will this swirl port work a treat on I5?

[popdemonic]

i have digged up a lot of infos about how to stop the blow by coming through the intake tracts.i have a Provent 200 oil separator on my car but it seems it couldn't handle the blow by on my motor.i believe my motor is healthy enough.i have had the excessive amount of the excessive blow by on old engine too.the motor has 165psi on compression that's why i do believe the problem is the stock CCV system is poor on running
30psi of boost.i didn't track the car.last week i had some funs with the RS5,TTS,GTi.
when i was back home,i pulled out the dipstick and was sursprised when i found i lost
0.5L of motor oil after a spirited driving on street race .the motor oil splitted all over the oil separator due to the pressure relief valve on the top of the tank was working on its job. My plan is going to get some bigger breather hoses and going to drill another port on the valve cover and baffled under the valve cover.i did search locally and found this
swirl pot.there's a couple meshes in the middle of the tank to prevent the oil surged.will this work on the I5?

What sump baffle do you use?

^ This... That is the main question of how much oil would be forced in the breather. Well, of course also the powerlevel of the car will affect in that, and if you are doing a lot of drag launches.

I have stock windage tray.i didnt mod any baffle on the sump.i dont need it s necessary on my case since i didnt track the car.

Hi Thuppu,
my car has GT2871 on E85.the power level is 450HP on crank.
IIRC the stock CCV system can handle somewhere around RS2 spec.
my car is already above that.

Reading this, I remembered I had a pic on the computer, showing Martinssons crankcase breather

The main problem with the breathers on these cars is that all breather outlets are in the rear of the engine. A launch with a high power engine with stock sump will force a huge amount of oil in the breather hoses. Usually the problem isn't engine blow by.

I agree Thuppu after my observation i found it's not the oil fumes being pushed out
the CCV.it's the motor oil surged from the G-force when hard launched.again,
i just put a pretty fresh AAN engine on my car.surprisingly,it acted the same as my
old engine.the huge amount of motor oil being pushed out the left side of block CCV vent hole. i have a spared oil pan that i can weld the alu. plates with a hinges gate
inside the oil pan.labour time has begun again.

I also had a lot off oil in my catch tank after some hard launches and fast corners. Made a simple baffle and all is fine now.

i combine a baffle in the sump with a mann provent 200 and last time when i was tuning vems on the road with a 500hp setup i have totally no oil in the mann provent with hard acceleration

Thank Nick and V6quattro for the photos!any tips to do the baffles in the sump?i'm worrying about the clearance between the stock windage tray and crankshaft.Definitely i would need one on my car.

i'm worrying about the clearance between the stock windage tray and crankshaft.
why???

i have also a AAN engine with stock windagetray with a baffle in sump

good to know Nick.I will be doing the prototype on my spare oil pan tomorrow.
Thanks mate.

what's the best tools for cutting an Alu. sheet?
