What would be the proper way to determine if the oil pump gears need replacing ? It was determined from my other post the oil pump is a Melling 45.

Mine has 6 thousands or so of space between the oil pump gears. Would that much space cause the engine to have low running oil pressure ( Hot engine ) ?

The engine is out of the truck and I think this might be a good time to address any potential issues.

Thanks in advance. Michael...
