Glitter in oil

[WItoTX]

Admittedly I didn't read every post. But...what oil was in the car? It's discussed in depth on many other posts, Castrol runs ZDPP in its oil, as do others. I think the glitter you see is an additive, may e not ZDPP, but something else. The reason you don't see it on a normal oil change is most folks don't change oil until it's black. Since you just bought the car, I'm betting you are seeing an additive in the oil because the oil is still translucent.

I see that glitter in my oil all the time (I change oil basically ever track event). The oil still is relatively clear, and it's easy to pick the glitter up. The glitter isn't abrasive, or magnetic. Oil analysis doesn't show any excess metals in the oil, and no analysis has said there is anything to worry about.

I'm into this thread because I'm learning a lot about pulling off the oil pan. Thanks for all the posts! Very informative.

The additive was my bet early in this thread as I posted. I am also finding his work incredible and am watching this like a movie, LOL....

No worries a lot to read now that this has grown thanks the valuable input for you all

I can only speculate that the oil in the car when I bought was motorcraft since the CARFAX had an oil service last year in June about 2000 mi ago.

So curious with the mains being displayed in the above threads by OP, what is the consensus on the visible wear?

 

[furdfan2018]

I don like the looks of #5.. that deep wear mark in the center of the bearing is odd. Also... the thrust sides of the bearing don't look good. Visible bronze material showing and im wondering if that is what is being shown in the oil.

OP, what clutch is in this car?

As far as I know factory clutch

All things considered with the mass of the flywheel, clutch assembly and the constant clutch engagement/disengagement IMO #5 looks normal for 60k.

can you help me understand how the flywheel, and clutch assembly contribute to wear on that last main bearing?

Centrifugal force at the PTO crank end plus the 180° crank explosive downward force from the power stroke. We might add a hypothetical that the bearing may be just a touch different thickness in that localized burnished area.
That’s my unprofessional opinion.

 

[DFERA]

should I see about replacing that bearing?

There’s a difference between wear vs. burnishing.
Being you’ve sidestepped the Footnote to the ARP instructions the 60k burnished bearings may be a blessing.

There is a thrust pad on that bearing that eats the lateral force on the crank and rotating assembly when you push in the clutch. Most all engines have a main bearing with this feature for this reason.

As you can see, no other main bearings have this "face" or thrust pad.

That "thrust" main bearing typically should not look that worn.

Read the back of the bearings...my guess is they are all STD as the engine "appears" to be untouched prior to you doing your work.

If it was me, I'd be replacing all of them since youre in there.
