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) |

QUOTE Regarding the coloring, I am not seeing any Due to the the poor lighting in the pics, it is hard to tell if that is corrosion inside the crack. That would mean the crack was there for quite a while. Although it is hard to tell in the pics. |
