This is very dangerous as it can ignite without a spark and cause detonation irregardless of the mapping on the car. On high boost cars its best practice to vent the breather away form the intake at all costs.

you are absoutly correct thats why you modify the breathing system so the oil is seperated from the vapour before it gets to the intake
