Your last oil change, how much did you put in? seeing any oil leaks on the engine itself underneath?

My first thought is a lifter issue. Depends on the noise cause it could also be the cam pads/chains, but that is usually persistent not just on startup. I would put something in like seafoam right before your next oil change. Such as drive it for 20-40 miles with seafoam and then change your oil & filter. Let the oil drain for an hour and then fill. If it helps then maybe do it 1 more time.

I added 9.25 QTS MB 1 10w 40 Syn adding 9 then checking the levels I add the other quarter. The attached pic shows the spots I see underneath. I assumed it was old oil on the engine block with A/C condensation but I could be wrong. I've only seen a full oil drop once this year and the rest of the time this. The paper was new about 45 days ago.
