car deep stick broke Hi, my car dipstick for oil cheak broke i bought new one today but looks like small parts/part gone into engine , i asked Peugeot dealer he said its fine maybe it comes out when u change oil for now nothing worry about , what u guys think?is it ok if i leave it? The dipstick measures the oil level in the sump. If bits of the stick go into the sump, you might - just might - be lucky that the sump bolt, which is magnetic, might catch it. More likely it will catch the bottom of the crankshaft and cause major damage. Reckon sump removal will be in order - and better not to use the engine until this is checked. Replacing the crankshaft will cost about 600 as it's an engine strip down job - engine removal, strip down etc. Not a job for the faint hearted. P.S. The filter will NOT trap it, as the filter is in the upper part of the crankshaft not the bottom where the alien "bit" will go.

Your dipstick is plastic, what is left in the sump is just a small piece
