No Top End Oiling

A really good engine shop just rebuilt my A460 engine, installing new A460 heads and the first roller cam I have ever used. I was a die hard solid flat tappet guy. Installed the engine and went prime the oil system before firing up, and got only an occasional drop of oil out of a few of the push rods. have not pulled the manifold yet, but I read on another blog of a guy having the same problem with a new roller installation in a Windsor. Most of the guys on that forum thought it was probably the lifter oil hole being to high to match the lifter bore slot. Anyone ever have this problem, and if so what is the easiest fix?

Which lifters do you have?

On the right is Keith Fulp's Crower lifters with the nano groove from the oil band to the edge orfice.....as delivered from Crower.

This a picture of the Crane ultra pro lifter with a similar groove...hard to see....as delivered from Crane.

.....and if your lifters do not have the factory groove, it is easy to make one. A small dremel tool makes it simple. Washing everything just takes some time.
Nice pics, Lem!

Thanks, Lem. Need to get this thing going and test those A-heads you sent me, and see if they out perform my old Eddy heads.

If its the really good machine shop south of town, you'd better check and make sure the galley plugs are in. I'll guarantee you if it is that shop he didn't check tolerance between the lifter and the bore.

May try turning motor 1/8 turn at a time and prime oil system
If you get all rockers to oil[not all at same time]
it'll probly be fine.
I've done that in the past and got along just fine
The alternative is to notch lifters[start small if you do]
