Put my engine back together in November, and have been driving since then. Couple of 200 miles drives, mostly around town. Itts a 2056, webers, cam, nothing super high power. This weekend it started an awful clunk deep inside, and I got it off the road and towed home.
Got her puller apart, and here is what I have found. Crank broke threw the rearmost counterweight. How does this happen? So I need a new crank. What else should I replace? Obviously all main bearings. Rod bearings too? Attached thumbnail(s)  Attached image(s)
