Blow by is the compression gasses that leak past the rings. All engines have a certain amount but it increases as the engine wears.

What is 'blow by'? Euan CHCH NZ >>Open the oil fill cap when running. If smoke pours out then your blow by probably has finally exceeded what the system can handle & crankcase pressure os pushing the oil out somewhere. This test does not work on some BMW's or Volvos as they ran positive crankcase pressure.
