I've got a stock 94 and I have a bad oil leak. You can smell the oil burning after driving it for about ten minutes. A Mazda tech said that one of the turbos was leaking.. Here's my question..If I replace the turbos with new or rebuilt ones will this lead to me needing to replace the motor? the car has 96k on it now. The tech seems to think that if I put a new turbo it will blow my motor really quickly. Is he correct? We are pretty sure that it is the turbo leaking and not any lines. Thanks
