The engines in 1999 Sienna vans are possibly having early failure of the crankecase ventilation system that causes oil to sludge up and the engine begins to burn oil at a very early age. I recently de-sludged my van's engine and noted that the crankecase vent baffles are very narrow and had likley been stopped up for a long time. From the amount of postings on the internet about this problem this is not an isolated problem with this model.
