The motor ran then died, started and ran four about 3 to 4 storkes then popped, so it blew while running. I have inspected the motor in great detail and there is no other damage, the crack shows signs of bad molding. I studied a fair bit of metal fatique and corrosion when i did my trade " helicopter fitter and later flight engineer"
By the way who is OP ???
