I know I could get a lot of different opinions but here goes anyway.
What sealants/Loctite/other do folks use on:-
Case halves
Cylinder studs
Oil gallery plugs
Small case studs (oil cooler etc)
Cylinder head nuts/washers
Cylinder to case (with spacers)

Cheers.........Wayne

Loctite 518 for the case halve as it does not stop the bearing crush,
Loctite grey on the barrels
Loctite 577 pipe thread sealant for the plugs and fittings

Make certain all surfaces are cleaned with a good solvent like a lacquer thinners.
