Anybody ever seen a broken crank? I just tore down a 3.4 V6 from a Chevy Lumina that I though had a real bad rod knock. Turns out the crank broke in the webbing between #2 rod and #2 main. The amazing part was the engine actually ran this way. Well, at least it sorta ran. It was making so much noise I thought it was going to start throwing parts everywhere.

Sorry, no pics

 

hehe not sure, but I ran ~200 miles with a shattered piston on my 2.8L

 

Heh....I put about 4000 very hard miles on my 2.8 after the #4 rod bearing let go
