I will explain the sys in detail in the AM. You can get everything ya need at the parts store for a few bucks.

 

I haven't seen or worked on a y block in a long time but as I remember those oiling kits came with 2 replacement rocker cover hold down studs which were drilled and threaded to accept not only the nut on the outside but also a
pipe thread fitting 1/8 I think to which the line attached. It may have been that we drilled thru the rocker arm shaft at that pedistal which the stud screwed into. I do know it was possible to flood the valve chamber if the returns were blocked. If I had one which did that I also put a restriction in the line to reduce the flow. About all I can recall.

I look forward to the info. Arctic Y and I appreciate all the help.

 

OK this is like a Murphy's law type of day. I only got a minut. Remove valve covers and you will see two little pipe coming of the rocker assembly. On mine one exits the rear and one forward. You want oil resistant hose that you have to force over these pipes. Tight as possible and still use fuel line clamps.
Locate the sending unit on the drivers side of block(low and to rear) . Remove and take with you to parts store if electric to make sure ya get the right size and thread. Standard pipe thread I am sure. Get a T fitting, and a nipple that will fit the hose. need a clamp there. Behind engine by dizzy(or where ever ya want) you will install a T or Y fitting to split the hose 3 ways. Three more clamps. One to T at sending unit With sending unit in one side and hose on other. Hook hoses To Y or T by dizzy and run one to each rocker tube. I uses 5/16 OD hose and drilled the valve covers just enough to force the hoses in As snug as I could so as not to leak. I put one in back and one in front because I was in a hurry and didn't want to figure out a way to run the forwed poited pipe's hose down the inside of cover to keep it cleaner looking. But ya can figure how to run them both through the back and hide them. ya just got to ensure they don't rub on the rockers or other moving parts in there. Last ya need a valve between the sending unit hose and the Y by dizzy so ya can regulate the presshure or you will probaly fill the covers even if the return holes ar free.

Hope this will help. Know that you can open up the stock oil passages if you are doing an over haul and with todays oil most likly not have to use this system. I Will use it on all dayly drivers. Or older engines that have had wax based oil used in them. But not on a fresh show engine that is only a Parade Queen.

 

Got it Arctic Y and just saved the instructions. Thanks for the help.

 

I am glad to help.

 

Artic Y,
You do realize that the drain pipes are there for a reason? One is for the oil to run onto the cam-distributor gear for lubrication, and the other is for cam thrust,timing chain, gears and fuel pump lubrication. With the drains blocked for valve train oiling the other components starve for oil. Rob Peter to pay Paul.

The overhead oilers that use the valve cover stud allows for all components to receive lube.

I don't see that. I have a set of covers with the tops cut out. my covers are about a 1/4 full of oil all the time when running and every thing seems to be getting plenty of oil. I may have an old set of rockers around and I do have spare heads. I'll look and see what you are talking about. If I can't find old set of rockers I will dig out the Fairlane in the next day or so and pull a cover. If it is as you say than I need to know. But Momma's car is in the shop and I only have a day or two to fix what I can before the road is opened up and She is gone to school with the boys.
I have done this to several Y,s and have had no problem. But need to look and see.
Thanks

 

I would think if the valve covers are filling up then the oil will travel to the drain holes in the heads to those parts any way. It has to get back to the oil pan. By attaching the hoses to the vent tubes the oil flow in the rocker shaft is reversed but will lube the rocker arms and then drain away.



I have a 3 color diagram of the oiling system in a copy of The Ford Mechanic which was printed by Ford for their factory mechanics. I could scan it in if anyone is interested.

 

Yes Roger i would like very much to be able to print it out thanks

 

The article is in 3 jpeg files. PM me with an email address I can send them to.

I have to agree that the excess will drain down and lube the parts, however
by having the oil bleed off thru the tubes only a small amount of oil got trapped
in the cover, now you jack up the pressure and those old rockers and shafts are
loading cover so this is why you need a regulator. Before the tubes acted as the regulator, reducing oil pressure in the shaft and carrying away the excess.

PS The old Chevy 215 lubricated the rockers with less than 15 lbs of oil pressure and it had a drain in the center of the shaft.
