Found these in the oilpan

[Seth_O]

My truck is dumping fuel in the crankcase via the HH. I am waiting on new o-rings to take care of it, and in the meantime I drained the oil in preparation for replacing it all.

I drained ~13 GALLONS of liquid out of the oil pan (you can imagine the mess when my usual 5ga oil catch pan didn't catch it all.......) I also found some shards of metal in the oil.

I am dropping the pan tomorrow, aside from the crank and the bearings, anywhere else I should be looking? Or are these too small to worry about? These particular peices look.........unhealthy, to me.

Engine was running strong when I turned it off last, no strange sounds.

I would say any metal in the pan would be a very bad thing.

Kind of looks like bearing material to me. Best thing to do is drop the pan and start pulling caps and take a good look at the bearings and their journals. If your lucky you don't have any crank damage and can just roll new bearings in and be good. If any bearings have spun (which I suspect) the crank will have to be ground at the very least and you may have to have new rods and the block line bored.

When was the motor rebuilt?

They do look bearing like, is it possible they could be from a previous failure? Caught in a crook or cranny somewhere and migrated to the bottom of the pan after a rebuild?

What ever it is it doesn't look good. Looks to me like those pieces have what appear to be threads on them. Are they magnetic ?. Bearing material will not be.

That is a slight possibility. I've seen it before.


I can't tell from the pics for sure but it looks like waded up thin material rather than threads. Kind of like the material piled up on itself before coming out.

Looks like threaded material to me. Like the previous poster stated, See if they are magnetic. If they are, it could have been a bolt that got misplaced or dropped during a previous rebuild. No telling what damage it has caused until you start tearing the engine down. There is a good chanch you will find more someplace you don't want to see it.

 

[WillWagner]

Looks like extruded material, like a bushing/bearing. Cut the filters apart and lay the media out flat to see if there is more stuff in there. If there isn't, it's most likely from a prior failure. That sample is VERY small. It's most likely leftovers.

Will is correct, Cut your oil filters open and check for metal before you pull anything apart. Also see if its magnetic.

Definitely piled up material vs something threaded. Looks like something rotating shaved a small amount each rotation and it built up. I am picking up my air compressor today that I lent out so I can drop the oilpan.

Good call on the filters Will. I will cut them open to see what they show.

X2 on 'piled up' material. I'll bet you a box of donuts that they are leftovers from the original manufacture or a rebuild.

Pull the filters before you pull the pan. It will save you a ton of work.

I had a truck that was new to me and the engine ran great. during some much needed maintenance I had the filter cans off and found shavings in the filter base and filter. There were enough that I knew there was some trouble. I pulled the pan and found #5 rod bearing torn up and slight scoring on the crank. Funny thing is I never heard a knock until I put it back together to move the truck to a place i could pull the engine.

I ended up pulling the engine and put in a replacement. I hope you find nothing.

 

[Seth_O]

I pulled the oil filters today. The first thing I noticed were small metal shavings in the bottom of the filter well. I opened up the filters and found metal fragments in the filters themselves. Fragments did not respond to magnets.

After dropping the pan I took a good look at the crank - it looked pretty good to be honest, I didn't immediately see any problems. It made me start wondering if it was possible my oil pump ate itself. I dropped the first carrier (? - where the crank bearing sits) and the bearing looked good, nothing more than normal wear, crank looked really good. I pulled the 2nd carrier - and found scoring on the bearing and a small piece of metal chipped/missing from the bearing surface. The crank looked good however.

Pic's below. Looking for some thoughts on this. Based on what I see I think I likely need to pull all the bearings and inspect/replace them. The crank probably needs a good inspection as well.

I guess the real question is - do you think this means a full rebuild? If so, what do deuce rebuilds go for (compared to a regular engine - I know the total cost changes market-to-market.) I had an old landcruiser engine rebuilt several years ago and it ran me $2k+ .

 

[m16ty]

If your crank looks ok, You can put new bearings in without dissembling it further than you already have. The rods are self explanatory. On the mains, loosen all the caps so the crank drops down a little. Then take a soft object (you don't want to score the crank) and push the upper bearing out. Then you just spin the new one in it's place.

If you find out you need crank work, it would probably be cheaper to find a replacement engine.

 

[plym49]

Those marks look like damage caused by metal bits circulating through the oil system. The slight scratches on the crank journal(s) is insignificant. You can install new bearing shells as already stated by m16.

You should try to see where the particles came from. Check what you can get to while you are under there. It is still possible it is just swarf from some previous work.

 

[Clay James]

If you take off any of the rod bolts you'll need to put in new ones. I saw in previous threads about thrown rods it may have been from reusing old rod bolts that stress fractured and it was just a matter of time before they let go.

 

[fsearls92]

The old saying always comes to mind; If its not broke don't fix it. A rebuild will cost about the same either way, just postpone it until it gives out.

 

[diverman555]

One thing you can do is get a filter cutter, it cuts your filter open but does not allow for any of the cuttings to go into the filter. you can get the tool for fairly cheep. Also when you start pulling rod caps, make sure you number them so they go back in the same place, in the same direction. It does not look like bearing material to me either. so once the pan is pulled and caps, make sure you leave a couple in place, but get a really good light and look as much as possible up inside to see if something is wedged up inside. Check rod and main bolts.

 

[WillWagner]

Don't drop/loosen all the mains at the same time unless you want to be doing front and rear main seals. you can drop all down but 3 or 4, roll the new shell in, torque them up then do the last one. Take the belts off or just loosen them, it helps when doing #1 main Also, before you go and buy bearings, look at the rod that that main feeds to see if the rod bearing has failed and taken the crank with it.

 

[Monkeyboyarmy]

It looks like the main bearing with the thrust may have generated some heat. Looks like the crank has turned color. This could a surface heat treatment from the crank manufacturer but I would drop that main cap just to make sure.
