I've been thinking of this for a while, but have never seen any for sale. With all the concern for getting oil to the rockers on a Y-block, it seems to me that a pair of clear plastic valve covers would be awesome. Depending on the durability, they might be short-use diagnostic tools or if strong enough you could leave them on for good. And it would add a bit of cool factor. Is there any reason this could not be done? Has anyone seen such a thing for sale?
