Mopar on the right. The pushrod seat is flipped over to show the back, where it contacts the metering disc (with 4 holes in it). Note at 9'oclock, you can barely see it, but there is a channel machined in to always let some oil up the pushrod. Also note the sealed power has only the metering disc with no holes, and nothing machined in the backside of the seat. Seealed power, $4, Mopar, $29.
