Exhaust Leak
So I have an 08 but can't figure out where to start with this exhaust leak.
It is likely near the exhaust headers or downpipe as exhaust smell comes into the cabin if i have my HVAC to vent from outside. Any suggestions for techniques or places to start looking? Thanks |

With 99% certainty, it is the donut gasket between the header and the down pipe. An '08 is past due for replacement if still on the original Open the hood, start the car, and reach into that area with an open hand. You should be able to feel the gases puffing against your fingers.
This is what the gasket in my '06 looked like in November 2011. I am once again due for a replacement. Sent from my Elite_5_5_Octa using Tapatalk

^ +1 My money's on WeeYari's diagnosis. Mine was gone, but so was the entire flange. The cat pipe had completely separated from the manifold and was hanging down about 1/4".

How hard is this job to do it myself and what are the steps involved to change out the gaskets and bolts? Thanks

That's probably the best thing to do because they do tend to rust badly with moisture and continual heating/cooling cycles. That said I have removed pretty rusty ones by soaking them a few times with ReleasAll or similar and used my electric impact gun. I can't see a muffler shop charging much at all to replace that donut.

I had the same problem, no leak, but a noise and couldnt figure out where it was coming from. Turned out to be this flange gasket. Toyota wanted almost $50 for it and I got it from a local parts shop aftermarket for $8. Had to sand it a little to get a perfect fit. After that it was fine. Reused same bolts and put antiseize on threads.

well, I started on this job and the bolts were so corroded that they both snapped.
I may well call it a day |

I was able to cut away the bolts between the flanges, but will need a longer drill. I replaced the donut gasket and clamped it shut with a U bolt until I come back to it after purchasing the correct parts
Noise is gone, but now I have a P0031 fault code. I wonder if I damaged the O2 sensor while messing around? nightmare fuel |

Maybe the wiring which is not far from the flange. Could you have nicked a wire with your drill bit? The downstream sensor has 4 wires. Not sure about the upstream wideband sensor.

So I'm guessing my P0031 corresponds to bank 1 sensor 1 which is the upstream.
The more difficult one, should I go from the top or bottom? decided to use two of these flange repair https://www.autozone.com/emission-co...277182_0_17365 |
