Default gone thru 10 O2's PLEASE HELP!

Ive gone thru about 10 O2's and i dont know what is making them go out.

I have an Open cutout with ORY and no cats.

What could be making them go out every 3-4 weeks?

I recall reading a post warning that WD40 or some type of silicone spray, sprayed near the sensors, could cause them to fail. Also mentioned was a certain gasket sealer, used in header install, that supposedly caused failure. Just my cloudy recollection though.

Agreed you must have some sort of contamination issue going on ...leaded gas, certain octane boosters silicone, silcates & bunch of other chemicals that can build up a coating on the porceln tip of the o2, thus degrading it.

This would be true if its the rears, but if its the front ones this is bad if it keeps going out. i heard once before that coolent was leaking on it and crapping it out, really hope its not that. are you using anything that isnt normal around the engine?

make sure they arent having rubbing issues or header melting issues. I have Hooker headers and if Im not careful the left sensor will wear through the wire and short out on the shielding.

I have to second the coolant issue. If it is the driverside more than the other check the head gasket on that side first. Do a compression test and let us know what you find. Also i have the same heat problem i checked under the car and the drivers side was only the sensor and the wire couldnt be found.

I know if you used any kind of RTV silicone it will mess the sensors up, along with any kind of cantaminant in the fuel system. Whatever the problem, good luck with it.

Put a catch can on the pcv hose to cut down on the oil going into the combustion chamber. Are you using some extensions with long tubes. I know that I had a problem with the connection on one of my extensions that was turning the O2 on and off randomly, and setting a code. Just a couple of things to try out.
