I have just received and mounted a Lycoming IO-390 on my RV-14. Maybe I am not understanding all that I am reading, but one source says the Expansion Plug must be removed for constant speed props. That's all they say. Another source also says the expansion plug must be removed AND another expansion plug installed behind the "oil valve". If this is true where can I purchase this phantom expansion plug and how can it be inserted behind the oil valve?
I'm still trying to remove the outer expansion plug with no luck at all. Per VAF thread I have drilled a 1/4" hole in the plug, but where do I go from there? Tried inserting a Phillips screwdriver in the hole and prying it out but it won't budge. Any suggestions? I'm stuck!
