2,400 miles since then. Did a compression check, got 179 to 180 on all 4 left bank cylinders. Have the draft tube connected to the carb with a PCV in line. Car fires up right away and runs down the street in a very acceptable manner.
Again, only the left bank burns old when engine is warm.
Any thoughts,

The left bank is burning oil only after the engine is warm. Had the engine rebuilt last May 2018, it has maybe 2,400 miles since then.

Also,didn't see presence of oil burning.,forgot to mention that all 4 plugs were light coffee in color

I had a overhauled 289 that burned oil on the left bank, It turned out to be the compression rings turned alinging the ends of the rings, but it was very evident in the plugs. I assume you're seeing smoke. How much oil is it using? Are you sure its not water burning, that would be a whiter smoke.

Could be the valve stem seals were improperly installed on that side and one or two have shifted allowing oil down the stem . Pull the valve cover and look at the seals through the springs look to see if they have cracked or moved . If you plugs are clean and toasty most likely the oil is going down the valve stem and not making it into the combustion chamber . its just a guess

you could also have bad guides on that head.if valve geometry is of they can wear the guides in a hurry.i dont know how bad y blocks are for this.brand x is known for this.just a guess.

I’ll suggest performing a cranking compression test to insure you don’t have a piston ring or other cylinder related issue. It only takes one cylinder to create a problem. When doing the cranking compression test, all spark plugs need to be removed and the throttle needs to be blocked to the full open position. A leak down test will also get the job done.

.......Have the draft tube connected to the carb with a PCV in line.
When you say draft tube is hooked up to the PCV valve, are you referring to the oil fill tube in the valley cover or the road draft tube located at the lower left front of the block?

The DRAFT TUBE I'm reffering to is the tube that was connected to the valley cover and hung over the side of the engine to exhaust fumes from the crank case. Now, it is attached to the carb with a PCV inline.

Ted,
We did a compression test as you suggested. The range was 155 to 160 psi with 160 being at 80% for the average.
You also mentioned the draft tube. It is connected to a new Summit carb with a PCV in the middle of the rubber hose.
Let me refresh you on the situation. Engine rebuilt 2,400 miles ago. Oil burning out of left bank after car warms up and I take off from a red light or long idle. When the engine is warm and it is shut down for 10 or 16 minutes NO OIL out of left bank. The oil has had a chance to drain back into the oil pan.
What do you think ? Valve seals ?
Let me know, and again, thanks for your input.

Yes. If left off intentionally/unintentionally or if the rocker arm assembly was pressurized with no relief, the oil supply can pool in the head surface and overwhelm the valve seals. The left heads usually sees more supply.

I have been reading this thread and understand the oil tube is missing ,my question is will this missing part increase the volume of oil so much that it will flood the head ,so much it will cause the smoking , or is it possible the head gasket was not properly installed and with the valve cover on the oil is truly flooding the head. I watched the video on YouTube where the rockers are pressureized and the is a large amount of oil it properly drains away and there is no smoke from the engine. I am no expert by any means but the video on YouTube seems pretty definitive. Seems like large amount of oil is ok if it drains properly.

That tube was put there for a reason by ENGINEERING to regulate oil delivery volume. If the engine makes/holds good oil pressure/volume and the rocker arm assemblies are within spec, there is no need (IMO) to modify anything on a street engine.
If the engine has been modified, yes you would address the valve-train lubricating assemblies. Pressurizing the shaft will give you this but it would have to be regulated, i.e. via restrictions to ensure equal flow and relief.
It is much more involved other than removing/restricting flow of the tube(s). Those tubes also lubricate the timing set as well as the distributor drive.
If he found the head overflowing with return oil, the tubes must be used or it will overwhelm the valve seals regardless of the type of seals used.
The above is IMO and your mileage may vary.

Watching this video, it was noticed that he did the TEST on the right bank. I've read that the left bank is where the problem occurs with oil burning at IDLE. He didn't let the engine idle and then rev it up.
Our problem was a blue puff of smoke at red lights when the car was at idle for as long as the light was red. We all know there are short red lights and long ones. we'd leave the red light and for a few seconds there is a puff of blue smoke out of the LEFT BANK.
We'd shut the car off for 25 minutes and start it up................NO SMOKE !!!
After we noticed that the rocker arm oil return tube was missing, this explained the puff of blue smoke from the LEFT BANK and none from the right after idling for a few minutes.
Hopefully this problem will disappear and a new challenge will pop up.

Many run pressurized rockers, without the overflow tubes and without this problem on both banks. If backed up oil flow is the problem, then reinstallation of the overflow tubes may take care of the issue. But the root problem may be that the drain holes have become blocked, maybe by crud, maybe by a chunk of valve cover gasket.
If the tube is missing, do you have some sort of plug in the rocker stand? The tube also helps to locate the shaft within the stands so something should be in place to serve that purpose if the tube is missing.

