Thats strange that they are all pushing out. It would seem that they may be all on the tight side. But , I wouldnt figure that they would all want to push out. Are they pushing out all the Same direction?? as in All towards the back of the engine or the front. Or just all random directions both front and back?? If its direction one way , that may indicate that the crank is not parallel, perpendiculularly with the cylinders maybe. Just thinking out loud here,

did u pin fit the rods ? all brand new rods need pin fitted to the piston pins u are useing , even my 1600..00 olivers needed done i put 9 tenths to a little over 1 thou depending on application ,no2 and blown/ turbo need more because they will gauld the pin to the bushing easy !!

Jamie these are full floater correct... where are the locks at... did they push out EDIT it can really be only 1 thing(my opinion) that the press fit of the bushing into the rod isnt tight enough and for some reason the pin to the bushing has more friction then the bushing to rod... the pin must have been too tight on the fit

Could you post some good clear pictures of the front and back of the rod bearings as well as the big end bore (rod half, not cap half) of 2 or 3 connecting rods please.

Now you can't say a bad word about 440source ever again
I'm betting the block was machined wrong but it is hard to say. Did the pins get oil on assembly?
Yes I put the motor together and yes they had lots oil on them. motor has 250-300 runs on it. maybe more. I got some other 440 source parts I can complain about..But I can't blame the rods now.

The bushing need to be a interference fit to the rod either by heating and expanding the rod or freezing the bushing or both.Then fitting the bushing for the pin.To only press fit the bushing in the rod can cause the the bushing to come out.
These was new eagle rods. the bushings was already in them, But I did have the same shop put new bushings in the 440 S rods. Have not use them yet will have to have them checked out now

Another thing you can look at is do the rod bearing showing wear at the crank side.If they were riding on the crank radius it can angle load the pin causing the bushing to galled.
I going to put up some pics here in a min. But the rod bearing look like new so do the piston.

Why no spiral locks? I would say thats your problem with the pins coming out.
These pistons do not use spiral locks. pins are not coming out, not all piston use spiral lock

Quote: "this is the first time I have had the bearing out of the rods. not so pretty. ???" I don't know if that's bad after 250-300 runs. That's alot of laps. That said, I'm no engine building professional, but I DID stay at a Holiday Inn last week. LOL On the rod bushing issue, I'm thinking too what the P man said: it can really be only 1 thing(my opinion) that the press fit of the bushing into the rod isnt tight enough and for some reason the pin to the bushing has more friction then the bushing to rod... the pin must have been too tight on the fit

My opinion....everyone is WAAAAY overthinking this.....the pin fit was done wrong. My

440Source told me right up front the pins bushings needed to be honed to fit.

Time to pay your dues to the guy upstairs to stop the hating, that may change your "luck" Just kidding Vern, I sincerely hope it gets better for you and yours I've seen black spots on the back of the rod bearings and in the rod where the bearing sits caused by detonation Mainly lack of fuel delivery the last three hundred in the 1/4 mile

I absolutely agree with Todd on this. I used new Ohio Crankshaft rods on my build a few years ago and took the rods and pistons to my machine shop to have them fitted. They fitted them with approx. .0003" (if I remember correctly) like they do all of their engines (mostly BB Chev). After talking to Todd, I took them back to the shop and ask them to hone them some more, to approx .0008". They didn't want to hone them that much. We settled on approx .0006". No problems so far. They felt like the bushing were being honed to "worn out". My position to the machinist was MY rods, MY bushing, MY engine, MY responsibility. This is not a Chevy. If they are worn out in a season, I'll pay you to put new bushings in then. The problem that you (Jamie) are having is exactly what Todd warned me would happen if they were too tight. Thanks again Todd! Getting ready to start the 3rd season on this engine. It has been freshened up (bearings, rings, valve springs, ect), rod bushings still good.
