"The engine has a slight amount of blowby and it comes out the breather on the passenger side. I want to plug it up but keep the breather look"

Not to pick nits, but....

The PCV is the best answer, only if you are trying to maintain the period look with the valve covers and breathers would I consider omiting the PCV. But you still need to vent the gases. Only way you are going to stop the fumes is with a PCV.

Maybe fit a PCV valve into the breather then add a hose to vent gases to the intake.

I'm confused? Why not just install the 67 vette filler tube as I stated earlier, that has the pcv installed in it. You can leave the breathers as they are. Then the engine will pull fresh air into the breathers and suck that air along with any oil fumes through the pcv valve.

That would be my choice with the '67 Vette fill tube if I decide to do some changes. The next problem would be finding one of those tubes without costing an arm and a leg. I want the old nostalgia look in my '49 Merc chopped sled.

I found Corvette Central sells reproduction Oil Fill Tube, Cap and Threaded PCV Valves for '66-67 Corvette. Should be able to do the whole changeover for less than $100.00.

How do you get the old oil tube out after many years of being in the manifold?

Do you put some type of sealer on the new tube and just tap it in with a block of wood and hammer?

Where does the hose go?

Never done it before so I have a lot of questions before attempting. Thanks in advance~~~Ron

If you have a Holley carb it has a dedicated PCV Port, as shown here:


To remove the old filler tube I used a slip joint wrench with a piece of inner tube rubber wrapped around the filler neck. Get the wrench as close to the manifold as possible.

Or you could use a strap wrench if you own one, I don't.

I put some Red RTV on the new filler neck before I tapped it into place. The new neck can be installed by placing a scrap piece of wood across the top of the neck and tapping it into place with a ball peen hammer. Just be sure to orient the PCV valve in the right direction before installing the tube.

Thank you for the removal and installation tips. I have a new Quadrajet from Jegs. I'll have to look and see if there is a place for the PCV Valve hose.

I found a couple of pictures of the Quadrajet I put on my 327. Can a Quad man tell me where the PCV hose plugs in or not.

Thanks

Just found this oil filler cap with PCV hose hookup on eBay. This ought to work with my old filler tube, couple pieces of PCV Hose and a PCV for a 327 Chev. I could do the whole thing for about $20.00.

Please look at my earlier post with the pictures of my Quadrajet Carb and tell me if there is a place to plug in the PCV Hose.

I think it will work......Any comments or suggestions?

you can use a "t" fitting in the manifold where your power brakes draw vacuum.You van also put a restrictor inline if required

I found where you plug in the PCV on the front of the carb at the bottom (same size as PCV Hose).

Couple of questions:

1. Look at the PCV Valve and it appears to have two different size hoses. I'm assuming this is a one way valve and the smaller end would go towards the breather (picture enclosed). Use a short hose to the PCV and then a larger hose from the other end of the PCV to the Carb base.

2. Should I leave the breathers in the valve covers blocked off? I took it out and drove it 40 miles stop and go with the breathers blocked off and it cut down on the fumes inside the car by 90%. Still get a whiff once in awhile sitting at a red light. I pulled off the oil filler tube breather cap and could see a very small amount of smoke.

Appreciate all feedback.

I did extensive research on the Standard Ignition #V112 PCV Valve (Mfg number PCV valve for 327 Chevrolet) and found out it has 3/8" barb and a 1/2" barb with the flow from 1/2" to 3/8". This won't work with the Mr. Gasket #2063 Breather Cap which has a 3/8" barb. If you were to install it with the proper hoses, the flow would be going the wrong way.

Anyone have any suggestions? Thanks

This part fits GEO, Issu and Storm 4-Cylinders. Won't work on a 327 V-8 Chevrolet.

Thanks for your input.

The easiest solution is to connect the pcv to the rear of the block where the road draft tube is located, behind the distributor, I have done this a dozen times. You leave the stock open breather alone in the filler tube, and run a hose type pcv to the rear of the carb, or screw in type- screwed into the vacuum port in the rear base of the quadrajet! The v112 valve is made to run from the road draft breather tube to the pcv port in the carb on a 327 Chevy!
