Can i use the steel valave covers on my 2003 qx4? I wouldn't think there would be an issue, but what would your take be?

I haven't seen an issue with plastic valve covers, they don't warp or rust out like steel can. They did make a change the PCV system when they switched to plastic valve cover. I'm not a fan of plastic by any means, but plastic valve covers are okay.
