StageV Conversion Heads with StageV Stainless Exhaust Rockers.
Anybody got a better Oiling Solution for the Exhaust Rocker Arms ?
Pushrod Cups just aren't Oiling enough? Just how in the heck are they supposed to get Oil into the Pushrod Cup anyways? Splash?
Lifter Pushrod Oiling doesn't seem viable, because ONLY EDM Holes in the Lifter Bushings ?
Am I in a "Spray Bar" situation, or is there a more positive Pushrod Cup/Adjuster Oiling Exhaust Rocker ?
Any ideas appreciated. thx Bob

here's a seldom used trick that I gave to Duster Dave when he was burning up his pushrods. Banjo style fittings were made to use on top of the rocker stand bolts. Then supply lines run from them to the cups.there's a bit more that needs explaining to make it work. too much for me to type so check your PM.
I know this system is still working on the car because I own it now

Geezuz ! WOW that's PURDY !
Thanks HEMIFRED, that's kinda what I was wonderin for a solution ? I'm gonna have to get Fabricating !
How the HECK are they supposed to get Oil into the Pushrod cups "normally", without any Oiling Holes in the Exhaust Rockers ? Are they usually just "splash only" stock on the Conversion Heads ?
Nonetheless, YOUR solution looks like the "Ticket"
Thanks Bob out.

My Problem, is the Exhaust Rockers Have NO Oil Hole in the Rocker Bushing, OR, The Rockers themselves out to the Adjuster/Pushrod Cup. NADA, Zilch !
Can't use Pushrod Oiling Lifters, as the World Block Lifter Bushings have only EDM Holes, not enough Oil Feed for a "pumping" style Lifter.
Gonna be fun figuring this out ?

Have you taken an adjuster all the way out of rocker to see if there is an oil feed hole into the threads of the adjuster?
If there is no hole feeding oil into threads of the adjusters or a hole squirting oil into the adjuster cup (more normal) Then sounds like they just missed that machining operation. I would call Stage V about it after I doublecked there is NO feed hole of any kind to the pushrod cup. I highly doubt they are trying to rely on splash oiling for rockers they know will most likely be used on Solid Roller (high spring pressure applications)
Also just FYI, if your lifter bushings have any oil feed hole in them, they can be pushrod oiled.... you can run as small as a .020" oil feed hole in your bushing & still make it a pushrod oiler, you don't need a "big hole"

Thanks Ryan Yes, NO Hole in the Threaded Adjuster Hole either, or anywhere in the Rocker Bushing or Rocker if it WAS there.
I have not had good luck supplying Pushrod Oiling Lifters, from just an EDM Hole on HEMI Pushrod lengths, as the Volume of Oil even in an .080 Internal Pushrod passage seems to limit sufficient lube at rpm ? Maybe I should have tried bigger internal pushrod Volumes in the past ?
Anyways, Gonna end Drill the Intake Shaft Bolts(like a 340 T/Plate Bolt) which go down into the Shaft Pressure, then Braze 1" Copper Tubes pointing at the Exhaust Cups. Should work / Stay Tuned and THANKS for the help Fellas !
Bob out. I'll get photos up if it works.

Here's what I did, just a modification to HEMIFRED's system, and a BIG THANKS to HEMIFRED for all the Tech support and HELP ! GREAT GUY ! Thanks again HEMIFRED !
I drilled the Rocker Bolts end to end, then attached some copper Oil Pressure Gauge tubing, with the ends crushed down around a .015" number drill. It drips on the Exhaust Adjusters just great !

Is this a problem only with certain rockers? I have DLI rockers w/ Manton adjusters, MP stands, and MP banana grooved shafts. All out of the box stuff and I've never had any problems burning up pushrods.

We have seen DLI rockers sold through Mopar that weren't drilled at the barrel facing the retainer,spring and valve tip on the intakes.The ones that came from DLI were drilled.We drill them.Also on some early Indy rockers that weren't drilled for oil passages that we had to drill.Indy has long since corrected that issue.I still have the drilled Indy and DLI on a few of our engines.Mostly we had issues with the oil passing through the heads at the head bolt into the stand that had the oil passages.Usually when using aftermarket head bolts or studs that weren't undercut they would shut off much of the oil passages.We enlarged the hole in the head or used an undercut bolt or stud to correct this.The grooved cam journal or crossover oil line also helps.On the Indy heads with the cast in rocker stands we sometimes enlarge the hole in the stand clamps at the oil passage stand and champhered the hole in the shaft if we felt there was a restriction there.Hemi rockers are noted for air lock and when we prime the engine we usually loosen the bolts that hold the shafts on all the ends of each rocker shaft and tighten them after a good flow of oil appears.

INFO SENT FROM STAGE V WHEN ASKING ABOUT OILING CONVERSION HEADS how did they oil exhaust rockers ? there seems be no oil routed anywhere to feed the exhaust Quote:
Most likely you may have a cheap adjuster made out of a set screw or OEM Chrysler. The splash oiling seems more than adequate with a good quality pushrod and a tool steel adjuster. The exhaust side tends to be less of a problem, because the angular movement is much less than the intake. Also the exhaust adjuster is not shrouded like the intake, so the splash does a fairly good job. I would highly recommend oiling type lifters, as they do not take any oil from the main oiling system. They simply divert oil that was already lost lubricating the outside of the lifter up the pushrod. You can purchase oiling roller lifters from Gary Burgin Ent.
Ray Barton does build a spray bar for the Hemi. One of our customers came up with a rather ingenious oiling addition. They drilled the rocker shaft bolts on the intake side to squirt the exhaust adjuster.
Usually with a good tool steel adjuster, there is not a problem.
