Default Re: cause found for engine sludge problem?

This is an interesting article:

It mentions that only the "Toyota or Lexus from model years 1997 to
2002 that use the 3.0-liter V6 engine, and any Toyota from 1997 to 2001
that uses the 2.2-liter four-cylinder engine" are affected by sludge.

It also mentions that "It's worth keeping in mind that, at least so
far, Toyota reports about 3,400 sludgy engines out of about 3.3 million
sold. So these are still excellent cars, in our opinion, and we'll
continue to recommend them."

That's about 0.1%, not the 10% I had envisioned in my mind.

So my question is, starting in 2002, are the 4-cylinder engines now
"safe", that is, are there any reported sludge problems with these
engines (assuming the engines have been properly maintained)?
