see this little tiny hole inside the little hole?  That is how the oil gets to the cam........

do you see what happens to that rtv when you the 2 parts squish together? You get those little balls that hang out on the out side of the motor which we pull off or wipe off? Well those squish out on the inside to...but you don't see them till they make their way through the oil passages and get stuck at that little hole and your cam burns up the top end...

now ask yourself how much rtv did you use? Only takes one little ball to leave you on the side of the road trying to find a trailer or truck to get home.