To my knowledge, there is no plug in the rocker arm.
Last time I had the valve cover off and had the engine running, all I noticed was the rapid build
up of oil a the bottom of the head. The oil started to run over the lip of the head very quickly.
At this time, I was not aware of the return tube(s) were missing until I was a picture of a head with
the return tube in the working position.
That is when I put 2 + 2 together and came to the conclusion that the puff of blue smoke was
caused by the absence of the return tube.

This is a recently fresh re-build, correct? Did the re-builder ever say why he left the tube(s) off?
If fresh, the drain hols should be clear. A rifle brush will confirm if plugged by trash.
The practice of pressuring the shafts is practical. The video did not show how this procedure was performed, only the result. The flow has to be regulated and that will require a volume release IMO. Those tubes direct unspent oil to the lifter valley, not the bottom drain holes. Without the tubes, any overflow will go to the bottom drain holes. All has to be balanced.

When the car was purchased back in August 2016, we were told that the engine was rebuilt and the car sat in storage for more that eight years and had only 488 miles on a rebuild. The previous owner was an old GMC Dealer in Central Michigan. The car was restored as close as possible to stock. It had a stock distributor withe a Pertronic set up and a modern 4 barrel carb.
The engine was not a stock M code 292, it was a 312 with ECZ stamped all over and bored out 0,090 with aluminum pistons.
After driving it for less than a year, three lifters snapped or broke a part and chewed up the cam. put a nice hole in the valley cover (this made me mad and sad).
We pulled the the engine out and took it to be repaired. While talking to the person who repaired it, I pointed out the missing oil tubes and he said that there were no tubes on the engine when we brought it to him. He put it back together not knowing it need those tubes.
I'm guessing that the people in Michigan who original rebuilt the engine failed to install the return tubes.
I feel once we put the oil return tubes back on the engine, the puffs of blue smoke will become ancient history..........Update to follow.

The Tubes do not control the amount of Oil coming out but they do direct the Oil to the return Holes in the Head. As mentioned they also locate the Rocker Shaft so it does not turn blocking of oil into the Shaft.

I don't think adding the tube will change the amount of oil coming to the head, just redirecting it. Also, if you are seeing smoke on the left side only, you have oil coming out an exhaust guide on only one or two exhaust valves in one plane. If the valve cover was filling up with a significant amount of oil, you would have smoke on both sides instead on only one side. Sounds like you have oil being pushed out the exhaust guides and burning in the exhaust manifold and tail pipe until the engine gets hot enough to burn it off, and more going in on deceleration when the engine speed is lower and temp is lower. A simple check that is not so simple is to remove the exhaust manifold and see if there is a stream of oil residue coming from one or more exhaust valve guides. If the spark plugs are clean, the rings are good, if there is oil in the exhaust port and manifold, the exhaust guides are bad. Joe-JDC

You could also pull the valve cover and look through the valve stem springs , you may see a seal that shifted or moved out of place or has possibly cracked allowing the oil to pass what you describe is most of the time a bad exhaust valve seal just try touching the seal though the seal with a thin wire it should be fairly tight in place if it spins its your problem. I know you have drain tubes on the way, maybe you want to take a look at the seals while you are waiting for the tubes to arrive. You said the car sat for 8 years maybe the seals are hard. The engine was repaired after the lifters broke but were the heads rebuilt or resealed . I am just trying to help

It has to be the fact that too much oil is flowing out of the rocker arm where the return tube should be.
When the engine was gone through, the builder must have modified the oil delivery to the rocker arms, increasing volume. For whatever reason, the tube(s) were left off. Most likely as a result of reading all of the theories of pressurizing the rocker shafts.
The practice is valid but the flow rate has to be determined and allowed for.

No tube on either bank.
Apparently when the engine was worked on 10 years ago, they didn't put the tubes on either bank.
The car arrived at my address back in August 2016. I drove it for a short time and then had a big time failure...........three lifters broke and all hell broke loose. The car was in a repair shop for all most six months. I got it back in July of 2018 and didn't notice the smoke until my brother, who was following me to Cruise In at the local Quaker Steak and Ale, pointed out the blue smoke. And, I don't drive the car all that often so I didn't notice the puffs of blue smoke.
According to some of the members of "Y-Blocks Forever", the left bank will allow oil to seep into the cylinder head at a greater rate than the right bank. Could be because the oil pump is of the left side.
Anyhow, Carl, one of the members of the Forever Club has been good enough to send me the tubes. After they are installed, I give an update about the problem.
Tim in Florida

|
By charliemccraney - 5 Years Ago

The rate of seepage into the head should be 0 on either side not greater on one side than the other. Why would the left side be more likely? The pump has nothing to do with it since both heads get their oil from a cam journal with each being approximately equally as far away from the pump as the other in terms of the oil passages.
The passenger's side tends to loose oil flow sooner since the cam tends to wear into that side of the bearing. When this happens, there could appear to be more flow to the driver's side but what has really happened is that crud and/or wear has filled / closed the passage, diminishing or preventing flow all together to the passenger's side..

