Manifold?
are you thinking this is the source of your oil light on and lack of power? ect? i dont think a crack in the valve cover would cause that, its a metal part, no sensors ect.... have you checked your oil level? how far have you driven it total sense the valve cover job?
Edit: I'm dumb.
so did you jb weld the piece back on or did you end up welding the cover to the head?
I only drive it a total of 1 and a half miles. I think I might have connected a connection that wasn't connected.
Somehow I don't believe that is a stock VC bolt.
Glad you found the problem though.

I guess no engine swap?
Most people complain about working so far away and wish they worked closer. When in fact it's not that great for your vehicle to work closer as your liquids and oil don't reach their ideal temp. You can build up some gunk real quick!
