I don't think that it's a very good idea to "seal" the oxy sensor. I
believe that it needs to "breathe" to sense ambient oxygen content or it may
not work properly.

Subject: Water in Oxy sensor.
If any of you read my last post on Digitool readings and oxy sensors a few
days ago you would have noticed that the conclusion was that the oxy sensor
I had was shorting internally and Voltage from the heater was corrupting the
signal to the ECU. I was reading several volts at the Ecu (through the
Digitool) on several occasions. This was a intermittent problem which
disabled the van- USUALLY associated with rain (and I live in Seattle). I
replaced the sensor yesterday with the "F**D" connector oxy sensor (U.S.
part # 13913). Van runs great and all readings are normal.
So I decided to look into the old one to see what I could find. I ripped
the "top" off the sensor where the wires exit and found WATER inside the
metal cap and the rubber plug--- around the connectors for the three wires.
Also It looks like there may have been water in the main body of the sensor.
So now I am wondering if there may be differences between oxy sensors? Is
it possible that some sensors are more suitable for exposed mounting like on
the vanagon? The old sensor I opened was also a 13913 F**D sensor with only
10-11K on it. Anyway I intend to seal my new one well with oxy sensor safe
rtv silicone.!
