How do you check for debris?

At oil change, with a sieve on removed oil? With a flashlight to see if there is any shining particle? With an oi test? Any other way?

 

All the above. Good luck.

 

Getting my 15k mile service tomorrow pulling my 20k Toyota Care oil change forward to include an oil sample for Blackstone Labs. I'm not doing any DYI service or mods until I am certain beyond a reasonable doubt that my engine is healthy. No one has touched a bolt on the truck besides the dealer at this point. I have a 2/23 production date sticker but not currently on the recall list. I'll post the results when I get them back from Blackstone.

 

I guess if you really wanted to get a good look. You could take the pan off and check the little bowl dimple areas that could possibly hold metal.
