A week ago I did some lapping day sessions at HPR. Stock PCV plate.
With very firm braking to corner entry, the engine oil would overwhelm the PCV system, enter the combustion chambers, and create a huge cloud of smoke.
I could make this happen at will.
I could also pretty much keep it from happening by not braking quite as firmly; which I had to do because I had only so much extra engine oil on hand.
Installed the VWR Oil Catch system and went back out today.
No matter how firmly I braked, there was no smoke.
Very pleased, to say the least.
For the vast majority of drivers, the stock PCV setup works well.
But if you track the car, and brake as firmly for as short of a period of time as you can before turn-in, the VWR kit sure seems to solve the oil surge/consumption problem.
