The m8s use needle bearings for the cam... wasnt that an evo issue? I would pull the oil pan and use the magnet to try and find it, then if not there id pull the oil pump to be sure its not lodged in there.

Maybe buy a flexible magnet sheet
Amazon Amazon

Cut a strip with scissors & feed it down into the hole?

I’m gonna try flushing mineral spirits through the bearing hole and see if it flushed out through the pump. I’ll also try the magnet strip, for some of them at the house

Are you absolutely sure it didnít fall into camchest then out into drip pan. I would sift through all the oil before dumping mineral spirits in sump. Im not sure how one of the bearings could go back into sump if tool was installed correctly. I can only imagine how you feel right now.

I did not have the rod all the way in at first, I heard a crack, then pushed it all the in. The cam bearing came out without problem that time. I looked in the cam chest and pulled the oil pump, didn’t see it

Do you know for certain it had all the needles before you used the puller? Do you have any kind of magnet on a flexible shaft you could insert through the bearing bore?

You could try to flush through the bore with something like kerosene using a funnel with a hose attached into the bearing bore. Hopefully it would wash into the cam chest. Remove the oil pump first.

If you flush it, do an oil change afterward.
