Like threw a crack? Intake or Exhaust manifold? If its a external crack in the intake then you need a new intake manifold. If its the exhaust manifold then it has to be leaking from the head into the cylinder or from an internal leak from intake manifold. Is there also coolant in the oil pan or mixed in with the oil in crankcase? Depends on how bad it is, can keep it from running and if it does run the longer it has been the more damage occurs until it does not run at all or runs bad. Many symptoms can occur, and many or those symptoms can occur together or absent from one another. From running hot to exhaust in the cooling system, They can leak inside the motor or outside the motor or into the exhaust or into the crankcase threw the cylinder walls or from the heads to the crankcase threw bad ring set or from the oil galleries, At first it may leak into a cylinder and get passed out the exhaust as steam., I fcoolant is in the oil pan then your bearings on the crank/rods are being worn away faster than you can think on it. So it all makes a difference where its leaking and how long its been leaking.

Usually blows smoke from exhaust and will over heat because of loss of engine coolant. Will eventually overheat and cause damage to engine parts.
