I have a 2002 Chevy impala 3.8l v6. I need to know what are the best choices for rod bearings. I see standard, .o20, .030, ,01. Not sure
What you are seeing are under sizes for bearings available for when the crankshaft is ground
you have to measure the journals with a micrometer to see it it is standard size or has been ground
or if you are just putting new bearings in during a quick engine rebuild then the bearing size will be stamped on the back of the shell
it will be either std or the .010" etc and you need the bearings with that size on them
anything else but std on a std crank journal will jam the shaft up--or .010" means that the crank has been ground .010" and needs bearings of that size
conversely if you put std shells on a .030" ground shaft , the bearings will flog out and oil pressure will be low to non existant
