Some of you might remember the wrist pin bushing from before. I blame it on junk metal use in the 440 source rods . I will take that back now. last time we put it back together we use new wrist pins and new eagle rods.It has push the bushings out of the rods again. and we put a new sleeve in it. last time it crack across the back side this time long ways to the outside .this is the second sleeve both crack. I think the block should of never been used. might of bored in to thew water jacket ? I don't know was not there...But this wrist pin deal burn my a$$.. all I can think is he got them to tight ??

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, The cylinders could have been bored crooked. Check to see if the deck is parallel to the crank and then the bores perpindicular to the deck. Also, on the 440 Source rods I had to have my machinist hone the small end to get the proper fit. 2012 422 Allstars NSS Champion 2013 422 Allstars NSS Champion 2014 422 Allstars NSS Champion

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.

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

I going to put up some pics here in a min. But the rod bearing look like new so do the piston.
