Carl Lynn sent me some pics of some rocker arm pedestal caps he found on a Y engine he was tearing down.  Anyone seen these before or have any idea what their intended purpose was?

I've seen several on engines of unknown origin(truck/car?). I always thought they were a factory item. Possibly an early attempt to block the oil returns to pressurize the rocker shafts? Chuck in NH

Y's guys rule!
Looking for McCullouch VS57 brackets and parts. Also looking for 28 Chrysler series 72 parts. And early Hemi parts.

I've got a pair on my 57. I picked up some 1.5 rocker assys. off ebay. When they arrived they had those caps on the end pedestals where the oil return lines went. I assumed it was to make the rocker shafts pressurized. Seem to work fine I have plenty of oil topside.

That is part of a rocker arm oiling system. In the picture the cap is on the opposite end to the return tube.



The picture shows two bolts in the stand there should only be one as the other bolt is the valve cover holding stud.



One removes the valve cover stud and replaces it with a supplied partially hollow stud (only drilled to the horizontal hole). The stud has a hole drilled horizontally to supply oil to the slot shown in the picture and then connects to a thin copper line usually run to a port on the oil gallery or the sender unit for oil supply.

Hello Marv! This is part of an aftermarket oil supply kit?

  

I have found these on at least two y blocks that did not have the external oiling system installed. They were both early models pre 57.  I don't remember the slots, seems as if they were solid. I'll dig through the stash and see if they look like these.

I have a couple made from aluminum stock, these appear to be cast iron.  They are from an aftermarket overhead oiler kit as described above.  There would only be one per side, not all 8 stands.

The engine these were found on was supposed to be a 63 ford truck motor but after cleaning off the dirt and grease it turned out to be a ECG block.Someone had taken off the truck parts from another engine and used them on this block,probably the origional 292 had blown and they had the 272.It had one ECZ G  head and one ECL A head, both rockers were 1.54 though.The alum. pedestal caps were on the ends where the overflow tubers are normally and the valve cover studs were solid.The piston were stuck so solid that the block and crank are going to be scrapped.I t also had a alternator instead of a generator,the alternator bracket looked factory made but someone might have fabricated them.   Carl Lynn   

Scrapped because you can't get it apart?  If you just can't get it apart, let someone have it.  It will come apart.  You gotta be patient.  When patience runs out, you can bust the pistons and then it's easy to get apart.

The engine I'm running right now was frozen solid.  I sacrificed a few pistons after a month of patience and it was in pretty good shape.

I got 'em.  They came as part of a rebuild in the early 90's from a machine shop that did a lot of work on y-blocks.  I always assumed that they were to keep the rockers pressurized....not sure if they are OE parts or not.  Mine look exactly like the pics...
