Valve cover or timing election plate leak?

Noticed some dirt build up behind the inspection plate on the oil return lines. I took some pictures but obviously can’t tell where it’s coming from with all the junk, I notice a small stain under the corner valve cover but not much and also had some behind the timing cover inspection plate but the second photo under the plate look dry although I did try to I clean around the plate but not behind it where the bulk of the oil and dirt is. I can feel oil behind the middle of the lower inspection plate. After 2 months no change in oil level.
Seems like the timing cover inspection plate is a known issue. Is that what this appears like? Not sure if the oil sending line bolts leak? Definitely need to clean it up when I do the spark plugs here soon.

I can't really tell what I'm looking at in those pictures, but if it's down behind the power steering pump:
Get 4-5 cans of brake cleaner and the items below. Clean and replace that oil line. Decent chance that will fix your leak. If not, it's probably the timing cover seal and you have a much bigger job, if you want to bother with it.

I know you shouldn't have to replace a hard line like this, but I have seen several cases where the line itself was leaking, not the bolt or gaskets.
