2018 Panigale V4S bits of gold in oil, some questions on next steps

Hello,

I apologize as I'm sure that some of these topics have come up and have threads, but I was unable to find them searching various terms and phrases earlier.
I just purchased a used 2018 Panigale V4S with 11400 miles on it. The bike looked OK for the most part, a little dirty by the chain and swingarm pivot, a few small paint chips and clear blemishes. Started up and ran fine and didn't have any errors lights or anything showing during a brief test ride. So I went ahead and purchased it. The bike had been hardly used the last two years and was stored in a enclosed shed according to the owner. The oil level in the sight glass was at the right level but really dark.
First thing I do when I get it home is drain the oil and put some fresh in (although I did not do the filter yet, I was just putting fresh in to flush the system a little before doing a full change with filter). When I was transferring the oil to my larger container I thought I saw a quick glimpse of a gold or bronze colored fleck. Today I drained the oil I put in yesterday to examine it more thoroughly. This oil has only been in the bike for 24 hours and all I've done is idle the engine for around 30 minutes total with some small 5k revs here and there.
I did notice more small gold flecks in this oil (mostly likely still left over from not doing the filter and that small amount of oil not being drained), so now I'm going down the rabbit hole of bottom end bearings failing. This time I pulled the filter out also, I don't see any in the filter medium, but did notice a few specs on the oil filter cover bottom.

So to get to my questions.
What is the failure mode for this if it is bottom end bearing while riding? Will I loose oil pressure and engine go limp mode? Could it seize while riding presenting a large safety hazard?
I'm wondering if it safe to ride for around 500 miles and re-examine the oil after that. Basically can I continue to ride the bike safely and monitor without the potential for a catastrophic failure.

The other questions are related to engine rebuild or engine replacement.

If I got another V4 engine (ebay, etc), would it be swappable as is, or would I need the ECU and any other bits? I found some threads but they seemed about going from a V4 to a V4r.

Finally the rebuild questions. Are there any known places that are good for rebuilding V4 engines I could get a quote from, or is it just call around to dealerships? Rebuild related, do the V4s take many special tools to rebuild like Ducatis of old, or are they more similar to tools most shops that do engine work would have now?
 
V4 failures seem very rare. I lost a 1299 motor due to bottom end baring failure. My oil pan was covered in gold speckles...

To get into engine your gonna have to have the case split and completely opened up. you are looking at 2-3K in labor, plus parts. It will be expensive.

I'm afraid in your position, i would pay a master Ducati tech to rip it apart and take pictures and provide qoute for repair...at that point you either part out or fix it.

Good luck,
JAG

You will notice the vibrations get so bad you’ll feel it in your teeth. That’s what happened when mine failed. Prior to that I had zero warning for thousands of miles.
 
So what I have going on is no where near the volume shown in your picture SirJag. There are gold flecks floating around in there. If I had to guess a count I'd say 20 to 30 flecks seen. But yours is post total failure. I'm worried mine is beginning signs of it.

Send the oil out to Blackstone after a couple thousand miles?
 
First thing what does it feel like between your fingers. Does it feel metallic? And is it actually copper colored (I can't tell from the pictures)? Only one source for copper in the oil and that be rod or main bearings.

Good picture. I agree with your assessment. Get a good look at it and if it’s really gold, (feel it as well as bagger says) and if metallic, I think you need to get the motor inspected.
 
If it's copper don't bother with an inspection. If you want to verify the condition of the lower end the easiest way is to put a real oil pressure gauge on the engine, warm it up to operating temp and just observe the idle oil pressure. By the time you're seeing copper in the oil the idle oil pressure is usually a tell. I would recommend that you not ride it until you're sure that it's just clutch material. These will put a rod thru the cases. And since I'm in the midst of one that expired at about 14K with these longevity just depends. I hope it's ok but even if it is I'd go to a latter rev oil pump. I think the 25 revision going to the latest rev of the R oil pumps was the 4th Pani oil pump rev. About $700 I think.

Thanks for the response. My friend that has a lot of mechanical experience (just not Ducatis) mentioned doing the oil pressure gauge and check it against the manufacturers specs. Would you know off the top of your head what I would need to do this and where the access is that I would connect it to on the engine?
 
Is it not strange to see nothing particularly evident in the oil filter?

I agree. But the scavenge screens catch most of the bearing failure swarf. i should have taken a picture of the one I have. The scavenge screen was completely clogged. So almost all, except the stuff that will pass thru the screen early on, remains in the crankcase.

The oil pressure sensor of my SFV4 is on the end of a tube on the right near the ABS pump. The sensor will have pipe threads on the end so figure out the size and then the easier thing to do is go to one of the online hot rod parts suppliers and buy the parts. Just need whatever pipe thread to 1/8 tube and a cheap oil pressure gauge. These due to how high they spin have a lot of oil pressure, so hot idle should be like 30-40 lbs. But look the spec up. Oil pressure disappears with load if you have a real problem. The last thing you want to do is find a low pressure problem under load.
 
When my bearing failed, i had about 25seconds of part throttle before the oil light came on...

I mean it really possible I don't know how to properly assess the filter. I looked inside and around the exterior. I'll try to cut the outside off tonight and see what the inside of the filter medium looks like.

let it sit on that paper towel overnight...then next day use razor to cut around the whole thing just under the metal caps on the ends. then force the metal caps upwards and pull the filter media straight. Then youll be able to see what was caught.

i cant remember if the filter sucks from center, or pushes oil from center....anyone know offhand?

Outside in. To the oil cooler first then the filter. The oil volume runs up a galley from the center of the filter cavity. The oil volume is split at the top of sump case, one galley going to the rods and one the mains. So the mains and rods are fed from separate galleys simultaneously not serially to the rods as in some designs. Heads are fed from the end of the main galley (last). I like the design. This is the original filter? Looks ok to me but cut it open and spread it out as JAG suggests.

Inside (pic 1) was pretty clear of anything, outside had some swarf and debri that was deeper down in the folds and seen when spread out, but none that looked like golden color like copper, etc.

Pics do look good. Take with a grain of salt but I reckon for your peace of mind do the oil pressure test like baggerman said and if it doesn't show anything abnormal just run it. Check again in a short period of running.
