I just refilled my clutch fluid on my car and the little gasket, rubber ring between the cap and the reservior fell into my engine somewhere. I spend probably an hour looking for and came up short. Do I need this part, if so where could I look besides the dealership. Appreciate the help. I screwed the cap back on as tight as I could, hopefully no fluid will leak out. Thanks everyone.

if u havent driven it take an air chuck in the engine bay everywhere its light enough the air pressure should make it fly around and fall out of whereever its at other than that junkyard it it will fit in ur pocket perfectly lol just tell em ur looking for something else like the way some wires are hookled up in a car under the dash and bring a digi cam so makes u look serious lol ive done it a couple times for small parts otherwise theyll either tell u they dont have it or they will want arm and a leg for some parts
