what happens if I remove mine pvc valve? how many vents I must leave overhead?

 

You will need a catchcan to replace the PCV.

does removing the pcv valve and getting rid of most of the emission parts do alot for the car or no?

 

Back in the early 70's when emission laws started to have teeth, engines suddenly had half their former horsepower and sometimes had so many vacuum hoses the engines disappeared beneath them. So, what to do about this terrible situation? Well, the answer seemed simple enough, just tear off those hoses.

That was hardly enough, the engines had been changed in more basic ways – smaller valves, smaller cams, lower compression ratios and restrictive catalyzed exhausts. But, still the myth lives on – the road to more horsepower is through removing emission equipment and vacuum hoses.

 

You NEED to keep the PCV if you're going to still recirc it to the intake manifold.

If you're going to run both the breather and PCV to a vented can, then that's fine.

Using the vaccum of the intake and intake maniofld is nice to help "pull" the oil vapors out. You just need to use a closed catch can (one with a breather on top) and make sure it's baffled.

 

A friend of mine uses an air line vapor remover between the PCV and intake manifold. That works well.

 

True. I used one of these before. I ended up buying a bigger, real baffled catch can because I have to empty the small air line vapor remover so often. I still use a simple clean fuel filter for the breather side.
