coolant loss during warm up

[cbccar]

1986 nissan king cab with z24 losing coolant during warm up period.cylinder head and gasket have been replaced due to leakage at #3 and #4 cylinders. has anyone experienced a cracked coolant passage in the intake manifold ?

Is the motor pulling coolant into the combustion chambers?

yes,it appears to have been pulling the coolant into # 3 and #4 after the first cylinder head gasket was installed since the color of the exhaust valves when i took the cylinder head off for a head replacement the valves on 3 and 4 had a orange tinge to them.the engine emits white smoke after about 2 miles of driving and after it warms up,white smoke no longer appears.i really dont think my original cylinder head has an internal crack since the condition still prevails.im thinking an internal crack in the intake manifold is possible. i used dye check on the deck and wall surface of 3 and 4 and no cracks are evident.what are your thoughts ?

Could be a crack in the head also. Get the head pressure tested.
