Pics of internal damage.. Need advice.

So over the past week I have been breaking down this EJ205 one rusty bolt at a time and removed the oil pan today and found this.

Was afraid of seeing this so I removed the oil splash cover and took a peek inside the block and found this. Not sure it this is normal wear or abnormal wear.

I didn't get a chance to get the heads off yet had a helluva time trying to get the cam bolts free, but with luck for once I got all 4 loose.

I removed the intake and exhaust cams from the driver side today and started tackling the head bolts, 2 broken ratchet extensions later I decided to call it a day.

So with the amount of metal in the bottom of the oil pan how bad do think the damage is inside the block?

It's hard to see what it is in the pictures. Are there metal filings in the bottom of the oil pan?

Yeah I scraped the pan with a magnet and its definitely metal.
I removed the heads today and from the looks of it the head gaskets went as well.

I'll post up pics of pistons and valves when I get on my laptop.

When I removed the one head bolt there was a bunch of goop on the bolt threads "guessing a combination of oil,gas,coolant mixed" can't really describe the smell of it other than crud smelling.
I believe it was the bottom right bolt. And the one head bolt on the bottom middle had sand or something on the end of the threads?
The spark plug was also soaked in the crud stuff as well.

The side that had the knocking noise "driver side" was the cleaner side.
And the passenger side was the mess with the crud.

any input for this?

I had the same issue on two different outback that I bought. I ended up tearing the entire block apart and found a spun rod bearing and it destroyed the crankshaft journal, hopefully not your case. the head gaskets started leaking causing water to get into the oil and took out the bearings.

To me it looks like the crank shaft counter weight has been rubbing against the block, which isn't a good thing. I'm not an expert yet, but I think the bottom end is pretty much no good at that point. Hopefully someone else will chime in with more knowledge than me. I think the crank shaft seats are worn allowing the crank to move lightly forward and back which could be causing that rubbing we are seeing. Just a guess though! please let us know what you found!

My stomache turned into a knot looking at those last few pictures of your first post. Ouch!

I am far from an expert on any of it but I can't see how that crack isn't a death sentence to the bottom end.

I actually don't think that the block is cracked. those marks are where the two half's of the block mate together and possibly excess sealer and usually the factory machines the block where the counter balances rotate to give a little more room for excess crankshaft end play. I have three blocks torn apart in my shop and they all have the same markings like in the pictures. once you tear the block apart you will probably find the bearing have spun, that's usually a common thing with the metal you found in the pan

Pictures 3 and 4 definitely show that seam as normal but picture 5? Maybe it's an optical illusion of depth in that shot?
