2015 Ford Explorer P.I. with 3.7 V6. Oil leaking from the front of the engine but not the main seal. You can see oil just on the front 2 bolts but back from there everything is dry. Oil pan gasket RTV going bad?
Where is this oil leaking from?

No that's the block. Checked those bolts and they were quite loose. Tightened them and a few others that were loose to specs. Not leaking after a half hour.
You might have to drive it to see if it’s fixed. Thermal cycling will be the true test. You may get some residual oil for a while.
Just my $0.02
How about cleaning it off (best you can) and adding some Leak Detecting Dye to oil.
Then check with UV Light.

They are everywhere. On the valve covers, intake, radiator, etc. Not sure.
Those look like markings from the local auto recycler
I have seen some fleets mark mileage for when services were done like that.
Timing cover, valve cover, oil pan are all common leak points. Timing cover and oil pan seal with TA-357 silicone. If you are in there with teh timing cover off you might as well change the water pump and chain tensioner, maybe chains and guides too.
Agree, looks like salvage yard marks.
They mark the same part multiple times?
3 places on the valve cover, 3 times on the intake. WTH?

Probably to mark all the major pieces so they can track where it all came from in case items get sold in pieces. I bet there is a overheat tab on the block as well.
