Chasing an oil leak that appeared to be coming from the valve covers. Aluminum valve covers, fel pro gaskets, arp studs. This was a serious leak, changed valve cover gaskets still leaking. Changed intake gaskets and resealed with RTV the china wall. Still puking oil from what appeared to be the top end. I was about to the point of pulling the engine. I had eliminated any top end leak areas.
I pulled exhaust manifold and located the source of the leak. The block had provisions for right hand dipstick and left hand dipstick, one side should be plugged. I had no plug. It was blowing oil up making it appear to be coming from the top end. Stuck a bolt with some RTV in the hole and leak problem solved.
The kicker is I searched several forums and not one mentioned this as a possible cause for the leak.
