First I would start with a heater hose or something like that. Have someone shut down the engine while you try to hear which side of the engine the noise is coming from. If something inside the engine came apart it could have put metal pieces in the turbo and they could be bouncing around in there. You could have a rattle that sounds like a jingle coming from the blower vanes rattling back and forth when the engine stops. Last but not least, you could have an air box cover that came loose and rattles when the flow of air isn't pushing it out. That engine should have cast aluminum covers on it, but if it was converted to a turbo model, the old stamped steel ones could be still on it. |
