Your engine has a severe HGF,

Your engine has a severe HGF, and knocking from the bottom end (under load) indicates collapsed main bearings.

You need to contact an engine remanufacturer who will either exchange the engine or refurb yours, Or find someone breaking one - I am in contact with someone who is doing this right now.

The Daihatsu Applause is allegedly an identical unit.

re: ENGINE NOISE

The white emulsion in your crankcase is water and the fact that your radiator expansion tank is bubbling and steam is issuing from the exhaust is an indication that you have either a blown head gasket, cracked cylinder head or cracked engine block, which is allowing water from the radiator of your engine to leak into the engine's oil galleries. The knock is due to the effect of water dilution of your engine oil. Do not attempt to run the engine in this state unless you plan on repairing SERIOUS engine damage. If you have stored the vehicle properly (i.e. with anti corrosion and anti freeze mix in the radiator) chances are its a blown head gasket. If not, the alloy cylinder head has probably corroded through in at least one place, which means pulling the head off the engine and either repairing the damage by TIG welding and resurfacing the head or replacing the cylinder head.
