It sounds like this applies to the new 2002 ES300 as well.
I remember reading several weeks ago a report from an engineer or a ASE certified mechanic of what he thought was the technical problem with the engines in question regarding the so-called "sludge" issue. He stated that there was an engineering change in the engine starting with 1997. It might have had to do when they went to certify their engines for the low emissions standard. Does anyone remember that and maybe that person could repeat his explanation for the change in the engine design and explain it to us. Was there, in fact, an engine design change in 1997? If so, has that design been changed?
