its next to impossible to keep it clean for any period of time. i put a plastic bag over mine after removing the pistons, i was not going to split the case. i pulled the bag off to check something and found sand where the cylinders slide in. i thought at first about removing the sump pan and washing it out, but my porsche guru advised me to split the case and check everything and reuse if good, he did not know about the sand, but he too also mentioned how he hates to have one partially apart/toghter and sitting because of dirt.
