I was getting ready to install my pistons tonight and I noticed the new rod bearings don't have holes drilled in them like the old ones do . Now is this normal ? The holes need to be there right in order for oil to pass through . I called the manufacter and they said they are the right bearings but I don't see how the oil would get in there .

 

Well I called summit racing and the new bearings are high performance racing bearings made for more rpms and better lubrication . So problem solved .

 

There is no need for the hole. The oil is suppied through the crankshaft and the bearing rides on a layer of oil between the crankshaft and the bearing. Oil doesn't go between the bearing and the rod.

 

As jck1961 stated, rod bearings do not have holes in them. Just a plain split bearing. Only the crank main bearings need holes for the oil galleys to feed them & the rods.
