check that valve out. all the rest have a nice coating of carbon, but not that one. yes, i know there is some oil, thats from some brake cleaner i squirted in the port to see if it was leaking. comp test was good. didnt bother to do a leakdown on it. but its the right side and its the side i had issues with. it looks like it might have at some point seized a guide, but i havent been over to the shop to drop the valves yet. anyone have an idea of why there wouldnt be carbon on this?? im no tuner building genious, but no one ive asked has an idea.
i should add that the valve is that color. the blackness of it isnt from the brake clean. there is only a small amount of brake clean on it. there is only a little carbon on the face of the valve. just like it looks. the brake clean is around the seat and just above the plug hole. and no, im not reinstalling this head.
