Hey guys, I recently picked up another truck. This one is a 2018 with 40k miles on it.
Yesterday I was swapping out the spark plugs and noticed a good amount of oil on the driver side pooling on the intake manifold and valve cover.

I brushed it off as a clumsy tech that spilled some oil at the last oil change and continued with my plug swap. Later that day it dawned on me that I should check to see if it was clean or dirty oil.

Long story short, it's dirty oil and I was unable to find a clear source of a leak.
It didn't seem like it was coming from any particular area.

Here are a couple photos...

Anyone know what these two plugs are for? I have oil all around them on both sides but not pooling in the bolt areas like this photo. Thanks.
