1980 Fiat X-1/9 Base 4 Cyl 1.5L


My rebuilt head engine runs but alot of gray smoke comes out from the exhaust

There are no leaks and good oil pressure. However a lot of gray smoke comes out from the exhaust. I have run the car for 10 minutes only. Should I hope it will go away or there is something wrong?

It may be related to moisture inside the engine that must be burned off, or if continual smoke is noted - then it may be related to an improper head gasket sealing, warped head or engine block. Check the cylinder compression to see if there is any signs of leakdown / improper seal in one of the cylinders.
