There's a breather tube with some kind of filter or valve inside going from the valve cover to the air filter. I had to put some electrical tape around it to keep it from popping out while driving (for now). Should this be a clear airway? And the what is this part called so I can get a replacement. Please let me know, because on the way back from Oregon to Washington, this popped out and splatter oil all up inside the engine compartment. (I did cut back some of the excess tape around the tube opening... eventually).
