    Default Vitz 1999 - smoke issue after Head Valves change

    I have 1999 Vitz and had to change head valves.. 2 were faulty so mechanics replaced it and adjusted others. We did that yesterday and when we started the car, it is giving white smoke. Mechanic was saying it is steam and will adjust in a day but i am worries as initially it was too much but now it has reduced a bit. Is it normal?
    Some people are saying it is because some oil falls on piston and the smoke is because of that oil burning and it will settle down in a day. I drove my car for around 50kM and then checked the smoke of running car but it was not there but now when i parked it and restarted after a min.. the smoke is still there. It is white smoke and in higher quantity then normal.
    Please advise???

    Angry

    so the USTAAD removed the head and ONLY replaced 2 valves ?? I seriously doubt if he replaced the head gaskit, washed & clean the head from both sides. Did he used a torque wrench to redo the head to engine block ?

    Now please do not tell me that he replaced the 2 valves without removing head ... if thats' been said & done Please !! pull the plug of your pc NOW

    first check is it oil burning smoke or steam ?
    check the plugs if there is any trace of oil ?

    Some Oil Fall On Piston And That Oil Keep Burning For A WHOLE Day...Woowww...Ask him to get us some of that oil...who keep burning for whole day...might save GLOBAL Oil crisis For Good......!!

    Your Valve Seals Are Leaking And Surely He Didn't Replace Them....They Are LEaking Oil Into Combustion Chamber...

    You Will Face Massive White SMOKE When You Start Car Early In Morning....No or Less Smoke When Driven And As You Park And Start Again....Till Them Oil Will Leak into Chamber And Burn Again Causing White SMoke As Well As Fouling Your Plugs Also...

    very rightly put by @SER_GTR .. the symptoms are clearly of stem seals .. get them changed .. leakage from seals makes oil drip in chamber and overnight some quantity gathers up which gives excessive smoke .. less smoke or no smoke while driving means not much leakage so it could be a simple seating of seals issue .. they have a spring lock which grip valve at a certain cut maybe one of the seals has not seated properly

    ^In Seal Leak...A Very Small Amount Is Leaked In CHamber...So He Will Need To Wait For Oil Level To Drop If Leak Is Minor....

    This is a classic case of cylinder head valve seal leakage or even cylinder head valve guides being extremely loose and worn out.

    The massive smoke stopped after a day. But now i do have some smoke in the morning and it is more then what I used to have before this fixup of engine. Oil level is normal and has not decreased. At the same time pick of the car is fine.. i have not experienced any issues on that. According to machanic he changed 2 valves but i doubt it.. most probably he sent all valves to kharadia who just polished them and adjused them. Is this smoke activity ok.. or do you guys think oil is leaking into combustion?
