I bought some scat rods used and looks like all the rods the wrist pin bushing(the bronze insert) is squished on the bottom and bulging out on the sides.
one rod is missing a bearing and others look like they had some particles squished in between them ( dirt, metal whatever it was)
guy said they were from a good running engine with low hours.

but theres nicks on them some surface rust pretty decent scuffing on the bronze piston pin bushing on the bottom .
i feel like it either spun a bearing or pston blew up on that one rod that doesn't have a bearing in it. since that's the only one and seen many people do that to cover up what really happened...they leave 3 good bearings and take out the damaged bearing and be like nah bro engine ran great. like butter...

i always used oem replacement pistons with oem rods this is my first time using forged rods with floating pins

 

Why would you buy used scat rods that look questionable?

just go get a new set of rods and scrap those.

 

Agreed. If it were a set of Crowers or something I might support sending them in and having them checked out and/or serviced. Not worth it on a set of Scats though.

 

guy said they are low mileage and no damage.
I didnt see anything wrong on the pictures they looked good

 

M4x. Bro maybe you want to buy me a brand new set since ure so baller that you can scrap and buy new...
Lol
Why do you think people buy used parts in the first place?

 

Buying used parts to save money only works if you inspect them VERY carefully first. In the long run it looks like you'll end up spending more because you tried to save.



FAST
CHEAP
RELIABLE


Pick any two. You can't usually have all three.

 

Most sellers claim low mileage, perfect motor etc. Especially Honda guys. If the bushings are damaged and the bearings full of dirt you can bet it was a shitty engine. No thanks, I'd throw the set of scats away too. If you can't afford new parts or purchase truly known good ones then I can foresee headaches on your horizon.

 

I get it. Maybe you can get a single rod? I'm not sure. I was more thinking that it depends on how much you paid for the used rods vs how much it would cost to have them inspected/magnafluxed and rebushed as needed. It could be less to drop back and punt on another used set.

Unfortunately, you have evidence that at least one of them was hammered pretty good. That pretty much means you need to at least go through them if you want to have some peace of mind in the new build.

 

Get a new set, not worth the hassle.

 

I got them on ebay so its still customer protection

all I want to know if the bushing is bulging out from normal use on them or is it from abuse
ive seen the used rods that have scuffs on the bronze bushing but they weren't bulging out on eagle rods. this is the first forged rods I bought so I have no idea how the bushing supposed to be when its used

ill take a picture in the evening today I just got them yesterday night and opened the box .

 

No, it's not normal . Most likely there was severe detonation or the pistons were tapping the head (bad bearing could allow this as well). You've been had, return them and save your pennies for a new set. If you keep them, you definitely want them measured for twist and distortion.

Do you guys remember the threads where people were receiving rods that were painted to cover a smoked big end? Classic... beware of painted rods LOL!

 

Lol i just saw a set of purple painted rods on ebay too

 

I'm not baller but i saved up for over a year to build my engine with quality parts because I didn't want to have to deal with shady used crap or a stock piston/rod combo. At least you're covered under ebays rules.

Besides. Eagle rods are far from "baller" they're under 400 bucks for a set. They're basically the cheapest forged rods you can buy.

 

Look i dont need advice whether i should buy used parts or not bro.
I have a swt of brand new rods for my motor.
This set was for another one im building i buy uswd parts alot and usually they are ok to use. Sometimes they are not... this is one of those times...

 

If i bought all brans new parts i would never be able to afford what im building and if i cant do that it makes no sense to build a motor that i dont even want

 

I guess you could get all 4 rebushed and balanced.

 

heres some pictures

 

WOW those things look horrible. Bushings are massively deformed and scored. Possibly from detonation damage?

When it comes to pistons and rods, it's always better to buy new rather than used. If you have to buy critical components 2nd hand to complete your builds, it really just sounds like you need to wait longer to save up the money to build them properly.

I have a few projects that are in the planning stages simply because I don't have money to build them right now nor buy the tools to build them. As a result, when I do have the money and tools, it'll go a lot smoother.

No money+more time=better planning.

Money+less time=less planning.

I'm not trying to knock on you or anything for buying 2nd hand parts, you just have to be a lot more critical about their condition before you buy them. Used pistons/rods should be in nearly like new condition, with obvious signs of normal wear on things like the piston crowns and skirts.

 

Like someone else said, can you just get new bushings for them? Obviously would be cheaper than getting new rods.

 

If the big ends are not damaged, then you can definitely have those re-bushed. I would have them checked to make sure they are not bent or twisted too. The machine shop can also re-con the big end too, for peace of mind. I would check the rod bolts too by tightening them to the torque spec, then put the stretch gauge on the bolt. Take note of the measurement for each bolt, then loosen the bolts, and re-measure each one, making sure they are within spec.

 

Yeah, those bushings are smoked. That guy lied through his teeth about the condition... everything I said before still rings true.


On a side note, that's not how using rod bolt stretch gauges work to see if bolts are beyond the service limit. You must know the original when still brand new measurements to have any idea on if the bolts are stretched beyond service limits. Don't believe me? Take it from the manufacturer themselves: (Click on the "Installation" tab.)

Since he purchased the rods used, I do not think he will know the original brand new measurement. The best thing for him to do in this situation, is to purchase new replacement bolts, and then install them using the stretch method. Since he is purchasing used rods, I am assuming that he would not want to spend the money for new bolts, so attempting to check them by the method I suggested, could possibly save him from a failure. I forgot to state that you measure the bolt before installing in the rod, then torque to spec, measure, then loosen, and measure again. Normally a bad bolt will show up using this method, but it is not a guarantee.

 

it seemed like a reputable shop they have 100% rating
their name is morseperformancegroup on ebay

I guess ill be returning them. its not worth the time and money to fix after all its gonna come up to same preice as new

 

thanks for yalll help btw.

you make stupid decisions when you re in a rush and somewhat broke lol.
i cant pass up a good deal on ebay i think my hoarder side is kicking in sometimes because i have 2 of everything now
my new years resolution is to stop looking on ebay and not buy parts that i don't need.

i did get a 99 cent ukdm accord steering wheel for Christmas on ebay

my 2 liter build is almost complete tho. all i need now is main and rod bearings and it will be going together shortly

hopefully the 94 gsr LSD tranny can hold up to the power its a viscous lsd

 

I think I paid $300 for brand new Eagle rods with the 7/16 ARP rod bolts, FYI.
One of the few cases where "good, cheap, and reliable" actually go together lol

Good luck on your new years resolution. Stupid decisions are apart of life. We all make them. I know I still do!
Personally,blocks, cranks, and camshafts are about the only moving internals I would consider buying used and even then theres still that chance,,
