No power when it was running

Left hand headlight stays on even with the ignition off

The fuse box is worn out may on some loose contact to fuse slot, I want to change the the whole fuse box for new one where can I buy it

Smoke out of exhuast is white... but later when driving leaves a cloud of grey/blue smoke... can have moments when its fine,no loss in power or water... has lost a little oil.

Horrible rough idling No accelartion Lost of power Changed spark plugs Changed coils Changed intake manifold gaskets It then stalled while driving on highway Had it towed home Any suggestions greatly…
