Metal bits in engine oil/filter. Cause?

[dball33]

I recently did an oil change a couple weeks ago and found little metal bits. I've been searching for a while but don't know what to search under besides "metal bits engine oil." Can someone tell me the cause of this so I can go search for it. Thanks

Do you let your car properly warm up before driving it? How often do you change your oil?

[dball33]

I let my car warm up for about 5 mins or when the idle goes below 1k before I drive it . I change my oil every 2k miles with Mobil 1.

Timing chain guides.

They get chewed up...kinda on a regular basis once their is wear, lots of folks just remove them.

Correct me if am wrong...it could be worse....like real worse..
