I meant the hole was drilled to keep the adjuster from turning. I have noticed when screwing in the adjuster, it got harder to turn when it went past that hole. Did not think oil would come out of there.
I always thought the rockers were tapped with a interference fit so the adjusters won't back out and without a lock nut. I am a long ways from my rockers right now. Anyone have one handy? Is the adjuster threads tapered or are the threads in the rocker interferenced?
