First lets clarify how/where you found the metal "shavings", how large are they, and what do they look like? You were "checking" the oil level and the shavings are on the dipstick only??.........or the metal "shavings" were in the oil pan and in the drained oil? We had another one of these on this forum a few months ago where the thread starter found metal shavings on the dipstick yet, and I don't know if we heard the final resolve on that one. Even a catastrophically failing car engine that is still running is unlikely to generate metal "shavings" that you would see in the oil. If the engine is running fine, making no "interesting" noises, and is not "throwing" oil out the tailpipe, then I guess it's possible that a post machining cleaning step got missed during the manufacture of the block or head. To protect yourself, get the car to a dealer, and with you present, they should drain the oil through a milk filter, save an oil sample and the "shavings", and check if there is metal shavings in the oil filter which means the oil pump swallowed this metal and should be replaced at least. We need more info.
