I've challenged ANYONE to provide proof that the Toyota sludge problem was anything but owner neglect. NO ONE has EVER provided proof that a properly maintained Toyota has developed sludge....
Just to refresh my memory I corresponded with someone I trust completely in this manner. He asked that I not identify him and I won't.
I clipped some B/S that 'Mike Hunt' posted and asked my friend to comment on 'mikes' statements.
Below is the email I received ....

OK Scott, here goes.

My friends answer
No TSB's regarding any head change. I have not been advise of any changes. But I do know the valve cover is different, as the PCV valve screws in instead of popping into a rubber grommet. In August of 03, there was 2 engine available, ie the 3.3 or 5MZFE, and the 3.0 or the
1MZFE.
No switch to synthetics until 2007 model years, then they went and changed the viscosity also, ie now its 0W20 and its ONLY synthetics, but this just happened with the introduction of the 07 models. All oil change intervals have been set at 5000 miles, regardless of type of service

My friend's response
Never any recall on the 1MZFE Camry, they did extend the warranty to 8 yrs or 100,000 miles. That's it. Many of those are expired now. They did this from 97-01 models. There was never a problem with the head. I think they increased ventilation. But to date, I have yet, to ever see one that had 5K intervals. All sludged engines had a big void int he intervals. We really don't see any of these anymore. We did a few at first, then it was slow and spotty. Now hardly anything comes through.
