Question

What are you working on?

Do you not have a place for the valve or the inlet hose (closed system)?

trying to understand your situation... I'm assuming you have your PCV valve plugged into one of the valve covers, and the vacuum supply at the other end has no place to plug into the carburetor?

You just need vacuum, so install a tee into your full vacuum line and plumb it from there

To answer your question it would really be a help to know what your working on. Some (most) carbs have a port specifically designed to accept the line from the pcv valve. Check it out. On an edelbrock its right in the middle on the front. On some quadrajets its on the back. Not too sure about demons and holleys, but I'm sure someone here could help you out.

it's a holley, the new k&n filter has no place to put a hose.
do you just run the valve to a vaccum source? i figured to just block it.I thought vaccum would just make it idle bad (vaccum leak) please advise.thanks, mike

I think that you are mistaking what you PCV is. It plugs into the valve cover. A hose runs from it to the largest vacuum port of the carb (bottom of carb)...

I think the hose that you are thinking of is the air cleaner vent. You don't really need that.

You can eliminate the fresh air inlet hose (if that's what we are describing) by putting an open (filtered) oil filler cap on the opposite rocker cover. This will provide proper ventilation.

That's what I use on my 77. I had some trouble fitting it to the valve cover, yet another wonderful Mr Gasket product.
