VB series Block bung set - included are:

the main gallery special (socket cap screw or allen type) flange plug & seal - fits in the timing cover, replaces 50041

the oil pump gallery taper plug to the correct size for drilled gallery (this gallery should be drilled out all the way to the pump & then finally drilled then tapped to 3/8" bsp as the gallery is too small), replaces 50040

the vertical oil gallery lower flange plug from sump area towards head, inc seal, replaces 50040

a revised oil feed plug / restrictor kit to the head, inc seal, replaces 50039

the oil pump jackshaft feed gallery flange plug, inc seal, replaces 50043

5 seals for cheese bolts, sump bung & rear gallery plug, replaces 50047

1 seal for Oil Pressure Relief Valve nut, replaces 50051, NOTE that this seal is thicker than the original so a packer may be required between the spring & the nut to return the oil pressure to its original value.

Special sealant - not that its needed !

As these are all flange fitting except the pump gallery plug, they don't rely on a good taper seal as does the std AML parts so you get better oil pressure (no loss of oil / oil pressure from the plugs !) & no internal leaks.into the crankcase / timing cover

A set is also available for the MkIII engine.
