I recently replaced the timing belt on my 92 Metro. I'm not sure whether there is a problem here or not. So, I'll simply describe the symptoms and go from there. The engine has 216,000 miles on it, but it still runs flawlessly and lacks no power. Yet at the same time, at highway speeds, it sounds different..."labored" for lack of a better term. Not to mention, now at idle, there is a growling sort of sound which started with the timing belt replacement. I'm at a loss. As a side note question, what purpose does the spring next to the cam belt tentioner serve? |

Maybe you have an exhaust leak or bad tire causing the labored sound? Also, when a timing belt cover goes on it sometimes ends up rubbing aginst the alternator belt. With the motor off, you may want to see if there are any signs of rubbing a wear mark in the plastic timing belt cover. I think the only function of the spring on the tensioner is help get the tension set before it is tightened up? |

No, there is no exhaust leak. I never had the exhaust loose and there wasn't a leak before replacing the belt and the alt. belt isn't rubbing on the cover. It's very close to the cover, but it always has been. |

well its obviously not the timing if your car is running fine. If it was off a tooth you would definetely tell a difference. I would let the car idle, get under the hook and take a look. then rev it and try to figure whats going on. |

Hi cheezit- Maybe the air cleaner snorkel isn't fully attached? Edward |

Perhaps we can get a video with audio so we can hear the sound?Try a Seafoam of the TB and see if there is any smoke in the engine compartment? So, at idle I'd recommend: For detecting "a growling sort of sound."Or a stick.
