So guys,

Did an oil change on my cefiro, and found this in the drip tray when I was draining it. (tray was spotless before dropping oil)

The thing is, apart from a slight lifter tick on stone cold starts the car has zero engine knocks/noises. Can hear injectors over everything else.

50-60psi oil pressure straight on start up, warm oil pressure at idle of 20psi. When on the track copping a caining the oil pressure at idle sometimes drops to 10-15psi. (with the car idling at 500rpm)

Has been the same for the entire time I've had the car on the road. (almost 3 years)

Oil changes never past 5000km,

Always used motul 10-40w.

Next thought is that its something from the turbo, but again, no noises, still boosting fine. (hypergear highflow, never over 20psi, running supplied oil feed hose, stock drain.)

Yet to pull anything apart turbo wise, but am going to pull turbo oil drain off, and see if I can find any evidence, then check shaft play.

I assume the filter would be stopping most of it, but I really don't want shit like this floating around in the oil, plus want to fix the issue before it becomes bigger.

So, with that amount of metal in the pics above, if it's coming from an engine bearing, would you expect it to be knocking?

Anyone had a turbo fail and experience similar?

Have my RB20 days come to an end and now have the perfect excuse to go RB25det NEO? haha.

Same thing happened when I changed the oil in my Falcon the other day. I just through it in the she'll be right basket.

It still see's limiter daily and sounds fine but if you;re really worried get the oil tested or take it somewhere to have them listen for knock.

Looks like copper colored, it's amagnetic so a magnet won't do anything about them.

If you kept the old oil, you still can do an used oil analysis that will tell you what's going on but with the shape and color of the parts we see, it's most likely the bottom end which is going. :(

If you get rid of the oil you'll need to run the fresh oil for 3000 km before doing an oil analysis.

Yeah I've still got the old oil, unsure what an analysis would tell me, unless the thrust bearing is a different material to a big end bearing?

Couple of guys have suggested thrust bearing, will check endfloat this weekend. Still zero audible (by ear) noises.

Did check turbo, looks all ok.

Should just Yolo it, it is only an RB20, haha.

Cheers for the replys

    • Sorry to hear your HFM BM57 was faulty,  did you contact HFM I would hope they would be at least grateful for the information if there was some sort of manufacturing fault, you would hope they would be sympathetic even if your item was 2 years old if it had never been fitted. May I ask where it leaked from ?
    • Cats are called Bella, and Donna...  Like that poisonous plant And I remember your 2 monsters, I remember making a little bit of wee when you let them out... LOL I have already installed cat doors into the laundry where their kitty litter is, and the sun room, apart from the cat doors there's not going to be any permanent mounted stuff on the interior walls (interior doors are cheap and easy to replace) I will get a outdoor cat cage thingie once I finish the landscaping out back... https://catnip.com.au/ The only off limit areas are the main bedroom and the gym room....but, currently the cats are curled up in bed, in the main bedroom with the Mrs.....LOL, the off limits for the kittens to the main bedroom lasted about 5 minutes with Jackie I currently only have 1 free standing huge cat tree multiple level scratching post thingie in the lounge room, but, I will be getting another one soon now that I'm happy with the furniture layout in the back room and have a perfect spot for it  
    • All of this is making it seem clear that running the Coppermix twin was definitely the way to go, especially in hindsight with how insane tariffs have gotten and the strength of the USD vs yen at the time.
    • That sounds like no chance of even importing one for road registering then Now I see why Duncan wants to check LHD rules for Targa...   I wonder how "bolt in" the AWD would be if you got one imported from the US and swapped it to an AUD one
    • Not to mention they drive like a bucket of bolts! yuck!
