I have a 1995 Lexus sc400 with 220,000 miles and I just replaced the timing belt water pump spark plugs and wires along with distributers and rotors now my car runs perfect except when I start it, it starts pouring out white smoke but all my gaskets are good and the car runs very strong with no hesitation so can anyone help me as to why it's smoking when I start it

 

Do you have any leaks? Such as power steering?

 

Yes I just replaced the powersteering pump because when I bought the car it didn't have power steering so I just fixed it and I replaced one of the hoses that was very brittle and hard however it does still leak but I really couldn't see that leaking causeing my car to smoke when I start it because after I start it, the car stops smoking after 15 seconds and I can't find any other problems

 

When mine had white smoke it was power steering air control valve. Got pic from another thread hope it helps.
