Rust \"on engine\" Hey everybody, hope everyone is doing well. Haven't been on in a while but that'll change cause school is finally done! Now my actual question. I was checking my oil (since I am still burning some) and noticed I have rust on all 8 headers coming out of my engine and rust on the metal part of the spark plugs. There also seems to be dirty pastey like "stuff" (seems like oil and dirt) on my valve covers (I think that's the right name, the flat part on the top with the hole I put the oil in after it burns away, lol). Any ideas what's causing this? Thanks in advance!
