loose rod cap bolt J70TLEOR

[fishfeatures]

I picked up a 1995 70 hp for what I thought was cheap, as I needed to replace my other 70hp beacuase I had no T&T. Guy was selling it due to damaged harness, some of the grounds had melted (looked worse than it was). After fixing the wiring, I was quite surprised to find that the motor started first turn. However I heard a distinct knocking, so I shut it off and went to do comp test (110 70 110). I'm just after tearing down the motor and there is a loose rod cap bolt on the #2 con rod.
Seems like the #2 rod was replaced, as its a different color than the other two.
Walls seem good I can still see crosshatching on 2 of them except on #2, so I'm just wondering would this loose bolt cause the lack of compression ??

Not at all.-----Measure the # 2 bore and post the diameter.

I went further there now and the bearing under the cap is shot ...... looks like it wore into the journal. Is my crank toast now or cam it be fixed somehow
