my o2 bung was welded into the side of my piping by the shop i brought it to for the exhaust.. and on the zietronix instructions it says that you cant have the wideband mounted sideways because it could damage the wideband... i was wondering if it is really that serious of a problem?

 

The wideband fluid will leak out!

j/k... it's just so that you don't accidentally bump the body of the sensor with road debris AFAIK.

 

Actually an O2 sensor should not be mounted horizontal because carbon can build up in the tip.

When I got my L2H2 the mounting instructions said to make it at least 10° above the horizontal. I have mine mounted at about 20° from the horizontal and have had zero problems.

 

they are really supposed to be mounted +- 15* from vertical... having them horiznotal or below would possibly allow condensation to enter the sensor causing internal damage

 

thats news to me. it cant be that bad.

 

Wow, great information. Thanks guys

heh, me too. Oh well, I'll fix it when I make a new downpipe. That's the beauty of a $40 wideband sensor

 

I think it depends on if you are going to leave the sensor in or not... I mean, if you are only tuning with it, then there won't be time for condensation to build on it.

But, if you are installing it permanently into the car, then I would make sure to mount it upright so the condensation doesn't damage it...

my thoughts exactly !

 

well, i think im going to have to have the shop that did my exhaust fix it for me then. this is on my car and i went to install the wideband today and the bung was on the side. to say the least i was a little mad at the shop. i am going to make them fix it for free

 

They are not supposed to be dead vertical because of heat soak into the upper portion of the sensor seals. They are not to be horizontal or below horizontal because condensation will accumulate and may freeze and crack the ceramic in areas with a winter climate.

Optimum is between 100 degress from the bottom to around 170 degrees, or 105 to 165 degrees if you prefer. If you are horizontal and not in a freezing area you can probably get by.

 

How about below horizontal, as in, on a downpipe?

 

Not having a picture and words being so apt to misinterpretation, here is the guidline: Mount the thing so condensate will drip out the thimble. That's what you are really after.

If the downpipe is going straight down, normally all the bung locations would put the sensor flat. Thats good for heat, but non optimum for condensate if you are in a winter climate. If you are in the frigid north, cant the bung about 5 or 10 degrees, so the tip points downward. If your in Cali, you should be able to run it flat.

 

Always love reading your posts, BigMoose.
Pretty much exactly what i wanted to say, but i have a hard time putting my
thoughts into words. Your posts are always informative, and worded in a easily
understandible fashion.

 

alright thanks. i will only be keeping the wideband in for the summer probably.
