The prior owner did not just break bolts overtightening the valve cover. I found this as I was removing the silicone.
I wonder if I can find a 5V-EU. Would that pass CA smog?
[UPDATE: When my wife saw this discovery, shw shrugged and said “That happens. It is a project.” When I mentioned we could consider abandoning it for a project wothout such a problem, she was indignant that THIS ONE IS HER CAR, and goddamn it, we WILL save its life. For her, there is no other project.
