Stainless, Bushed PRW Rocker Arms

so, did you go to pushrod oiling? And if so, did you block off the shaft oil passages?

It has both
Pushrod and Shaft oiling.
I added pushrod oiling before I sent them to RAU.
That still did not keep it from wearing out the Rocker Arm bushings.
I left it that way even after getting the re-worked Rocker Arms back.
It's been fine since.

I just wanted to add that it has a high volume oil pump, I'm not sure if I'd run both types of Rocker arm oiling with a standard oil pump.
Also this is what I would call a Hot Driver not a Race car.
I don't spin it much over 6000

I'm guessing your oil pressure is fine. Surprising since you're using 2 completely different oiling methods. When I made the move to PR oiling, I put setscrews in the block to stop that factory stuff. Been using factory PRW rockers 4 seasons now. Springs are 640ish pounds open. Solid roller. No problems. Yet.
 
I'm not sure why it was wearing out the bushings and also flatting out the roller wheel tips on the out of the box prw's.
But while I was waiting for them to come back from RAU I put on a stock set of 273 rockers and shafts with only shaft oiling and drove it that way everyday for a couple months, when I took them off there was No sign of wear.
I'm pretty sure they had banana grooved shafts and that may have the biggest difference in wear.
I'll have to dig them out to confirm that.
I'm glad you are having better luck then I did.
Thanks

How old are your rockers? Mike at B3 worked with PRW to update the rockers.

One issue I have is they didn’t make the rocker with enough ratio in them. I think mine measure 1.610 and the new rockers measure 1.651 IIRC.

That’s a huge deal alone. They also made the rocket have more spring clearance but that wasn’t needed if guys would just correct the geometry.

If yours are older like mine (I’d have to talk to Sean at PRW again to verify but I think I’m close) then they may have updated the bushings in the new ones.

I’m never a fan of a split bushing like they do it.

How RAU or what’s its name fixed yours is how they should be made with a solid bushing and the oil hole plugged in the top of the rocker.

And that hole is about 3 times bigger than it needs to be.

I bought them from Mike @b3 around may 2019
At the same time I went to TF heads.
He was a Huge help after the first set of bushings wore out he warrantied them.
Then that set did the same thing he helped with sending RAU some extra needed rocker arms and shafts to make 1 good set.
He stepped up even when PRW didn't.
I really hope they made the necessary changes to make them a better product.
I can't say enough about how awesome Mike @b3 and Gary at RAU are!
Thanks guys!!
 
I have this same set up, trick flow heads and hydraulic roller from Mike B3, the time line, probably around 4 years ago. I haven't had a bushing failure like that, yet. I probably have 5 thousand miles or so on it. I have always had a ticking, my rockers and shafts appear to be fine. Have adjusted the lifter normally and currently lashed like a solid roller. Same ticking. Guess that I have just gotten used to it. I do check it often, just can't put my finger on anything. Have also replaced the roller tappets. No change.

You might want to call Mike and see if you have the updated rockers just so you know.
 
I got mine from Mike, too. They are the updated version also. No more aluminum for me since a Hughes broke on me. I wouldn't even buy a T&D or Jesel aluminum. I do too many street miles. Saving up for T&D stainless........they're pricey and a 3 month wait time. I guess they build for order.

Seems so far, the PRW's are fairly stout. I just wish I got a little more oil to the roller.
