97 Exhaust Manifold Crack... what to do
Hey All,
I own a 97 Honda Civic 4dr lx and i have a crack in my headers where the primary O2 sensor is. I was wondering if you guys know or have any suggestions on what is the best route for me to go? Since the crank, i can't pass emission testing.
For the CO the limit is .41 and i tested at .52. Do you guys have suggestions on how i can pass.
I've read that Honda might replace the exhaust manifold under warranty. I also heard that if i switched the primary and secondary O2 sensors i might trick the computer and be able to pass?
Any help will be greatly appreciated.
thx.

go to NAPA and get a replacement manifold. 
or weld it.
those are your options.
BTW... those who weld their manifolds, I certainly hope you know how to relieve stress from a crack before you begin welding.

i've got an aftermarket manifold (not a header, just stock replacement) for an EK before for about $300 (if i remember correctly).
I'd rather do that, then waste money welding the cast iron peice.

ya, problem solved.
Except for the whole fact that a header won't bolt up, b/c the stock manifold has the cat attached.
If you're going to use an aftermarket header, you will need a cat (off a SI) and have your exhaust modded.
