yea thats kinda what i was tryin to say, yes #1 rod is broken somwhere letin it go free to smash the valves. i saw no holes in the block and from sound i think it might have broken off around the rod bearing/cap leavnin the rod still attached to the piston beacause as the crank turns it only makes a slight tap sound vs. a scraping as if the rod was still moving with crank. as soon as i have time i will pull it apart and post some more pictures.
