Visual reminder to oil change during break in (at 1000 miles)

[Joey_Midnight]

Dropped the oil at the 1000 mile mark to flush out the expected metal particles and will be repeating it at 2500 and 5000.

This is completely normal for all new and rebuilt engines so nothing is abnormal here for people that arent familiar its a visual representation to remind you how dirty they really are.

Change the oil at your own discretion, this is only my experience, some may find some fine dust, some may not and some may just complain because this is the internet and they spent $25 on oil for their 55k truck of their own free will and want to cause debates.

Not quite getting the second pic, can you explain?

Look at all the little flecks in the oil and on the glove.

Lots of tiny metal particles and little pieces of sealant, etc.

In General, junk that comes out of a new engine.

Do not run 10k miles without changing the oil.

Do you have the part number for the oil filter and oil capacity ? I'm going to get one ASAP and change ours.

Not intending to be sarcastic but you could look in your owners manual.

I'm at work right now, my wife is also at work with the 4Runner. I work at a shop just trying to get it order today.

OEM oil filter part number is 90915-YZZN1
Oil capacity is 5.9 qarts

Thank you

Exactly as cuttingedgesport said, the 2nd picture shows the old oil filled with metal particles and sealant bits when on a clean engine it would be a pure glossy brown without the metallic effect.

Is this showing Toyota still has the "engine metal debris from assembly" issue, but these metal flecks would be blocked by the filter? Or is this level of debris that's visible to the naked eye no worse or better than any brand new engine (i.e. they don't flush the engine and all the oil passages before they assemble them so some particles will end up in the pan upon the first flow of oil), regardless of the manufacturer (and still blocked by the filter)?

Also wanted to add that many dealers these days use a vacuum extractor to pull oil out from the top when doing oil changes. I wonder how well that gets these particles out compared to a bottom, gravity-drain of the pan? I guess it depends if the particles are mostly suspended in the oil in the pan, or if they sink to the bottom.

I can see the bits in the first pic on the oily glove. I just cannot understand the second pic. I get the topic and understand the importance of early oil changes. My issue is the picture, I don;t know what is in the frame. Looks like molten reflective metal, a lot of it. I see a brick house in the background. The orientation is bizarre.

Why isn’t the oil filter filtering these out? They don’t look too big to settle out.

right... I'm confused... Does the oil filter not filter these particles out?

WAW! i've done that to a 1600 vw motor way back then and do recall "stuff" in the oil.
I did not expect that much on a modern engine. I was planning on doing the similar interval you mentioned, but now seeing this it's imperative to not miss it!
Thanks for sharing!

It does, and so does a pickup screen. All that "stuff" stays in the pan. On startup, Oil goes from pan to pump, filter then everywhere else. So all that debris is "collected" as the oil circulates and ends up in the pan but will not go past the filter again.
Hope that makes sense.
