My bmw e90 320i always loosing the coolant, but I could
not see any leaking on the floor.
I have noticed the car very hard to start 5 long crank after
the car have sitting for few hours,and also i have noticed
white smoke coming out from the tail pipe when I start the car.
But after the car used for a drive the white smoke gone.
Is this could be the blown head gasket ?
Thanks

White smoke is likely coolant. I would pressure test the cooling system. If the system will not hold pressure and there are no external leaks the head gasket may be faulty.
