Any one interested in the oiling mods I did?
Ok, here are brand new, never used W2/5 rocker shafts.
You can see it has 3 sets of oil holes per rocker. One oils the shaft under the rocker, one hole is used to spray oil on the valve springs via a hole in the rocker in the notch for the valve spring, and the last one is to oil the adjusters.
The really important one is the one that has to get oil to the adjusters. Even on these shafts, and even though the oil hole is there, it's not clocked correctly both radially and laterally.
As near as I can tell (and I'm pretty sure I'm right) the holes are clocked for T/A offset rockers. Every set of shafts I've bought or used has been wrong. AFAIK, Chrysler never made a shaft with the holes in the correct location.
If you correct the location of the holes, and if you keep your idle oil volume (and pressure) up (I don't like to go lower than 40 hot idle pressure) Chrysler oil timing will oil the adjusters with at least 340 on the seat, 900 over the nose and net .750 lift and will do it easily.
You can't groove the shafts to the holes and make them oil (BTDT). The hole in the shaft MUST align with the hole in the rocker when the valve is on the seat. If you do that, and if you keep the volume and pressure up at idle, you'll almost never kill an adjuster.
Why Chrysler didn't address this I can't say, but I'm damn sure they know about it. I sent in the paperwork to MoPar Performance to prove they were either nuts or liars.
If you fix the oil timing, it renders pushrod oiling obsolete.
Edit: forgot to add the pictures!!!!
