white o2 sensor with exhaust leak under it?

[shifty2006]

What would cause the white o2 sensor could it be the exhaust leak below it.?

Burning oil, running too lean or too low ignition timing.

A leak after the sensor won't do that, one before it will.

Would you say I should replace the sensor?

Not unless the sensor is bad. Your car is running to lean, that is why it is white. This is not good.

Where would I go to check and see why? I did a compression test today and checked base timing if the cams line up it reads (from looking as level as I can ) 2° or if I put the crank at tdc looking at it the same way the cams look like this picture ill post my compression test and my cam picture.. I tried a guarenteed to pass cleanout for the smog that I still didnt pass might that be why the o2 is white? Also compression tes done cold motor fuel disconnected and throttle wide open.
