I checked things over quickly this morning. Yes there are expansion plugs in the end of the tube. I forgot that the last rocker arm support at number 6 cylinder is fixed to the tube and yes it is plugged. I can see it on the parts breakdown now too. The oil is leaking from between the rocker arm and the support shaft (bushings) on the side between the intake and exhaust rocker for number 6 cylinder. It was running from the other rockers too number 6 just had the most.
In other words it seems to support my theory that the bushings are wore and may need some attention. I remember while cleaning them they did show wear enough that the base metal of the bushing was showing through.
Can these rockers be rebuilt with new bushings? How else can this be repaired? They are listed at IH for $113 each times 12 so thats not an option. Going to do some checking for used ones.
Also while starting it this morning it started good but still got one puff back up the intake. That's going to be another problem that still needs attention. I have set the timing by the book with it at 2 deg BTDC till I had spark at the points. What else could be causing this? I don't think its sticking valves anymore cause I was oiling them with and oil can last night to supplement what was not coming from the rockers.
