'91 Metro has / had multiple leaks in the exhaust. Ended up buying a new cat.assy. Installed it last night - there's a small leak where the flanges mate to the muffler assy. That is an easy fix. I still hear a leak coming from in/near engine compartment. New gasket is on the flange that connect the exhaust manifold to the cat.assy. Didn't see a downstream O2 sensor hole in the cat.assy. when I inspected it. Only thing I haven't replaced is the exhaust manifold/gasket. Hope the PnP has one for a 3 cyl. Find out this weekend.

I know manifolds do leak and gaskets do blow but I have not seen it happen on Metro yet. Keep us posted. |

You may want to look very closely at your exhaust manifold, on my daughters 99 before we rebuilt it, I didn't even see them when we bought it, but it was cracked in three places... Just something you may want to check.. |

I have a 1.0 exhaust manifold if you need one. I'd like $35 shipped for it. |

Littlest Hobo developed an exhaust leak that drove me crazy till I figured out that it was the manifold to cat pipe connection. New gasket and Cat about one year ago. I could hear the leak when driving with engine under load but not when parked running. I had to shim the springs on the connection bolts to create more pressure holding the connection together. End of my leak. |

Mine is a red and rusty.
Damn. Which I would have check this before ordering one ($75)
This leak...I would be surprised if it is the Manifold to cat flange. A) I put a new gasket there. B) It took me ~30 minutes to get it put together because the springs are so dang tense, I had to eat a can of spinach before tackling the beast. I think the manifold is the orginal. |

...well, I don't know if the leak was the manifold (or the gasket between it and the head), but I got the new exhaust manifold in the mail yesterday and put it on last night. It passed safety & emissions inspection today - good for another year, and the last time it will require emissions. In VA, emissions is not tested on a vehicle if it is 25 years or older. |
