Very scary stuff. I broke 3 off in the towers. I decided to chance getting the bits out with a combination of magnifying glass, dental picks, thin oil for flushing, and a swaged-down hose on the shop vac (a piece of that Techalon vacuum line works good). The engine ran fine after, as I reasoned any tiny particles smaller than the oiler holes would get washed out in the oil. But, you know, I am still worried a little about the cam bearings....naw, the oil passages are big enough to direct particles into the main flow instead of the bearing surfaces...I hope
