Wideband O2

[340inabbody]

Guys has anyone installed a Wide Band O2 bung on a long tube header collector while connected up? Let’s assume I have a decent 360 angle to weld it. I really don’t want to yank the heads if I don’t have to. Just curious if this is a common practice or a definite no no.

Thanks

If viable, I'd put in the pipe right beyond the reducer.

Downstream from the collector like 6”?

Yes just disconnect your battery and you can weld them on the car with out hurting anything besides burning something while welding of course.

That's what I did. I did lose the sensor after a couple years. My buddy said I should have went back more due to heat but IDK.

Should be in the collector half wayish depending on interference possiiblity and optimal @ 3 oclock or 6 oclock position .

Yes. I've done it twice on two separate cars. Both work great. Take care on how the sensor is positioned. The plug end part must have a little upward angle to avoid water pooling into the actual sensor part (part that is actually into the exhaust stream). Wire it up and tune away!!

Did you use leaded gas?

Unleaded

Interesting... Leaded gas kills these things... not sure why you "killed" one so quick... maybe it was faulty

Faulty? Maybe the car just needs a good thrashing? Faulty knows how!

A big killer of the sensor can be using silicone that isn’t O2 sensor safe.

IIRC , Permatex says if it’s automotive and their name is on it it’s sensor safe.

If you are buying silicone at a hardware store or similar it’s probably not sensor safe.

That too!!!

6 o'clock? If you're talking about on the bottom, that is a hard NO! Never want the sensor to lay where condensation may collect. Now basically ANY position except 6.

I welded mine in the passenger side of my TTI's at about 9 oclock, looking into the header. No prob. 15 minutes.

i never used any silicone. A little anti seize on the last few threads is ll you need.

I mean non sensor safe silicone ANYWHERE on the engine.

It will kill the sensors lickety split. If there is non sensor safe silicone anywhere on the engine it will kill the sensors.

I’ve done a couple installed a t about horizontal. I have it plugged into my Innovate LM1 for tuning the carb. It’s a temp setup with the cable running out the window. It’s a great tool.
