Been getting 30FF codes and I opened the hood the other day to see what was going on and saw some liquid, looked like how oil looks like after it's been leaking but I'm not sure how you would tell oil and other liquid residue's apart.


Here is a picture, it's the circled stuff in red. It was also on the pipes under the pipe circled in blue. I'm thinking charge pipe but it doesn't look loose (that might not be the charge pipe tho)
