What are you doing about crank case ventilation This crankcase ventilation thing has been giving me fits. I had what I thought was the ultimate solution (an electric vacuum pump) but it took a puke after only a few hours of operation.
What are you guys running?

Also, stock PCV means no ventilation under boost, right?

Thanks
*edit* i forgot my own set up! lol
now i remember that i have the valvecovers sealed completely, the intake hole and throttlebody sealed and just a one vent out of an ls6 valley cover to catch can. .. yea that sounds better

I have 99-02 valve covers, and have the covers looped in back and I have an outlet hose on the front of the passenger cover that vents to open air.
I probably need that for each cover seperately.
I have a 4/6/8 caddy elec evac setup but I have not installed it and it might not pull enough. How much is needed?

two breathers one on each cover and the hose off the passenger side going to a catch can, venting to open air. I also have the LS6 valley cover with the pcv set up for the LS6, should I also tie this line into the line going to the catch can, and cover up the pcv inlet on the intake manifold?

Valve covers tied together and vent lines. PCV line followed by check valve into intake manifold. Breather on passenger side valve cover. Also line going from valve cover to just behind air filter (Incon kit). I could get rid of the line from the valve cover to the air filter, not really doing much.

where are you guys getting your check valves?
white hawk, if you can keep oil out of it, it works good at moving air through the motor (ventilation, not vaccum)
i ran one connected to an rpm switch on my car for 4 months maybe, but i was pulling some oil through it and i think that's what eventually killed it.
.. fwiw i did not notice a decrease in mileage or oil color/contamination or performance by leaving it off... so i left it off.
