Default PCV valve

Can I take my PCV valve off and just put a regular breather cap on? Going to Autozone to order my ignition swap parts and a few extra things and thought about this.

Yes, just make sure your valve covers have the baffle (metal piece under the vc breather opening) installed or you will get oil spray on your valve covers. If the baffle is not installed, you can install one or use the grommet designed to keep oil out of the breather. The baffle is the best solution as I've found the grommets to still allow oil through.

question,

i think my 302 was all hooked up wrong, the driver side pcv valve was hooked up to the spacer under the carb when I think it should have been hoooked up to the air filter and the passenger side pcv valve just had a hose on it that was loose. that one had a vaccum pull and was just loose.

what is the correct setup????

I may be wrong, but the one to the spacer is fine. As for the loose hose, take that junk off, and put an oil cap on there.

Correct me If I am wrong.

That is how my dad has his 350 setup in his truck, except we have TBI on it.

or should the driver side have a breather on it and the passenger get connected to the manifold?

I couldn't imagine that making a difference. Unless you are going for originality, in which case the space has to go and blah blah blah.

shouldnt the vaccum hose on the passenger side be the one connected to the manifold?

The best way to do it is to hook the pcv up to the d-side and the breather to the d-side. This keeps oil slosh from being picked up by the pcv valve while you accelerate.

And BA, you don't want to remove your PCV system. There's absolutely no reason to, and there are several not to, most important of which is sucking all of those corrosive gases out of your crankcase.

You mean the PCV on the driver side and the breather on the passenger side?

I agree with Starfury in that in all but a few radical cases, a PCV system is a good thing and a functional thing.
