'67 283 carb question

I was looking at my engine a few days ago and noticed this aprox 5/8 black hose from the back of my carb...'67, 283, 2 bl carb. It attaches at the back bottom, goes out passenger side, and then looped behind the engine. I decided to pull on the tube and it come out ...not attached to anything. Is this hose supposed to be attached to the trans? I had the trans worked on last year. Help! What is it for?

Arden,that should be attached to a PCV valve on the back of your carb,then routed to the vent tube set up that replaced old draft tubes on the block behind your distributor. This was the way it worked before the push in PVC valve that went into the valve cover starting in 68. 1967 and prior years used the push on vent/oil fill cap with this set up for engine breathing, 68 switched to a non vented screw on oil fill cap with the intake vent using a hose to the air cleaner,then the oil fill cap was located on the valve cover after that.

Sorry, not sure if I understand. This tube is connected to the base of the carb at the back. The connection is facing towards the passenger fender. Then the other end was tucked behind the engine as if it should be connected to the trans somehow.

Thanks

Arden, here is a picture of where the hose attaches.

Thanks so much! I looked at my engine again last night...Sunday April 9. Yep, that pvc plug is like your photo...no hose attached. The bums that rebuilt my engine couldn't hook that up! I really mad! I will hook up that hose soon.

What is this hose set-up for? What does it do?

That is the area where the old road draft tube went . If you plug up the end of the hose the crank case will not vent and pressure will build up in the block and evently the seals will push out on the back or front under the intake and a massive oil leak will appear .

Yes pressure inside the crankcase is bad, but I have never heard of it blowing out the intake gaskets . I not saying it could not happen, but my experience tells me it wrecks havoc on the crankshaft seals. Morley

Re: '67 283 carb question

Thanks so much. I sort of looked at it again yesterday...not your photo area...but top of the trans area. Looks like a pvc knob or something sticking out and the rubber hose looks long enough to reach it. But, me being a know-nothing, don't know what it would be for. I will see if my car is like your photo, but my hose would be too long. I think my hose is about double this one.

My trans is an automatic.
