As Ray says I use RTV and hard washers on all main bearing bolt nuts except the center inner...I use regular grade 8 nuts with loctite blue too. Engine oil will track up the main bolts.I found Vw aircooled engine case stud hard washers fit the A main bolt perfectly,hard washers give a positive surface for the nut seat,unlike ford grey iron..
