Only bearing clearances will cause the big end knock.
The upside down oil filter on our engines certainly doesnt help.
The oil smoke is a secondary issue to the knock.
Could be guides, rings or cracked piston.
Compression testing might find the bad cylinder, but then
again the plugs should tell the story too.
