My catch can routing ok?
I'm going to order a saikou michi catch split dc3 and do the last setup that you are suggesting for turbo applications. Is the only way to order them is through there site or is there a sponsor on here that sells them?
I'm curious why people use vented catch cans or put a breather on the valve cover. That opens the system. It either needs to be completely closed or completely opened with nothing going to the intake, otherwise the crankcase is pressurized.
Lot of good info in here. Thanks again for your time!

If you do NOT have a filtered fresh air source to flush out the caustic combustion byproducts, unburnt fuel, and moisture you will sustain internal damage over time as every time you shut-down and the engine cools all these flashed off harmful vapors will recondense back into the crankcase.
On a race only engine the oil is changed after every few races so it is not an issue, and we generally use a crank driven vacume pump and a vac relief valve. These engines are torn down & rebuilt every season also. A street motor MUST have filtered fresh air pulled through the crankcase to perform all the functions of a proper PCV system.

System is never closed....OEM it pulls filtered air from the main air filter through the throttle body, so all your doing is changing it so no oil enters the intake due to reversion pulse. Look at the stock routing carefully and it is easy to understand it.
If you plug off the stock source of filtered fresh make up air there is NO flushing of the crankcase. But you can run yours anyway you choose, just so someone uninformed does not follow it and end up with damage over time.
Sent you a pm.. can you please explain a few things for me??

so if i have a valley cover with a port. i dont need ports in my valve covers? and what do i do if i have a twin turbo. and even thought i have a turbo set up can i get clean air from my intake manifold?
thanks
thanks
You can put the fresh air hose in front of either turbo, doesn't matter. The intake manifold connection is for the dirty side.
sorry it is more that i want to make sure it is perfect. you said i can put it to eith turbo. well can i go to the manifold? or what is the importance of before the turbo? also once it get pressure before the turbo wont it suck air out of the clean side?
