Install a $25 mechanical oil pressure gage and run it. Maybe run it with the valve cover off for a bit to see if the valve train is getting oil?

Yeah and if that hole in the bearing is not lined up with the oil passage in the block there there can't be much (if any) oil flowing through.
Could the fuel pump breaking hit that and damaged it? That’s a tough call but I think I’d leave it too and monitor it for noise and pressure and check for bits in the oil when doing maybe slightly more frequent oil changes.

I can’t simply tap it back inward either right? God damn.
Which one is it? Looks like the 3rd one back supplies oil to the valve train. If it's one of the other ones it looks like that particular bearing only will be affected. Might run forever or might not.

Yeah 3rd unless I’m looking at it wrong. Guess it’s time to get the VC off and see how it all looks.

My friend is right. It’s walked outward. I shouldn’t be able to see the edge of that hole. Crazy but could I get a brass rod and try to tap it like a race back in place?
And that’s why I’ve smelled oil. It’s drying up top and I could smell it. Piss.

Hard to say for sure, but those bearings don't really walk. They can spin though, and that's what likely happened. Honestly the best course will be to pull the motor and do this work on a stand, where it will be fairly easy. The bearing set is cheap and a new cam is $200 or so. I agree on the machine shop to set and hone the new bearings.
One other thought-It isn't that hard to find a spare running 2F. Install that while you work on this one.

I’ll see how the rocker assembly looks. Going to get kiddo now so who knows but I’ll give it a shot later today.

Damn what bummer, look at some cam diagrams and be sure the exposed bearing hole is indexed to the cam oiling hole, if it is
i'd try tapping it back in place with a brass hammer or drift what the worst that can happen. If it does walk out completely catastrophic failure is highly likely. There's only one way to fix it properly and that's a good bit of work and pushing a "While I'm at it" rebuild. How many miles on this motor? Best of luck with it.

Dammit. Even if I tried tapping it in place I don’t know if the holes are lined up. This sucks.

My first response. Well duh.didn't you have a bent pushrod when you did your top end job?
does look like the bearing has moved out of where it should be...and you could have oil starvage at the top.....
Yes I had a bent rod. I replaced it. Now I’m trying to visualize the movement of the camshaft ect. Bearings should stay where they were pressed so how would it spin outward?

It's just a press fit, and if it starts to spin, even slowly, it reduces the diameter until it's small enough to spin fairly easily. I think if you tapped it back in the hole, it would do the exact same thing again.
Interesting about the bent pushrod. I helped fix an FJ62 with the exact same issue and we ended up replacing the cam/bearings/lifters without doing a full rebuild and that truck is still running today. We did send the head out for a valve grind and guides though.
I'm trying to figure out how the metai got in hole in the bearing in the first place? Had to come from the oil passage. You have a screen on the oil pickup and a filter after that.
I think if we're talking chicken or the egg - did the metal get there first somehow and drag enough to spin the bearing? You said it moved when the cam was spun. So is the cam journal scored up which spun the bearing? Damn.

I agree with what these guys are saying.
Do you have a friend who you can borrow a cherry picker and engine stand?
I was able to pull my camshaft without pulling the engine but it would be easier and not much more work to pull the engine if you have the cherry picker and engine stand.

Yes. Bearing it out of its bore. The piece of metal is likely bearing. It’s good that it’s not spinning though. At this point only the cam is damaged and maybe not the block.
You can drive it as is and look for a donor engine. Or fix it the wrong way - I’d probably attempt the latter...

I wouldn’t think tapping it back in is an option.
Assuming the engine has never been apart and is still using standard bearings my idea of the wrong way would be something along the lines of - pull the grill, fan, rad, etc and open the timing cover. Pull the pushrods and lifters, pull the cam. Get the offending bearing out and replace just the one bearing. Make sure the cam journal is in spec. If it’s not find a donor cam and lifters... slap it back together and hope for the best.
It will take a few bananas, but you can do it.
Now que the folks who will point out this is a bad idea
