Damn that sucks. Wonder if a full rebuild at some place like RAS would make them last longer.
what are you spring pressures?

Many of us have had good luck with Mancini rockers with the Trick Flow heads
Mancini Racing Aluminum Roller Rocker Arm Kit
I got my trickflow heads,head bolts,prw 1.6 rockers, rocker correction kit and Smith brother push rods through Mike at B3 racing. The heads went on my 2000 magnum 360 straight out of the box. Been running for over 2 years and lots of 7000/7500 passes. With no problems. So I woukd be very interested in hearing what problems you was having the prw rockers. The only thing is I wish trickflow woukd of put in more side clearance for the push rods. I have 3/8th size push rods and the clearance was really closeThe prw rockers didn't require much of a shim from b3 to line up nice.
But I've had problems with them.
So I put the 273 rockers back on for now.
I will probably start another thread about that at another time.View attachment 1715978563
I didn't see it in the parts description. But will those allow for push rod oiling ? Thats why I went with the PRW rockers. Pluse the PRW you can get in 1.6Many of us have had good luck with Mancini rockers with the Trick Flow heads

I agree looks like when I feel better I better remove mine and look them over. I have open headers on my 91 dakota, so I dont think I could hear any valve train noise. But the last time I checked the valve lash everything was good.Thanks for that information. First I've heard of issues on the PRW ones. I'll be sure to verify my oil supply and keep an eye on them.
Don't want to divert the original thread throwing guesses at what caused it for you.
Interesting, thanks for sharing.Ok Well if it helps you avoid a problem then
I'll share my experience so far,
Mine keep wearing out the bushings
You're welcome,Interesting, thanks for sharing.
I will be running these on my next motor and are now feeling a bit uneasy about them.
Just an observation - your adjuster looks too low, the set I have the oil passage to the adjuster is quite high, you need the adjuster down around 1 turn from stopped to line the passage up. But mine have 2 bushes per arm with a void in the middle instead of the groove cut into the bushing like yours so they might have revised the design and moved the oil passage at some point.

Questions like thst are above my pay grade.lol but I can't see how it wouldn't hurt. Or have groves cut in the bushing that will allow oil to flow through.The Comp's have two bushing on the ends with a cavity in the middle of the bore that would fill with oil.
Do you think something like that would help the PRW's?

Those comps suck and are a stupid design.The Comp's have two bushing on the ends with a cavity in the middle of the bore that would fill with oil.

The last time I checked you can't even buy replacement bushings for them. And if you convert to full time oiling they flood the upstairs of the engine..
A banana groove on the shaft and a full length bush is the way to go.
My PRW stainless rockers have two bushings with a gap in the middle as well. Good point about the adjuster too. You may want to make sure the passages are lining up.
That's nice for you, but in my world they suck..Mine have been in the for 11 years and 15K miles…
They’re not wiped out like mopar65’s.
Can you buy replacement bushings for this PRW’s?
interesting… wonder when yours were made/bought in comparison to mopar65’s ?
I put those prw 1.6 steel roller rockers on a 360, 10 years working fine..though one time an adjuster came loose and let a push rod loose. Missed..sounded funny ..so pulled the cover and found it, put it back it..good so far. Tightened them all the same...never had that happen before. Ever.Those are the PRW stainless ones?
I went with Comp's 10 years ago. They are pricey.
Wondered if anything else out there in steel with rollers that were reliable.
The reason I brought this up is because if you look at the CC rockers you have, you will notice they have a split bush in them, which is not honed, instead of the solid pressed in and honed ones most rockers have.Can you buy replacement bushings for this PRW’s?
And or thick rocker shafts...or they gall.Yep, got to keep cool oil up to those..
