Apparently our leased Transit 250 vans have had an issue with throwing rods (not mine), it's happened to 2 engines, both under 50K miles. Has anyone heard of any problems with these? The one in my '18 has always sounded like it has loose rod bearings since day one, I've been tempted to slip in a little of my LM MOS2 when the dealer puts in their weak sauce 5W20 (MC?).
