So I have a new intake pan with a PCV hole in it. I have a PCV and I am running it up to the front hole on the intake manifold (my Teapot does NOT have a vacuum connection)
I blocked off the road draft hole. But I am still having oil coming out the fill. After the element becomes soaked the oil comes out and gets all over that side of the engine.
Any suggestions? It's a 292 with stock Holley 2 hole.

Did you remove/disable the original road draft unit on the LF of the engine?
Put a vacuum gauge on the dipstick tube and see whether there is any amount of vacuum in the crankcase while idling. You may have to go to a different valve. Also, any engine gasket/seal leaks causes loss of vacuum in the crankcase.

you can buy the proper spacer under your carb to hook up a pvc on a teapot.

I have not found one for my 2 Barrel, have a link?
But then again how different would that be as opposed to the opening right in front of the Carb in the intake manifold?

KULTULZ This is a 292 from a Pick Up and had a road tube out the back. It is closed off. It did not have the opening forward.

OK. Do you know by any chance the year of the engine or what year pickup it came out of?
It sounds like the PCV is inoperative or blow-by is overpowering the system. Is the PCV placed where the original road draft tube was?
Can you show a photo(s) of the install? Do you have a vacuum gauge? If the gauge shows a partial vacuum, you are on the right track. If it shows pressure, either inoperative or overpowered.

It's a Mummert valley pan the has the baffled grommet boss and a V8 PVC (I wish it was a 90 but it's straight) that he listed.
I don't know the year but I think it's from a very early 60s PU. The Intake is from god knows what but I put a fitting in that opening just forward of
the Carb for the PCV line.
I know from the manual the oil tube is supposed to be a "suck" not a "blow". No vacuum gauge but I can get one I guess.
The original had a road draft tube in the same place but someone ran a line from it right into where that threaded block is in the back of the intake you can just see in my picture.

OK. You need the gauge. It is a combination fuel pressure/vacuum gauge and is invaluable for something like this. One should be about twenty dollars (quality).
The vacuum source @ the manifold you have is fine. It is OEM style (verify once you get gauge - maybe something built a hive in there). Truthfully, at the carb spacer would be better but FORD only used that setup on the LT 292 4V setup.
You have to verify correct manifold vacuum and the setups ability to draw a partial vacuum in the crankcase first.
It's a MUMMERT cover? I will have to look at one (I was never able to afford $$$ speed parts) ... 
Get back.

"It's worse than speed parts, it's bling..."
HEY! I was young once too...
Now you need to louver the hood to show it off...
If your cover has this baffle, you are good to go -
When you pull the valve out while running, do you feel suction as you put your thumb over the valve?

I don't know about others on here, but I'm confused! Post states that the rear draft tube opening is closed ?..then the photo shows what appear to be a PCV valve in that position.. then an other hose going to a fitting connected to what?.. Like to help but I'm lost..

MUMMERT offers two styles of covers, the early road draft version (with the road draft on the LF engine lower skirt) and a style for later engines that actually had a road draft tube on top of the engine or PCV System.
The Y ran from 1954 to 1964 so there were several design/revision of CCV (Crankcase Ventilation)
Does this help?

I have a pcv setup like that on my truck. Change the pcv valve. I had issues and it was bad brand new out of the box. $3-4 for another one is cheap insurance. Otherwise you've got a lot of blowby.

Sorry. The road draft tube was removed and was sent right to the back of the intake. It was a PU engine but had an earlier style pan that I replaced with a new pan and PCV. The PCV now goes to the hole on the intake just before the carb. The connection in the back only seemed to feed 2 cylinders.
The rings must be seriously worn. Oil is coming from the oil fill all over the passenger side and the tail pipes smokes after acceleration. It goes through a quart after a couple hundred miles.
I disconnected the PCV and ran a heater hose for a draft tube to see if the smoking tail pipe remains unchanged.

Running the hose might tell you something. But the symptoms you describe, oil pumping out the oil fill and smoking is classic for a PCV valve stuck closed as 1960 stated above. I’ve seen cars with closed PCV systems (oil fill routed to the air cleaner) pour so much oil in the carb the engine loads up and quits.

Skyhunter: Don't know if this helps at all, but, your statement that " the rear of the manifold only appears to feed from two cylinders, is incorrect. That orfice should split inside & feed from 4 cylinders.. As others have indicated you may have a defective PCV valve & or a serious problem with engine internals. Need to check out those possbilities.

Just for discussion, describing Mummert's Valley covers as "bling" is pushing it. Quite often original valley covers from engines that were out of chassis or say from a salvage yard have distorted or damaged valley covers that may not seal properly. But, more importantly the rear vented model is designed to replace the side of block canister unit & permit use of a rear crankcase draft tube or better yet a baffled PVC setup.. That's hardly bling!

The vacuum source on the ECZ-B intake does draw from four runners, 7-8 and 3-4 but the main draw will be 7 and 8 runners because of it's (vacuum boss) positioning on 7-8 runners. It is not meant for a PCV vacuum source as the engine crankcase fumes will overload those cylinders and not be distributed equally among all cylinders.
Also, any oil leak (gasket/seal) in the engine assy will not only leak oil but will lessen the affect of the PCV System as the internal vacuum draw will be lessened through the valve/system with outside air and also possibly disturbing fuel mixture ratio.

Paul,
I was referring to the comment about not having money for "speed parts".
A good quality and serviceable truck valley pan from a PCV engine is functionally the same, so compared to that it would be.
Of course a distorted or damaged (same thing really) pan would not compare. One must always compare apples to apples.

You stated that you removed the pcv and ran a draft hose. Did you watch the end of the hose to see how much smoke comes out of the hose? Usually smoke after you decelerate is an indication of bad valve stem seals. You could also have bad valve guides. Have you had valve covers off and check to make sure oil drains for the heads are clear?
|

Valve stem seals are new. Passages are clear. Smokes at acceleration. But not every time.

You need to discover why the crankcase is pressurized, whether improper ventilation or blow-by.
Have you read the plugs?

On a side note. Where can one source a pack of these huge honking oil drain plug gaskets? This brass one has long since passed its days.
Every time I got to the parts store all they have is the wee one's for a car plug.

Try a good hardware store possibly in plumbing?
