What is this when you have oil on one of the intake manifolds. One slightly more gunky the the other 3.
I Noticed it when I fixed a bolt in the cam rocker before. its only on the second valve back. I never bothered to clean it that time but now I have the engine apart I am pressure cleaning the bananas to see if it reappears.
I was hoping it was from left from the bolt that come out of the rocker and would have dried by now.
