I check my oil its good, so if its a bearing, do i need to get my whole engine rebuilt or can i just get it replaced..
IF it IS in fact a spun rod or main bearing, the crank will have to be at the very least polished, but most likely reground. If a main spun enough to damage a main journal, you may have to align-bore the block.

Are there metal filings in the oil?
