I had a leak in that area that I wiped up for years because I thought it was leaking from the cam carrier/head joint. Then I had to take the engine out for a clutch replacement. I decided to adjust the valves using the backside method. I found that one of the lower rocker arm shafts had broken at the slot where RSR seals are installed. Of course the rockers was leaking into the lower spark plug chamber (my engine is twin plugged). When I replaced the rocker and reinstalled the engine, I have not had a leak in that area since.
