Sludge!
 Beware of Toyota Sienna 1998 and on. 
Engine Oil Sludge problem just 
recently acknowledged (7/02). Lots of 
warning lights leads to many wild 
goose chases searching for perhaps non-
existent problems and spending lots of 
money in the meantime...stick to a 
Honda if you're going to buy a mini-
van, post 1999.
