Hei, i have Toyota rav4 2002 with 1cd-ftv diesel engine. First the turbo made a lot of sound and then the engine sounded like something wrong. I stopped the car. I check the oil and it was empty.. i filled oil and try to start it but the engine was stuck! I try aigain next day and after some attempt the car Started. But now IT is coming a lot of smoke! The turbo still make a lot og noise but the engine sounds fine. So do i have to change the turbo or is IT something Else wrong?
