A little white smoke on start-up is normal. Nasty smelling white smoke is not.

Black smoke should only occur during hard acceleration... if it occurs even at idle or low rpms, then you have a problem.

Have your pump and injectors calibrated, check the water separator and double check that your radiator isn't half-filled with mud.

sir parang hindi na normal ung white smoke on start-up kasi usok niya hindi na tolerable compare before so napansin ko na something wrong na talaga. medyo madumi na nga radiator ko sir anu po gawin ko anu dapat ko ilagay or dapat ko na pabaklas then palinis?
then balak ko nga din po magpa calibrate sana maayos.

I'd suggest doing a compression test. If there's oily gunk in the radiator, it's possible your headgasket's shot.

Kahit normal na medyo mausok ang 4JA1, hindi naman ganon at wala namang ganong usok ang Hilander mo dati diba? So hindi talaga tama yun. Unang una siguro subukan mo palitan ang mga langis at tubig, magpalinis ng injector nozzles (or replace if necessary), linisin yung air filter at siguro baradong barado na 'yon, and then linisin ang tailpipe. Kung hindi malubha ang kondisyon ng makina mo, siguro pwede na to.

Read this TS; Diesel Smoke tells YOU a Story…

Kung nakakaranas ka na nang overheat, cylinder head problem na.

Boss nornally white smoke is associated with water mixing into the engine oil going to your piston. Maybe you have cracked cylinder head gasket( consider your mileage, 100km upwards dapat check cylinder head for warp or crack and check c.h. Gasket) check your radiator and coolant kung nagbabawas ng tubig . Peace=)
