had a bad torque wrench which the rockers where torqued to high, 7 broke and got crushed by the camshafts and got into the block which clogged up my oil sump pick up, which the enigne got no oil, and 20mile down the highway threw a rod due to the engine locked up and was in gear and a sudden shock broke the rod
note alway torque ur bolts to the right torque settings, i learned from that mistake years ago when i was starting on these lil import motors