You are correct, the oil pump has nothing to do with oil to either bank, oil comes from the cam journal ( I'm a half ass shade tree mechanic....my sons call me a FAKE MECHANIC)

If you didn't get oil to the rockers during the priming operation, then you've got an issue anywhere from the center cam bearing up to the rocker arm shafts. Head gaskets can go either way to get oil up to the shafts so you should be good there. Soft cam bearings and camshafts with an inadequate groove depth are at the top of the list for rocker arms not oiling on a fresh engine build. Ted Eaton. Tedd, Aug 27, 2017
Oil delivery has to be verified before final assembly. The system was an engineering mistake, pure and simple.
ADDITIONAL INFO -
When there is a cam bearing issue, the right bank stops oiling first. In all instances, the 3 holes in the center bearing are still aligned with their respective holes. Have never figured out the mechanics of why that happens but it's consistent in that regard; right bank simply stops oiling first. Those cam bearing issues have typically happened within the first few hundred miles of the engine being rebuilt and the cam bearings being replaced. As mentioned above, I've never seen either an oem or aftermarket cam bearing spin in a Y.
The original (oem) FoMoCo bearings were much harder than the Durabond and Sealed Power bearings we get today. Several fixes are around for that cam bearing issue. Fix 1: Groove the center camshaft journal deeper, Fix 2: Install cam bearings with a outside groove on the center bearing (Schumann sells these), Fix 3: Machine a groove in the center cam hole of the block that allows the 3 holes to be interconnected (That's my fix!). If you end up with a surplus of oil to the top end, it's easily rectified by putting a drilled orifice in the bottoms of the second from the right rocker arm pedestals. Ted Eaton.

I have been working on Y Block Fords for over 40 years, I have never had a oiling problem, most problems I see are poor maintenance compounded with thick oil and aftermarket camshafts
(shallow grove), I also see head gasket trouble (blue gaskets) leaking oil into the cylinder from the transfer slot, and water stains on the side of the block, I don't think the lack of over flow tubes will do anything. The engine here is a 10,000 mile rebuild out of a 57 Thunderbird (head gasket problems)

The left cylinder head is flooding and there is no need for the tubes?
The FE had an modified/updated design and it too was not perfect. The FYB tubes has other usage other than bleeding off excessive supply.
The main reason(s) for the FYB oiling/sludge problem(s) (other than poor design) was non-detergent paraffin based oils of the period, lack of maintenance and poor crankcase ventilation.
The main problem here is that no one knows what was done as to upper oil supply and why the tubes were left off.
I think when the Y was on the drawing board, Henry happened to walk by and mentioned that it was to be an OHV engine and not a Flathead. The Rube Goldberg setup reflects this.

Hoosier Hurricane (2/9/2019)
Must have been Henry's ghost that walked by the drawing board. He died in '47. I doubt the Y was on the board that early.
I read somewhere, and can't remember where, that the Y-block was in development post war and was supposed to be ready for the '49 model year. For some reason, probably financial as Ford was cash-strapped at the time, it was shuffled to the back burner.

left head flooded as oil went strait up and flooded the cylinders at the end,bled off enough volume so right bank got less.
re fes owned 10 of them 332,352,361 edsel 360 trucks 390,406 428. never had top end issues.
early ys truck and lincoln had diferent source of oil for rockers and had no issues with to much oil. my present 292 has tubes removed and pluged drrain
holes both sides. with covers off lots of oil going to the correct places,push rods rockers valve train,lower drain to valley at each end of heads easly drains excess oil to timing chain and dist. gears. i have no blue smoke,no excess oil consumption. have not had to re set valves since rebuild. this is my4th y block in 5year period.2 customers, my 57 ranchero,existing 49merc f43 truck with 292 4v all have drain tubes blocked. have some experience with ford engines.also some strong opinions, right or wrong ,but some history. To date have not had a cam isue or il consumption.

The FYB was due for intro in the 1953 model run but was delayed a year due to material shortages as a result of Korea.

You be a luck Y Guy.
The rockers were pressurized and this caused major flooding of oil at the bottom of the head and at idle, puffs of blue smoke when the car started to move forward.
An Allen wrench was used to remove the screw in the passage way and the tube(s) were installed.
No more flooding. Even with the valve cover off, oil doesn't run over the bottom of the head and when moving forward from and idle, no puffs of the blue sh!t.
