Exhaust Leakage

I just posted this on the Brick Board:

My brick rasps awful loud and I went under and found where it’s leaking. It’s at the flanged fittings where the header meets the cat. converter. I got a generic exhaust gasket from a local shop and it fit correctly. The old one was held on by one out of the three holes.

I tightened up the bolts but it still leaks. When I hold my hand around the back of the flange for the cat converter I can feel exhaust leaking out. It’s on pretty tight though, so I’m not sure why it would still be leaking. I tightened each bolt equally. Could they be too tight? Bad gasket? Bad flange?

    I got some notes on the Brick Board that it’s not a gasket, it’s an exhaust sealing donut. The later bricks have flanged pipe ends, so it needs a thick, angled piece to fit between the pipes.

    I need this.

    That means it was installed wrong from the mechanic, because there was a worn gasket in there. NAPA doesn’t have the part listed, and it’s not documented in the Bentley or Haynes, except for turbo models, which have a larger outlet. Oh what fun.
