OS 12 TZ engine
I'm pritty much a noob here, but anyhow my question is with the OS 12tz engine in my tg10mk2. The car can be pushed forward and reverse without the motor installed. The motor has been broken in already. With the motor installed into the car, the car can still be pushed forward, but when pushed in reverse, the back wheels would lock up. I removed the glow plug, put some after burn oil in the engine, and the car is able to reverse, but the wheeles would be jerking in reverse, but freely moving. when the glow plug is installed, the wheeles/car will not reverse.
Does anyone know what the problem could be?
