Replace bearings or not? I was able to pick up a low mileage 15,000 mile long block from a very trusted friend. The motor has been dissassembled for the past 2 or 3 years just waiting for a build up project. I recently through a rod so I went ahead and just bought the long block from him. It already has a fresh hone and all components were checked for roundess. Here are my questions...
Do I need to replace the main bearings if they look fine?
Do I need to replace the rod bearings if they look fine?
Given that I can reuse the bearings is simply checking bearing clearances and using a plastigage ok?
Other than the typical you might as well while your there response are there any legit reasons as to why the bearings should not be reused?
I plan on replacing rings because I know how they can get after sitting for a while so I plan on running stock gapping with most likely a Total Seal moly ring set but I figured I could save $180 for something else if I really didn't have to reuse the bearings. I'm assuming cam bearings were done with block work also which is why they were not mentioned.

Any way you could make me a drawing with paint on how to use a dial indicator to check them. I've used the indicator when setting up rear ends before so I know how it works and the one I use is magnetic. I just can't picture how you would check bearing clearance with one.
its kinda a pain in the *** to do compared to using a Plastigage but its alot more accurate IMO im gonna attach an article, about half way down is a better explanation than i could ever give lol look up dial indicator bearings clearance on yahoo and google and itll give you more info than you ever wanted to know.
