well I started tearing into my 2.3 volvo penta that exploded 2 days ago. was running perfectly then this ( cpics) happened! absolutely no warning! when I first looked @ it I couldnt' tell much, just that the engine block was in pieces. I found some pieces of shrapnell I thought was the cause. A piece of a bolt and what was left of a nut. after tearing everything apart I am finding myself in a chicken or egg situation. 1) chicken- cam that drives the dist. broke, fell into the oil pan, wedged in between the piston rod and the crank breaking the piston rod causing everythig to fly apart. or 2) egg- pison rod breaks for whatever reason/cause sending shrapnell flying and causing the damage. either way the engine is shot and no amount of thought or debate can fix this. I've found a car with the same block and all my attachments are in working condition. so Im probably gonna fix it again.
