That is the oil metering disc from a hydraulic lifter.

That is the oil metering disc from a hydraulic lifter. Yep, but HOW? I've had a lifter explode when a pushrod got shoved down after a timing chain snapped and valve tried to fornicate my piston. But it left a lot more metal all over.

Can anyone identify this small mystery item found in the bottom of my oil pan. 340 4 barrel
Thanks It could be from a lifter, but kind of looks like that pattern those round casting marks in the lifter valley have. Maybe from the original casting core box?? Just thinking out loud.

But it left a lot more metal all over. Well we really don't have much information to go on. All we know is it's a 340. Why is the oil pan off? Is there other debris in the pan and this is the only piece the OP doesn't know? Was there a failure? Prior rebuild or repair? The last 340 was produced in '73 so chances are unless it's been stored somewhere for the last 30+ years it's had some work done to it.

Take an old lifter apart if you don't believe me. I don't know how or why it was in your oil pan but it's an oil metering disc from a lifter without a doubt.
