You need to repost that picture because we can't openit up bigger, but non the less if that valley is now fully sealed and was not before, then yes that is why your pushing oil and dip sticks out.
If that valley is now mostly sealed a header evac system will not work so you need to run a vacuum pump or drill and put vent tubes in there like they with BBC motors.
I am really questioning that builder and his thinking / guidance now after seeing this.
