Second hand forged rods - what to look for?

[evopwr]

Looking at buying some second hand Eagle h-beams for the build.

Without using precision measuring equipment, is there a way I can inspect these to be sure they are fit for purpose?

Obvious one is big end/piston pin surfaces. However I have heard of these rods stretching/twisting. How can I test them for this? Anything else obvious to look for?

Cheers
Alex

Its really only your engine builder who can measure these.
you could digital vernier them for length, and oval big end. But thats about it.

I thought this would have been the case...

What did the seller say his reasons for selling them were? And what power was he putting through them? Might give ya an idea of the life they had

 

[evopwr]

He reckons they were in his built motor pushing big numbers with 'no issues' then 'upgraded to other Rods in line with other upgrades'. That's the part that got me suspicious - why would you go through the trouble/cost of changing rods if not required.

 

[BYBY5L]

if ya can trust him go for it, but big power and used... how hard are you planning on pushing them,
ya gotta think how you'd feel driving ya car, can you give it a hard boosting and be confident the rods wont be the weak link,
Exact reason I went I beams was for peace of mind,

Take them to engine shop for inspection. Maybe even magnaflux them.
But gets pricey compared to stateside prices. They would want to be pretty cheap if you want to check them thoroughly.

You can have 3 of mine.... lol.

 

[4piknup]

The 3 bent ones?

 

[Cranked]

No. Actually in saying that I've not looked. The 4th is ummm.... MIA

Exit stage right 》》》》》》》

Did the old block chop disappearing act.

I would not go used eagles, used carrillos maybe, but for the cost of eagles, once checked etc might not be worth it

Did the old block chop disappearing act.

Was a decent block chop too.

The eagle H beams I have are only rated to 600hp, that could be what he means when he said he was upgrading, probably wants to be safe and use stronger bits if he's chasing more powaaaar!

I would agree with George here, for the price of new Eagles i would just buy em new.

 

[EVO-00X]

Exactly my sentiments George and Cranked.
Used rods without any magnafluxing or inspection by a professional is just too big a risk if they let go.
Its not worth destroying a block, pistons, head, valves, crank etc just to save a few bux in the lower end of the market to begin with.
Buy new Eagles.

Don't cheap out Alex - you've come this far with the car, you can't really justify going 2nd hand rods in your engine build to save a few $$$. There are some things you can skimp on - and there's others you just don't.

Pretty sure I got eagles and wisecos for less than $1k shipped.

Dollar is a bit worse now.
