Thread dredge. Interesting that the videos are now "Private".

Apparently, SLUDGE makes sticky oil-control rings... which normally (now) don't scrape as hard as they used to... all in the name of "efficiency" from Lo-FRiction.

I have a more than nagging feeling that PO's ServiceMan had used synthetic oils, and drove like the Little Old Lady she indeed was....between home and The Shops.

Very common problem for Camry engines, - loads of sludge build-up.

Serviced every 10,000Km,or sooner?
