Good point Tankengine, then you have to worry about valve guides, camshaft bearings, cam chain (top) etc., then you have to worry about the tops of the gearbox seals, axle seals, diff seals and so on.
Since no more catering didn't tell us what vehicle or how long it's a piece of string, and maybe he was playing with us.
Up here in the dry local conditions I've started engines which have been idle for 40 years without any preservation - just a good squirt of WD40 in the plug hole and turn over on the stater to blow the residue out so oil does cling to the bores, but if water can get into the manifold the engine's seized.
Some manufacturers have long term (6 months +) storage procedures, but they are extensive and involve a lot of disassembly and coating with grease, so no more catering, if you do want to store a precious vehicle (not one you would be better off selling as advised above) you would be well advised to scour the web for some of the old instructions - usually British, and parfticularly where a vehicle was to be shipped by sea.
