Need help getting lube for my bung hole.

Made you click didn't I?

What anti-seize do you recommend for use with wideband sensors?

I understand there is Nickel based stuff, petroleum based stuff and copper based stuff. I grabbed a tube of the petroleum based stuff. Is that good? Anything to avoid?

Where are the bung holes? What a rip off...

Nickel anti-seize is the highest temperature, then copper. The petroleum based stuff is probably going to burn up in the high temperatures in the exhaust. That said even the nickel shit will cook over time. I use the nickel stuff on exhaust ducts on turbine engines and fuck me you pull them apart after 5 years or so and it's like you never put it on there at all.

So as long as I apply it to the threads only, anything is ok? I thought there was something that if you got it anywhere near the sensor it would ruin it. No?

High temperature anti-seize, sparingly applied to the threads, is the correct solution and will not harm the sensor if you don't use an excess amount of anti-seize. The best types to use are the metallic compounds.
