Wideband Sensor Plugs. Check 'Em.

CBRich · 11-17-2010, 09:43 AM

So my exhaust started rattling a few days ago. Being out of town with work I couldn't fix it at the time. Eventually that turned into a terrible sounding exhaust leak. A friend here let me borrow his garage last night and come to find out one of my wideband sensor plugs had backed it's way out. Luckily his father-in law had a bad O2 sensor that I plugged it with temporarily.

So just a word of advice. Check your plugs. I had mine cranked down pretty tight but they still backed out on me.

A little bit of loctite probably isn't a bad idea.

I'll agree with that.

The service manual actually calls for the O2 sensors threads to be lubed with anti-seize and torqued to 37 ft-lb. It also mentions a specialized heated thread cleaner tool to clean the mating threads on the cats.

Yea, the plugs on my Berks were loose from the factory. Luckily, it rattled upon startup so we caught it right away. We just cranked it down tight. I doubt loctite will hold up to the temperatures that a converter would reach, even the high temp formula.
