Confused, what pump? and do you mean you want bearings made to measure? Which bearings you mean? And whats your plan?

Id suggest trying a thinner oil before swapping bearings. The thicker the oil, the longer it takes to start flowing freely and may cause low oil pressure on start up. Should be able to change big end bearings in situe tho. Although i never have. Just guessing.

I just dont see how big end bearings being worn would cause low oil pressure? But i may just be being stupid?
