Hi,
I checked through two manuals and there is nothing indicating anything that isn't standard. So, with that, to loosen it, turn it counterclockwise. Turn it clockwise to tighten.
If you are having trouble removing it, if possible, use an air impact gun. It should take it off for you.
Now, as far as the distributor, it is the same standard thread.
Let me know if this helps or if you have questions.
Take care,
joe
