O2 Sensors color

[ctrlraven]

O2 sensors were removed from the exhaust minus the front drivers side since it's in the manifold. The color of the O2 sensors are a dull white color, not fully covered but most of the tips are. Is that a normal color for them or does it mean I'm running rich or lean? Just curious and thought I'd ask since I have another 3 or 4 hours sitting here at the exhaust shop. lol

Here you go:
Oxygen sensor by observing the color of the top positions can also be judged failures:
�� light gray top: This is the oxygen sensor's normal color;
�� white top: from silicon pollution, this time must be replaced oxygen sensor;
�� brown the top: from lead pollution, and if serious, must also replace the oxygen sensor;
�� black top: from coke caused the exclusion of coke the engine malfunction, it is generally automatically remove the oxygen sensor on the coke. "

I'll post pictures of them when I get home later on. I think the color is more light grey than white.

I couldn't believe how easy all of mine came out. I think I might just replace them since their relocation spots are easy to get to.

Passenger side front & rear O2 sensors (Left is rear, Right is front). They were actually Gray on the top of them. I think I might just go ahead and replace them since I have almost 148k miles on the car.
