Stains on the engine hood

Does anyone else have these stains on their hood?
I really do not remember if they are since I have it, I bought it with a few kilometers.
In the workshop I have not asked but I know they will say that it is normal, everything that happens to the car for them is normal. I'm not noticing strange behavior or loss of power ... I think.
Looks like dry motor oil

well i track the crap out of my car, run it hard and have a stage 2 renntech and its a daily driver.

40k + miles and onward

as i said, its blowoff, i dont have catch-cans so that was my guess.

I noticed this on mine as well - I think it appeared at around 10k miles or so in my case. Nothing abnormal, it appears to be a small amount of blow by. A catch can would probably solve it, but it’s such a small amount it’s nothing to be concerned about.

Drive and enjoy!

Trust me, he's right (he wouldn't say it if it wasn't true) and I yep also see those stains on my hood too.
