i pulled the o2 sensor out of my 87 t2 today and the entire thing was covered with a white powder. it was just pure white, it wasnt even dirty just a pure clean white powder. does anyone know what this means and what is goin on with my engine? thanks a lot guys.

 

Mine was the same way on my 87NA....At least its not rusty or covered in oil.

 

hahaha, yeah good point. thanks for the info
