Metal In Oil, Yeeeew.

[CEF33Y]

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.

More than likely she is knocking, need to listen to the crank with something better than just your bare ears.

[CEF33Y]

As in knock ears? Or like a screwdriver/breaker bar from block to ear?

Has is plug ya headphones into the sump plug.

[CEF33Y]

Haha.

Im still blowing out, I did a 1100km round trip over the weekend (after the oil change) and it was running sweet.

Only drained the pan last night and went, wtf is this?

So there isn't much legs on the "maybe its just a turbo theory?"

[gtr jet]

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.

[CEF33Y]

Yeah, will investigate a bit further, cheers

[-S-]

Maybe use those magnet nuts to catch those metals to prevent further damage?

[R_34]

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.

[GTRPSI]

Check your crank end float, it may be just the thrust bearing if you don't hear rod knock.

[CEF33Y]

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

[ERO54N]

Pics looks like you were panning for gold.

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

Yep haha

[Dose Pipe Sutututu]

just rev bash it a few times at 8k, she'll be right.. #onlyarb20
