The sensor from hell.

[masterchop]

This is not intended for the garage. I've already had advice from there.

This is just a rant. Let me begin:


F@@@@@@@@@@@@@@@@@@@@@@@@ saaaaaaaaaaaaake.

The sensor that fits in the top of the exhaust will not stay put. Do it up. It comes undone. Do it up really tight. It comes undone.

So on to harsher measures. Loctite thread locker. It comes undone.

So in desperation I called my local garage and asked if they could weld the bastard on. They said no due to the metals and said what I need is chemical metal.


Went and bought chemical metal. Tested it. It sets like concrete. Applied to bike.

The heat broke it.

It came undone.

To be continued.........

Find a bolt that fits in the hole and bin the sensor.
Tried wrapping it with PTFE tape?

Would it withstand the heat? I know it goes on hot rads but exhausts are crazy hot.

Dunno, wouldn't hurt to try.
Its the same stuff wot they apply to frying pans and such and they does get fairly hot.
There's probably proper exhaust gasket tape available if you look on't inter web.

Try the old fashioned way - wire lock it. Drill a small hole across one of the points of the nut and wire it. Like this: http://www.ebay.com/itm/BMW-safety-wire ... 0454100797" onclick="window.open(this.href);return false;

Has it got a copper washer fitted on it. Most exhaust sensors on vehicles, have a copper washer to act as a seal but also allow for expansion. If not try fitting one to see if that helps.
Also tightening the sensor when the exhaust is hot and already expanded due to heat, but be careful not to burn yourself.

If this fails you could try a star washer.

Thanks for all of the suggestions. Ive tried something and just waiting to see how it goes........i hold my breath

I don't think you should put any tape or lubricant on a sensor thread. I was taught not to anyway.

A soft washer like the copper washer mentioned above would be my first choice, a spark plug washer would probably be too soft unless you are tightening onto a flimsy pipe that won't take much torque.

How about the putty that is used for sealing joints on exhausts?

Ive used Q-bond recently, wonderful stuff, check it out on youtube.
