Nova S21WCS09 - Broken Conrod

When idling, temps were between 85 to 90. I try to keep it within that range. I do know the importance of getting the engine up to temp asap. But admittedly, am quite new to all this. I try to read what I can and then apply it.
Obviously have not been reading enough and something obviously gone way wrong some where.
the conrod that broke was the original conrod (same used throughout the breakin process). so i guess lesson learnt. expensive lesson.

guys, you have to pull down your new out of the box engines. i have sen so many have tight piston pins. this doesnt allow the piston to rock freely, and signs of damage can happen real quick. this wears the piston on the skirts, and the top grooves, and drags down the liner, then back up. is definately something to look at in future.

by piston pin, you are referring to the wrist pin where the conrod attaches to the piston?
If the wrist pin is indeed tight, what does one do to rectify it? is the only way to change out the wrist pin?

That's what I was thinking too.
The only thing I see in "fixing" this problem would be to check what the actual diameter of the pin is, and what the diameter of the piston-pin side of the rod is.
Even if you do find the pin to be too large, or the rod to be too tight, how can you enlarge/reduce the two without going too far?
Good to point out, hard to fix IMO.

but first contact the seller before anything is done. give them the choice to replace parts, or the engine.
