smoking only at startup

okay only when i start it up for the first time of the dayi have white smoke comming out... it clears up after i get on the road. my hypothesis is coolant seals or something like that... also my car uses water like gasoline.. i may have a leak in the hose nearest the oil pressure sender but it shouldnt be leaking that profusely...well i just wanted to know what may be causing this smoking and why it only happens once a day..
thanks
jack

The seal between combustion gasses & water jacket is a rubber O-ring in a groove all the way around the aluminum housing.
If it leaks you get coolant in the combustion chamber, just like a blown head gasket in a piston engine.
I have had this happen, and was able to patch it with radiator stop leak.
I caught it early, before there was too much erosion of the O-ring.
The short version:
Hard to start, catches & sputters, blows white smoke, then clears up & runs OK.
To fix:
Good coolant flush, add half the stop leak, idle warm up to full temp, shut off & cool down cold, (repeat)
Do a search under "block weld".
Many have had good luck with that product & there is a good write up on the forum using it.
