Hi everyone hoping to pick some brains here
I’m currently rebuilding a rover v8 3.5, I’ve have the bores oversized and the crank re ground.Upon reassembly I’ve noticed the new big end bearings have no oil hole to squirt up the bores but the old ones have.Ive called the machine shop that did the work and supplied the bearings and he said they obviously arnt required anymore and have been done away with ..... can anyone point me in the right direction last thing I want is another knackered motor

This is the oil way in question I’ve drawn round it because it’s a bad pic , it has the new bearing fitted

The bearings I have in my engine (4.6 P38 engine) do have those feeds present.

I share your concern about them not being present...

Chris.

It’s seems some do and some don’t .... like the performance pistons don’t have it ....
