Replying to: 03sienna (Mar 04, 2009 4:26 pm) Not to scare you but your problem may be engine "oil gel" or sludge related. I also had my check engine light on in my 2000 Sienna for over 2 years and all they ever said was to tighten my gas cap. Now, this past November 2008, my car started to smoke in the mornings when I would first crank it. You need to go to www.oilgelsettlement.com and read it over. Also, there is a petition that other Toyota owners are signing on line. I can't remember the web address but if you google oil gel/sludge petition you will find it. Feel free to write me back if you need any advice. I just noticed that your Sienna is a 2003. Your engine may not have the same problem as the 1 MZ FE that was affected in the settlement. Good Luck!

When I brought it in they said it was leaking emmissons at the cap, and 3 other places. They would not guarrentee the $1000.00 repair would fix the problem.   I did not believe they knew what the problem was, because why would it leak all over the place. It should have been only one location. It was apparent they were trying to get me to repair things that did not need repair.   We traded the van in but if it were the oil sludge issue. I would have still been covered under the toyota extended warranty for sludge which is 100k I think. Would have been nice to know this could have been the problem all along.   Now that I think about it I am pretty sure a sludge issue would also have caused stalling. But the van would work fine most of the time. Just have that dumb engine light on. Replies to this message: ateixeira (Mar 12, 2009 10:35 am)
