Man look at the hell storm I found on the diesel place over some rods

The Still Master
I am going to make a few very simple comments and history proves time and time again that no matter what you try to do some facts remain that can not be changed.
1.) YOU GET WHAT YOU PAY FOR, PERIOD.
If you want to pay less something will be as Pat said skipped to save money or the part is simply not going to be as good, just like all things in life you always get what you pay for !!!
2.) EXPERIENCE/HISTORY IS THE BEST TEACHER.
How do you think Crower and Carillo got where they are ??? By making mistakes, yup they did, but the mistakes made allowed them to figure out what the minimum needed for steel strength is and the heat treatment to make the parts hold up. I beleive they also check parts at random like all manufacturers do to ensure specs are being met. Also you always spec a part for what you think you need and then usually overbuild a cushion into it.
3.) STAND BEHIND YOUR PRODUCT OR SERVICE.
Not everything in life is easy, and it is far easier to walk away from a problem then fix it, but those that man up and do what is right for all involved will be around, those that don't will be out of business.
JMHO.

The biggest problem is that folk can't separate parts from personalities. There is a difference.
Whether you like someone, or hate someone, it has no effect on the parts.
Yes, 4140/4130 is not the popular choice for connecting rods. Everyone uses 4340.
Yes, a metallurgist would be the best person to evaluate the failure. Remaining sets should be magnafluxed, chemical tested, and checked for hardness as well.
But a metallurgist should have been in the loop BEFORE they hit the shelves.
This is not the first time a company outside the metal mfr'g industry made a blunder by not calling in folk who do this stuff professionally. ATS made a bunch of turbo pedestals that were of the wrong alloy for application, but all they did was warp. IIRC, ATS made it right to the customers.
There are a number of great machinists on this board, but one aspect of being a great machinist is knowing what to use your skills on, and when you need to call in specialists.
I wish these rods wouldn't have involved an EFILive tuner who has helped lots of folk, because it colors the issue. But parts are parts, they don't care.

An X-Ray would be an excelent way to help evaluate remaining rods. It would show any underlayment cracking, and it will also show some stess as it will give you a picture of the metal density. I deal with this crap all day long at work. Something broke, firgure out why it broke, make it better. These would be pretty easy to figure out since thermal expansion plays no role in it, and that is what can often make it difficult to figure out what went wrong.
Check mine...there's probably a hundred different IP's. Happens when you travel like I do.
Something ain't right with sillydumbass though...I still say his truck doesn't exist.
It probably doesn't, and he probably is full of it but theres no need to call someone a dumbass. For all anyone knows he could be mentaly ill.
You should try looking in a mirror before you call others names. It's usually a sign of insecurity and sexual fustration.
I'm not mentaly ill thank you very much

OK folk, this was moved to Tech for a reason. No more personal attacks. After this, I will clean up the thread if necessary.
I think that if you cannot prove he doesn't own this truck we have to give him the benefit of the doubt.
That thread got chopped and locked.....RDL got smacked good by someone, but it was deleted...funny.
So in all this, if any of you were in this position what would be your next step? I think a good lesson has been learned here, but I think Nick should push on and investigate and do what he can to improve on his design IF they were not strong enough. What happens to everyone's thoughts when they turn out to be as described after testing?
Pretty much. This time actually do what all rod makers do, metallugical testing, engineering, inspection, etc.
There are at least 5 rod companies manufacturing Dmax rods now:
Crower
Carrillo
Cunningham
Howards
R&R
that I'm aware of, and I believe there are more entering the market.
I remember talking with Guy Tripp years ago, who is an expert machinist, about making rods when I could not buy rods since I was on the NoSoup list. He had told me that rod making, much like making gears, is a science, best left to those who have decades experience in that area.
Sure, anyone with a mill could make a rod. But not everyone SHOULD.
If in fact these parts were not made using the procedures normally used for fabricating high stress critical steel components, then the risk was entirely on whoever thought that was acceptable. The buyer is responsible for researching what they are ordering from a machine shop, and the inspection is adequate.
The real "buyer" here is not the enduser, so the enduser should not be held accountable. Right now, if I understand it right, all the risk has been absorbed by the endusers.
I spun a main bearing in my motor, out of how many that popped a piston at our level? Just thinking maybe it was snag in a single rod. You dont know for sure like I dont. Im just curious like everyone else is. Like everyone else said we need to see what the results are of testing.
Whats wrong with your motor, I'm still waiting on that lol.
Let's put this another way.
You bring your truck in for an oil change. The dealership owner sells you the parts and services. There is a massive screwup due to not checking the oil level, and the engine blows up. The dealership decided that to cut corners, they would have the janitor do your truck.
Who should fit the bill?

Wasnt there some testing done? I remember hearing a strength number on these rods awhile back, seemed like it was a 'psi' number. My other thought, out of the 5 you listed, has any of them had problems like this with there rods? There a huge company, perhaps we never heard of the ONE case they had, even if it was a rod in some dudes 350, especially if he didnt have the internet. lol.
IDK, I guess when people are trying new things for our community I think its great, Nick has done well in my eyes and he is simply trying to make things better for all of us. I see your point about people vs. parts.
