How would you tighten that properly?

 

i'd assume you would hand tighthen it, then screw the o2 sensor in, and use the o2 sensor to tighthen the whole assembly. should only be a problem to remove it

 

That's the way I'd do it. To remove, use a pipe wrench if it won't come off with the sensor. Wrap it in rubber if you don't want to dent it, but then, it's under the car, so who's gonna see it anyway?

 

its aluminum! use a pipe wrench and tear through half of it! they should have made it stainless so you could just weld it in!

 

trying this today......lets see what happens

 

I apologize for pulling an old thread, but I got a P0141 (secondary oxygen sensor heater), checked voltages per the Helm manual, ordered an 02 sensor, and upon pulling the secondary O2 out, disovered my cat and O2 looked exactly like these pictures.


New cat is the only fix, right?

Thanks Dave. I suspect I will need a working cat soon enough.

 

Bummer. Those babies aren't cheap unless you get a used one from someone who doesn't use it anymore (t. pipe).

 

Looks like $500 is the going rate from the auto parts chains.
