I did about a month ago.... and the #s I told him I got were ok, but in his findings, he found the springs he's tested were much higher, even on a used set. Now, this was at DC, and the tool they used was a very sophisticated spring tester for valve bodies, or something... so he was questioning the accuracy of our spring tester (and for good reason) at work. Our's has a factory calibration kit, and it's checked quite often, and also found to be real close to what they see when they order springs from stock to wild. So.... who knows? I believe he told me (sorry 5D if my "mammory" is bad) that 90psi would be kinda too low, especially on a higher boost application for the same reasoning that I believe.

Sorry, but it is worth it... it is a rare thing to have happen, but Murphy's Law usually sux.....

i'm with Steve here...it's definitely worth looking at. I've never had one fail, but I have a number of rockers I've pulled from other motors that have had the pin walk issue.

Not sure what your talking about, the NFL started it, gazer city, guess that's why alot of you love it, azz lookers and sniffers, yuck, :yuck:
It should be called "gazerball", not "football", real football is played in England, where shockers, they use THEIR FEET.

Sounds just like a more kinkier version to me? back on topic lol
Re: TIII billet aluminum mechanical rockers being tested.
I looked at my head and ive got a couple pushing out can i push them back in? and punch the ends?
Re: TIII billet aluminum mechanical rockers being tested.
That's something I'd ask jackson. I fyou don't press them back in correctly, you take a chance of squeezing the aluminum sides in and causing a multitude of issues. If they are just a bit offset, you're probably better off to leave them. But if they have worked out like the ones I showed... then maybe replace them.
Man, I didn't want to start a rocker failure frenzy... maybe Wallace should give me commission on the sales of these. hehe
Re: TIII billet aluminum mechanical rockers being tested.
Now that I think of it, I've experienced/dealt with three of these rocker arm failures. All failed the same way with the pin walking out one side and seizing up. The first time it was a few months after I bought my red Spirit R/T. I popped the valve cover off to fix a leaking gasket and found one of the exhaust rockers had failed. It had happened before I ever even got the car because after tearing it apart it was obvious that somebody had taken a grinder to the rocker and cleaned it up and reinstalled it (so it wouldn't lose oil pressure). You would be surprised at how well a Spirit R/T runs on 15 valves. I had no idea there was any problem at all..
Second time it happened it was on my white Spirit R/T a few months after buying it. I bought it with a bad turbocharger and installed a nice modded TII turbo to get the car going but right after I got it running again with a good turbo, one of the intake rockers failed. I didn't have any idea anything happened at all but it was too late....there was metal all over the engine, cam lobe wiped out, and a rod bearing knock. Car has sat ever since.
Third time it was my red Spirit R/T AGAIN! This time it was another intake rocker arm and it wiped the lobe right off of a LWP S1 cam I had in there. Metal all over the engine as well and found most of the lifter and disc (intact) in the oil pan. No bearing noise this time but the engine is still at the machine shop now.
Re: TIII billet aluminum mechanical rockers being tested.
Crikey! Now I am getting worried about my rockers. I will have the valve covers off this winter anyways so I will be sure to check everything out.

Ha, I gotta admit the thought has crossed my mind Jay. I even checked the EIN and it matched the VIN so I'm going to keep it original. Might put a 2.5L crank/pistons in there though.

I am surprised it took you this long to crap on the T-III.:eyebrows:
Re: TIII billet aluminum mechanical rockers being tested.
Didn't mean to make a big deal out of this.. Honestly I think I just had an extended run of ---- luck. Especially when it comes to my red Spirit R/T for some reason. But for the amount of effort involved in removing the valve covers to take a look, yeah totally worth it. It only stands to reason that as these cars get older this kind of failure will be more and more frequent. Most of these rockers are 20+ years old now.
I will work on getting some carnage pics up. Pretty sure I have pics of all three incidents.
Re: TIII billet aluminum mechanical rockers being tested.
Here's the first time I had a rocker arm failure in my red Spirit R/T. I popped the valve covers off and found one rocker arm sitting a lot lower than the others....

The rocker arm had failed before I even bought the car and somebody had ground the rough edges of the broken rocker and reinstalled it on the shaft so it wouldn't lose oil pressure while running. I had pics of the trashed cam too, but I had to go to the Internet Wayback Archive to get those pics and they didn't have them. At any rate I sent those cams to Lone Wolf Performance and had them welded/reground into S1 cams for the rebuild I did on the car back in ~'04.
Re: TIII billet aluminum mechanical rockers being tested.
Here is second rocker arm failure. This time on the white Spirit R/T just after getting a bunch of work done on it. Look how far the pin has walked! The photo is dark but I don't even think you can see the end of it anymore. Lots of wear on the sides too, worse than normal anyway.
Learning from failure #1 on the red car and out of spare parts, I ground down the rocker and reinstalled it so I could limp the car back home (I was moving at the time). The last two pics are after I cleaned up the fragged rocker but with all the metal parts I could find, mostly in the oil pan. The engine developed a nasty rod bearing knock soon afterwards.

Re: TIII billet aluminum mechanical rockers being tested.
And here is #3 failure which was in my red Spirit R/T again. I actually just now took these pics. I should have gotten a pic of what the rocker looked like when I found it but I think it was basically sitting 'down' like the photo above because the rocker had already barfed out the contents of the lifter bore. This time the damage to the cam (the LWP S1s I had reground after the first time) wasn't quite as severe since I was lucky enough to catch it fairly early. The major players (pin,roller,disc/swivel cap) survived pretty well but the lifter body and needle bearings got crunched up bad and most of the metal flake I found in the oil was probably from the camshaft regrinding itself on the siezed roller. The graphite shade of the camshaft is from the dry film lubricant performed at Lone Wolf.
