would jerk. Engine would become noisy and shaky. Would fail to idle properly. Clutch pedal would go to floor and failed to return to original position. Not able to shift gears. Have taken vehicle to dealership. Was informed by mechanic that problem were the valves in engine.
