hey was trying to change me valve stem seals with my own homemade tool, however one half of an inlet valve collet (the bit that holds spring down and valve up, may be called summink differant!) fell down an oilway

will it be ok?!?

it was the oilway above and just to the left of no4's inlet valve, the one about 10mm wide

i heard it make a noise at the bottom, was that it falling into the sump? if so shud it be ok, as the pick-up pipe has that gauze covering it
