So I switched my valve cover, a week in I started noticing that the paint is fading on the intake cam side. Have ya ever seen this before? Is my cam hitting the cover? It's a b20 with ls valve cover. https://imgur.com/a/z8zCs Here's a picture
Unless your cam gear is completely fucked and grinding it's way through.... But it's more likely that it's just a crappy rattle can job that's starting to flake.
Also, there's no difference between B20 and 96+ LS valve covers.
Well that's odd... though it looks more like someone rubbed it off with a scotchbrite pad than heat.
Start the car, then hold your hand on the valve cover right there, see if it gets hotter than the rest of it in that spot.
You should feel a bent cam gear when you drive the car, would probably vibrate/shake like hell, but maybe the belt is rubbing the cover for some reason? If it were me I'd remove the valve cover and inspect.
