"2914 of 2919 Sienna Sludge? by cmh707 Apr 23, 2004 (12:16 am)
I am contemplating buying a Sienna, and was wondering if they still have problems with sludge buildup?"
Are you planning on buying new or an older model? The 2004 had an engine redesign and I have not heard of any sludge problems. The 1998 - 2002 are the models covered under the 8-year unlimited mileage Toyota Sludge Policy. Many people blame the problem on owner's following the oil change recommendations in their manuals (5,000 miles severe/7500 miles normal) and state these engines need 3,000 mile oil changes to avoid an early demise.

From what I understand the 03 portion of the TSB refers to a 2003 TSB. So is this a new one or do we wait for the summer when Toyota had at one time stated they were coming out with a fix for the brakes?

In regards to changing oil - the manual also states to change the oil within a certain number of months also. I have not seen one documented (proof of oil changes and the date/mileage service was performed at)case where the user followed the maintenance schedule with regards to mileage as time and still had sludge problems.
I know this issue has been beat to death, so I don't want to get into it again, but if anyone can point me to a site where this is documented, I'd love to see it....

fix TSB that was to be issued for this summer? I guess I'm confused as to why an '03 TSB was issued in 2004!

I had my rear drums replaced,and are now silent, but now my front brakes are squealing, and only in reverse. What is going on here...

Are the pads worn out? Maybe the wear indicator is notifying you that they need attention.
#2928 of 3687 rear drums replaced per TSB

Drums were replaced today. My 2003 sienna had 10k when I first noticed squel from brakes. Suprisingly I told them I'm aware of TSB (through this site, thanks) and they said how I knew, I said through friend, and w/o any BS from them they did it. Like in the earlier post, I noticed they grabbed better, less slack when i apply parking brake too.

Not sure where you read that the TSB was issued in 2004. The one I mentioned was issued Nov 2003. I guess it just takes time for the news to spread, so by the time some of us get it fixed under the TSB, it is already 2004.
