If you put an inline PCV valve in the loop, with the end that is supposed to go in the valve cover toward the red fitting, and the other end toward the blue fitting, the truck will run like it is supposed to. It is not only a check valve, it also throttles according to vacuum. It has a tapered needle and seat. Then you can do what you want with the valve cover fittings (breathers, or whatever).

Because the way I set it up in the above post, it will be the same as stock as far as airflow: the air enters the engine through the red fitting, into the valve cover, through the engine, out the other valve cover and PCV valve, into the blue fitting. The way I said just eliminates the engine from the circuit, and still allows the controlled vacuum leak that your engine needs to run normally.

That does not even seem possible just doing that? So now u have no pcv correct?

why would you want to make a vacum leak? and no you cant tune it out!! its gonna idle high cause its leaking by the thortlebody blade!!

I didn't think it was gona give me any gain either, I put the hose in there to make it runnable I was told by kenne bell if I just caped off the fittings it would screw my tune up being a MAF driven engine. I put the PCV back on for now it was throwing codes with the hose looped.

Why would you try and race a cobra with a stock truck and lie about beating him??? The PCV system is a constant controled vaccum leak, yes you can tune it out I talked to my tuner about it already.

Correct. Just like he wanted.
It is going to leak the same as a stock PCV system, minus the blowby that is in the crankcase. That is exactly how the stock PCV system works. It draws fresh air from the air filter side of the throttle, into the cranckase picking up the combustion gasses that blew-by the rings, out of the crankcase, throttled be the PCV valve, and into the intake manifold (Or vacuum side of the blower). There will be no tuning needed, because virtually the same amount of air is bypassing the throttle as in a stock setup.
