I'd like to replace and upgrade the Valve Covers on my 2004 XLT 4.0 ... what are the right choices to look at ? Are there aluminum Valve Covers and are they worth hassle/cost ?
I believe the one I saw was a sohc engine, valve covers were big like on the sport tracs, not like the 94 ohv explorer we also have. I haven't found any pics online, I want to say it was 97 or 98.
