Oil Galley plugs at Camshaft

Who was the brain surgeon who did that.

Take the pipe plugs out and throw them in the drawer for something else.

Don't bother with the soft plugs either.

Bolt the cam plate or tensioner on there and forget the oil gallery is even there. You don't need to plug that off and tapping those holes is beyond idiotic.

Then call Chrysler idiots, because I see a lot of factory blocks with short pipe plugs there. Sometimes it's not about "makin stuff hard" it's about "puttin stuff back like you found it". Just because you haven't seen something, doesn't make it NOT so. You crusty old geezer. lol
