The Ford 5.0 used steel bars between the bolts and the pan flange, torqued in sequence they applied pressure quite evenly. I feel like nickel and dime savings have sent many functional ideas to the scrap bin of history.
Similarly, it wasn’t uncommon for engines of just a couple decades ago to have cast-in grooves for extruded rubber seals & o-rings that only needed a dab of RTV at junctions. Of course simplifying castings won out favoring RTV everywhere, since it saved pennies.
With the fiasco of the first gen recall killing engines, I’m still confused why an anaerobic sealant wasn’t adapted in place of RTV. The entire clogged pickup and plugged oil passage issue would cease to exist.
