Hm, I wonder how much this issue had to do with the oil not being happy:

That right there is super hard rubber falling off around the valve cover bolt washer... Just found it. Maybe ya'll should peek at yours too?

Never would have thought to look there myself since I didn't even know there was rubber down in that valve cover bolt hole, but I'm in the final cleaning stages waiting for the wind/rain to stop long enough to put the head back on the block & whammo! Found these that need to be replaced, too
