I have a b16a2 in my ef and I was changing my valve seals last night and i lost a keeper. It fell into what I believe to be an oil passage under the valves...If anyone knows what im talking about....do you know where those oil passages lead to? The block or right to the oil pan???Not sure but need to know if something is going to be screwed up from it falling in there??? Thanks in advance

 

Slim pickup magnet,might have to try thru oil drain hole or drop pan.May still be in head though.Do NOT start it until ya find/get it out.G'luck!...
