Glad to hear your Problem solved. Can U solve mine? Major Snow Storm Today. Lucky U. 80???

  

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.

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.

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.

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.

this post has a life of its own.it should set some kind of record on here.

I was being facetious (Latin for a$$-hole)

The whole thing looks to me as - OH SH!AT! We forgot something....
