Rod Bearings Top & Bottom

Are you using stock rods?


Those bearings don't have the "notch" for the oil squirt hole for the stock rods. There are bearings available for the squirt holes.


Some aftermarket rods do not have the squirt hole and those bearings will work fine for them.


You have to pay attention to the Main Bearings. Some bearing sets only have holes in the top bearing shell for the oil passages and none on the bottom. If you put the bottom shell in the top hole, then you block the oil from getting up to the cam and top of the engine. For main bearings, the shell with the hole goes into the block, the one without the hole goes in the cap.

For the rod bearings with the squirt hole, it doesn't matter as the notch is opposite the anchor slot and is in the center of the parting line for both shells.
