That's what machine shops are for
Tried pressing out a wrist pin, using a custom made mandrel, but it was obviously not going to work due to too soft metal. So admitted defeat, and ran the parts out to my great guys at the machine shop. They said they see lots of these grenaded SPIs.
So back to cleaning parts, and after reading about it here by chance, I'll also flush out the heater core and radiator.
