Blow by for most around here is the residue left behind from a PCV system in the air intake box, it is residual oil from the vapors evacuated b y the PCV system. Yes just as you described!!! LMAO

Thats the symptom, the cause is worn out piston rings, allowing the pressure to blow by them and build up in the cranckcase. Hence the term.
