Thank you moses
I had the same thoughts with shim stock and tubing.I am wondering if some one had done this earlier in this engines life and used some kind of soft material and when the machine shop boiled the head it just turned it into a solid mass that was the source of my original plug leading to the right head not oiling (the one I drilled out).I would just as soon not pull the engine out and all apart to see what I can find if any thing,but I can it is just a toy and not a daily driver, I'm just not sure what I would find. What would you do ?
