Some side to side play is acceptable but that seems excessive. Can you possibly try to move the caps up and down? That will simulate the motion of the rod and give you a better idea of the play on those rod journals.

There was actually a small amount of sludge in the oil pan, (bit less than a handful). Did not see any metal shavings or big pieces. I can get a picture tomorrow, too dark right now and I forgot to take pictures. Makes me think that the sludge buildup probably messed with lubrication.

When you check the pan tomorrow use a magnet and see if any particles in the sludge stick to it......

I actually dragged a magnet through and there weren't any noticeable particles sticking to it. Nothing shining in the light as well. Other than the sludge, the oil looks ok.

Yeah I didn't really pay attention when I bought it, even looking in the oil cap you can see a small amount of dark sludge. I wanted to swap it down the road anyway since its a '99, didn't expect it to happen so soon though! Oh well, time to make it better.

I listen to your video u have a serious problem its a rod noise maybe #2 or #3. Iwould stop driving the car at this time and get it repair asap. Ance you get a good guy they can rebuild that engine to run like new. Hopefully the crank is not damage.

That's a bummer. Luckily my GE had a pretty new water pump, ps pump, timing belt tensioner, belts, radiator and only 127k miles on the chassis. Will save some money swapping the parts over.
