What are the purpose of these two plugs? On my 2020 6.4L the lower one was dripping oil when I got it. It would drip down and then drip off the bottom of the oil filter cooler. I snugged it up (it was loose and turned a turn or so before snugging up and this was at literally 500 miles or less when I noticed it) and it stop dripping but I have always wondered what these hex plugs are for are they just passages that were drilled for engine assembly that serve no purpose or do they serve an actually purpose.
