Valve covers, being metal, tend to last a long time. Gaskets are usually the source of top-end leaks. Of course, nothing is perfect and a valve cover could have a casting flaw the creates a weak spot that could eventually crack under the thousands of heat cycles it'll see over its lifetime.

Perhaps so. I don’t know the issues with those. But if I was told I needed to do it I would expect to be shown why and would probably not need to ask advice on a forum. It seems it should be pretty clear cut and obvious.
^i say that because the vq35de tube gasket seals werent replaceable during those models so owners had to replace the whole cover which was not cool/fun because the tube seals always leaked sooner than later lol
