Just got done with cab off HG, studs, Updates on my 05 80k miles. No issues with truck other then high coolant pressures before. Weird string of events happened ( 3rd day of driving WOT run sit at a light and low oil pressure warning comes on) go home put a mechanical gauge on truck and im reading bar not psi and think I have 5 psi not 74 psi like I really have (idiot). Pull oil filter housing and see non metallic particles in the bottom, still thinking I have a LPOP issue and bearing material in filter. Pull cab HPOP reservoir is pretty clean, IPR screen clean, oil pan is glittery, LPOP still can see all factory machine marks on everything 100% new, remove my mechanical gauge and see the outer black ring is in BAR not PSI. I feel better knowing engine had great oil pressure for 180'F T6 5-40 but still why did I strike gold. Pulled turbo apart and it looks new inside zero in - out movement and little side to side 30k miles on ford reman. Tried to measure oil clearances but I only have pins to check bushing ID and I have under .001 from shaft to ID. Im stumped and really don't want to pull rods, and drop crank to find nothing is wrong with this engine. I replaced pushrods with the shorter 6.4 rods and the copper coating that is on the tip looks a lot like whats in my engine, any chance this is what it is?

A lot of things are possible, to include your theory. Really, unless you do an oil analysis, there's no way to know what that is for certain. And, only with repeat analysis will you be able to know if it's a problem or the norm. Personally, I'd bolt her back up and continue on about my day.

The struggle is real. Do i throw it together and always wander if its going to last, or do a full tear down and throw a billet cam in it. With 80k miles and 15 miles on new HGs it does kill me to do a full tear down, also negates any good deals i got on the parts i purchased before.

Just pulled oil cooler and only thing i found was more copper looking deposits in the channel that feeds the turbo EOT & EOP sensors. Pulling the valve cover i remembered i used Fel-Pro gaskets and they have the little copper donuts around the push rods. Push rods look close but i cant tell without taking more apart if they are rubbing.

Why not try to collect as much of that as you can and send it off to Blackstone for an oil analysis? Will cost you 25 bucks, but you'll be able to know if it's copper, brass, or some coating on the HG or pushrods. That's a lot of peace of mind purchased for just 25 bucks.

This is the last two rod bearings upper and lower. Don't know if this has been going on for a long time or was a sudden issue. Shocked at 80k miles thought these bottom ends last a long time. Any ideas?

As long as the crank jornals look decent, i think i would check the mains, polish the rod jornals with fine cloth, put in a whole set of new rod bearings. one looks more like wear over some time? there could have been a temporary lack of lubrication but they dont look that bad. main thing is to find out why. oil pump ? replace it maybe, and hope for the best on the cam bearings. when you think you are ok on the oil pressure, start driving it and change the oil a few times and look for more metal. more metal.
way I see it you dont have that much to lose, I would take the gamble.

On second thought these bearings dont look like they are worn bad enough to make a lot of metal in the oil, the pictures don't give an idea of how much stuff is in the oil, so two bearing trashed, one looks like posibily long term wear, the other lack of oil. could be the cam bearings went, that could explaain a lot of metal. The mains especailly the thrust bearing part could have gone. Maybe you need to tear down the engine after all. it would be a judgement call based on how much metal versus the bearing appearance. Still there is the question, what happened. If you pulled the pan during the cab off, there could have been a short oil starvation till the pump got primed but other than that? the issue that caused this might remain, one bearing looks like possisbly a slightly bent rod, maybe. Anyway, good luck,

I agree not enough damage shown yet for whats in the pan and filter housing. Cam is coming out i had to build an engine stand first. When i did the HG i didn't touch anything other than the heads, pulled the pan after i found metal. Im confused this truck pulls our camper and i never found anything in the oil before. Also have not found any thing that i caused. No antifreeze in the oil, Oil pan was spotless other then the gold flake, LPOP was like new so its not like i sucked up crap, Everything was assembled as it should, crank end play .007. Truck ran great never lost power or smoked or did anything weird. Been really beating myself up on this one.

Did you send an oil sample off?

none of the bearings look that bad, but none look good either. signs of embedded stuff and uneven contact. the only other thing I can think of after the cam shaft is the HPOP. Yous has the better HPOP and is suposed not to fail. At least so far you appear to not need any major parts or work. if you get out of this with cam bearings an a cam shaft it is not bad, relatively speaking, of course.

Im not sending oil out, i don't really see any reason too. The cam is coming out and a colt is going in. I have had this truck 10 years and plan to keep it another 10. At that point the house is paid off and i can mortgage a new truck. I built a few gas engines and never seen bearings like this and at this mileage im even more confused. I will have to investigate the oil that comes out of the oil rails after the HPOP, seems the oil coming in was pretty clean. I will be taking the next day or two to clean up the barn and get ready for surgery.

cam is out and like all other bearings they have wear. Still do not have the root cause. LPOP looks like new, fresh t6 oil, pickup clear, ford oil filter with original cap, I did replace the check valve and bypass stem but nothing wrong was found with the originals, truck ran great.

Ordered all new bearings, colt stage2, lifters, all seals and gaskets, another OEM oil cooler, rod and balancer bolts, turbo rebuild.

Im going to pull the cluster to see if it has the resistor across the oil pressure gauge. If it does I can install a real pressure gauge so this never happens again.

It is the oil pressure sensor that is only a switch.

So what ya got is Babbitt material from a bearing somewhere. Bearings are usually copper underneath the surface material. And they're the only parts that have copper usually, so copper is kind of a dead giveaway. One of those pics up there clearly shows a bearing being eaten down to it. I'm guessing there's a few like that.

And check your oil clearances again. .001 isn't right, that's way to tight, especially for a diesel.

Could be lots of stuff. Since none of the mains look like that, it's probably not a viscosity issue.

I'd look very close at the rod for that cap and see if it's bent. It kinda looks like it's been side loading a little bit or something. But first get all the bearings out and look at them. Then determine the cause.

The oil cooler bypass valve plunger is brass. It is common for it to "wear down". That said, can't imagine it producing a lot, but worth looking at.

Regardless, the entire engine needs to be gone through, which it sounds like that's what he's doing already, I only read a couple posts though, so I don't know. There's various stages of rebuild. How far he takes it is up to him.

Technically he could just put a bearing in the one that's messed up and keep driving it. I might cut be inclined to do that if it were mine. It just depends.

Out of curiosity, do you run a 5 weight in this engine?

This won't help but it is something to think about. I bought a used Hyndai from a Hyndai dealer with about 30K it was a rental and presumably maintained. On my third oil change the oil was full of very fine metal, the dealer said it would not be a warranty issue tiil the engine blew up or something, well it didnt and the metal was mostly gone after the next oil change. My point is these things are not always a sign of an engine fixxing to blow. You may not find that answer and MAYBE? the truck could have withstood the damage that is sofar evident but your peace of mind is imortant. I my case the car was never going to be a long term drive.
