I just had a stupid/cool idea...

So I was thinking the other night (since I'm a gearhead I'm always thinking about cool new stuff to engineer). I don't know if this even exists already or if it will even work, but..... I was thinking about making some clear valve covers for my truck. It would be pretty cool to pop the hood and show off the running valvetrain to your buddies. The only problems are do they make plastic that will stand up to the heat and will the oil from the rockers cover up the underside of the covers rendering the idea useless? They already have clear diff covers, so why not? I figure if you make them tall enough, they wouldn't be affected by the oil splash. Just an idea...
