I thought that issue was "fixed" ...

One of the many reasons I would never run eagle rods for any application.

I would prefer stock rods over eagles.

 

sounds shady,

not good for eagles rep

 

i've yet to see an eagle break for reason other than install error, and i've seen them used in 500whp + engines with teh REGULAR bolts

 

Eagle rods or any aftermarket rods=race parts

OEM rods= realiable

 

Who installed the rods and did the work?

 

it's an M24 thread now

but, i was also wondering who did the bottom end work???

 

i love seein posts like these. it really could tarnish eagles reputation yet ive had my rods in my block with the standard bolts for its 3rd yr now. i have a tough time jumpin on the anti eagle rod bolt bandwagon because of this. my motor has seen well over 200 passes maybe over 300, ran on the street as a daily driver, the rev limiter is set at 9600 and i have hit it on occassion.

i agree hybrid901 just made 620whp in his car with eagles...Have you confirmed that there was NO chance of installation error?, tq'ed to the right specs? etc..

 

ARP /=eagle me

that's an ARP rod bolt...and NOT an eagle

oh, and the heat checks you spoke of would lead most to believe it would be oil starvation was the lead cause of destruction...


still, sorry about the engine dude

 

haha, man o man i just jumped to conclusion. i wasnt reading right. i didnt know eagle made rod bolts.

You trip me out Bert. Always represinting oem.

 

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by Highrevs99 &raquo;</TD></TR><TR><TD CLASS="quote"> Well , tonight we found the reason why Eagle has started putting bigger rod bolts in there rods . The rod bolts snapped on a B20 tonight and took the whole motor out . We are still getting the parts of the road . This motor was only a 200 whp motor and they should have not of snapped the bolts , I mean the bottom cam just fell off . So if your thinking of running these you might consider the 3/8 bolts they offer . I will get some pics tomorrow and everyone . I am selling my Eagles because of this , if they coulnt take this then I am very leary of running them in a boosted amplication . </TD></TR></TABLE>

Lemme guess...you torqued them beyond the 28 ft/lbs and/or didn't use the moly lube when you torqued them?

I had this happen to me personally in a B20vtec..but they were torqued beyond 28ft/lbs.

Two other motors built at the same time (one built by me) and not torqued beyond 28ft/lbs are still running, one a B20vtec and the other a boosted D16z. Follow the install directions exactly, and you won't have a problem.

 

I did this motor . It had over 100 runs on it but still the bolts failed . I am not putting Eagle rods in general down I stated it is a good idea to go with the bigger bolts . I check the bolt stretch and torqued to Eagle specs and they checked within spec . I have run Eagle rods in another motor that saw over 32000 hard miles and numerous 9500 rpm blasts . Eagle put bigger bolts in for a reason and not to make them good for 100 hp more . The beams are still intact , just the bolts snapped and the cap came off , we found the bearing in the road and guess what ; it was fine . I didnt start this thread to say Eagle sucks ; I was just recommending the larger bolts . Like I said pics will be posted and all can be the judge . As with any aftermarket or OEM , failure can happen at any time no matter the costs or how carefully it was installed .

 

looks like driver error to me...over rev the bitch or drove through a swimming pool and hydro locked the motor

 

I always find it interesting that when a motor goes, the first thing blamed are the parts inside, when 90% of the time it is the installer that should be blamed for the problems. I'm not saying that it's your fault, i just think you should think a little harder before you post "Eagle Rods = Motor Go Boom", especially when there are so many people who will immediately jump on the bandwagon and say a product is ****, when they know absolutely nothing about it

 

Hey, it was not drivers error it was one of those fluke things. This car was well maintained it saw the track just about every other weekend and run strong. There were no signs that this was going to happen.

 

I guess people are misunderstanding the post . I torqued them right and this motor had 100's of runs on it so if I installed them wrong I think the problem would have showed it ugly self . I am just recommending the bigger bolts if you plan on revving your motor . It is plain to see the bolts are what failed and with any part they are worked hardned . I have used these same rods in another motor and never had a issue but it had a smaller bore which means less stress on rod . Go ahead toss the dice and maybe you wont crap out but I think for a little more money the bigger bolts would be good insurance . I am not saying in any way not to use Eagle rods , just get the bigger bolts expecially on a big bore motor like a B20 .

 

I personally know highrevs99, he's ******* **** about torque specs, tolerances, ect. The motor was not over-revved, he was still in first gear with a 9000 rpm limiter.

Perhaps the title "Eagle Rods = motor go boom" is alittle misleading if your point is otherwise?

btw - looks like what happened to my B20..although the rod snapped in two places.

 

using a different (or no) lube will change the effective tq on the bolts. the 'slipperier' the lube, the tighter the grip at a given tq spec. follow strictly mfg's directions. don't substitute moly for oil, etc.

if you don't have enough grip, things will loosen, clearances increase, oil pressure drops, things overheat as they starve for oil, and....

if the necessary tq is exceeded, or you tq to spec too many times (e.g. in case of measuring), in tq-to-yield-type bolts, they lose their elasticity, harden w/plastic deformation, become brittle, and won't hold.

vibration can 'work-harden' material, too, so that even a properly tq'ed bolt will fatigue and eventually fail.

if you plan to replace bolts (on anything), remember that often, the material of the bolts is stronger that that which they're supposed to support, so if too much of the supported material is sacrificed, failure can occur elsewhere (e.g. the rod caps). sometimes you can get the same-sized fastener, but of higher-grade material to have a better compromise.

'a chain is only as strong as it's weakest link.'

 

the motor was put together well, i've talked to Dom about assembling motors before, and he makes my head hurt.

 

I have Eagle rods. I love them. Every manufacturer is going to have defects. Just b/c a set of rods breaks does not mean the company is bad. Alot of pro's use eagle rods and they are going to higher RPM's and are making ALOT more power than me and other people here on h-t.
Eagle rods.

Hell yeah. I got to bring beer to table, whatever it takes to feed my belly, gotta sell OEM , lol.


I hope no one took it the wrong one, but yeah, he's right, OEM represent, lol
