Going to replace my leaking valve cover gaskets soon and while watching videos it showed the oil lines to the valve covers have oil filters. They are cheap enough that I plan on replacing them and not cleaning them. I am curious what they look like after running Syn oil and better filters.
Toyota VVT oil filters, who knew?

They're more like screens than filters. Running decent oil & filters, for a reasonable OCI, I would think they would stay clean.
I agree they are screens more then filters. I am surprised they even worried about using them.
If these have no tears and look unblocked, leave alone.
Some Subaru turbo engines used them eons ago.

VVT solenoid screens are common. And yes, a screen is a filter.
And, with the typical US consumer, they clog often enough.

That’s why I said “when properly maintained”. My main experience is with the Corolla 1.8 in my sig, at 167K the VVT-i system is fine-but it’s had full synthetic (by me) since ~100K miles, so maybe it’s an outlier? My brother has also had a couple of pretty abused VTEC engines, an ‘01 Civic EX & his oil burning ‘01 Accord, and other than VTEC seal leaks/replacements, they’ve been fine. If Dorman makes/sells a replacement one, there has to be a demand somewhere.
