Exclamation bearing break-in lube?

I just had the bottom end of my engine rebuilt with a new .010 Undersize crank, rod bearings, and main bearings.

My question is,

Would it be a good idea to add somthing to the oil for breaking in the new crank and bearings?

If so, What?

Nothing is needed specifically for the bearings . Just prime the system .

Most of the parts houses still sell SH and SJ rated HD 30 wts though. It would be a good idea to use some for the intial run if possible then change the oil and filter to remove some of the debris it has in it from the build .

It does not sound like anything was replaced like rings , cam ect , correct ?

Correct, No changes to the rings, cam, heads valves, or any other parts.

Some shops sell break in grease that you can apply to the bearings, especially the cam bearings and lifter surfaces and cam lobes(If you replaced the cam).

In a pinch I use STP, the thick gooey stuff for assembly lube. Just goop a little on each bearing and then torque it down.

Good Luck,
