Hey folks, doing a head swap and my new valve covers don't have a fill neck with a nipple for the vent hose. Should I look for a cap with a hose or would I be fine deleting it? Doesn't the PCV take care of venting?
The PCV valve is where it goes out of the crank case, you need a vent for fresh air to come in. It doesn't have to be a hose, you can use a breather cap.
Does that have a breather element in it, or is it just a baffle? If there is no breather filter inside of it, that nipple has to be connected with a hose back to the intake.
It's baffled and I ran 1/2" heater hose from it to the nipple on the intake, still a closed system. It actually looks great with classic chrome valve covers
