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.

That filter performs the same function as the catch can does. All of the by products that would be left would still be there even with the filter, that's not a convincing reason to use a breather; opening the pcv system which is supposed to be closed

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.

Thanks so much for the informative posts. Just sent an e-mail to Mr. Michi to get a dual catch can setup. This is what I've always thought was needed for these cars.

Thanks

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

Diagram from above:



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?

Do you not know how to read? If you return it to the manifold then it will pressurize the crankcase under boost.

So i have a Revextreem for my valey cover, what one should i get to go from my valvecover to T/B? Preferable a small one.

can the air pump be programmed to run when the engine is running and serve as a vacum pump in the pcv system ?

but where it is suppose to be getting clean air, will start sucking air on boost

The diagram is based on the LS1 PCV configuration, but the concept is the same.

aaron,
i will try this. and let you know. thanks,

but if i have a ls2/ls3 valley cover with the port in it. i dont need to get valve covers with back ports? i can buy ones with out?

thanks
