Found a mysterious fluid stain on engine cover. No visible leaks nearby. Any ideas?
I checked under the hood today to check the engine oil level, and I noticed what looks like a leak (fluid stain) on the engine cover, as shown in the picture.
I used a flashlight to inspect all the surrounding lines and hoses, but I couldn't find any visible traces of a leak nearby. My car is still brand new, and it has never been serviced or worked on by anyone yet. Also, I am 100% sure this is a fresh stain that wasn't there before.
What should I suspect or look into here?
Any advice would be highly appreciated!
