I just took a close look at my engine as I was hearing a weird noise coming from there. I noticed that the engine has this weird sort of etching or something on it. It isn't smooth aluminum like I'd expect to see. It is right below the valve covers. Is this a common thing? I didn't even know what to search for using the forum search function.
I just expected to see some smooth metal there. Instead I see metal that looks like it was dried in saran wrap or something. Does everybody's have this, or does anybody even know what I'm talking about? I'll try to get a picture of it if my explanation makes no sense.
