Just information, but my 1mz 2001 has 135k on it, no sludge, oil stays clear between changes, doesn't use any, gets changed every 3k with filter.
The secret to success with any Toyota is to use full synthetic oil, my choice is Mobil I, and to change it every 3k miles. It has worked so far with me, and my Sienna goes like a scalded cat and you can't hear it run inside the car.
If you're going to spend the price of a Sienna, mine was $25k back in '01, it makes sense to buy the best oil to keep it alive. Going cheap on maintenance has a very poor payoff.

I would get another opinion--while your vintage of Toyota is sludge-prone, changing the oil every 5k with Mobil I should prevent it. I think you were given the old 'here comes a woman, let's sell her some expensive work" routine. Have Hubby take it to a AAA top shop near you, for example. It's a terrible practice, the scamming of female customers, but it's been going on for a very long time, unfortunately.
If you find out it isn't sludge, contact the better business bureau about the Toyota dealer you dealt with that had no record of working on your car. That's garbage.
Check out my post #8, where I brag about my 2001 with 135K, using the same oil.

thank you for the replies - my husband was with me when we took it to toyota - when he drove it home, it makes a terrible knocking noise - he says it is because the oil isn't getting to the pistons. we have a mechanic friend who is going to take a look but i am pretty sure the sludge has destroyed the engine - we have been doing the mobil 1 oil changes every 5K so I am not sure why this happened to my engine - is it worth it to replace it (we have been looking for a new engine online, and the mechanic can get one direct from his source as well) but with a 10 year old car should I put the money in? (can't afford new right now - had hoped this would last to 200K miles -I have always had great luck with toyotas until this one) - just had new brakes and everything else runs great. thanks

In that case I'm not surprised at all - synthetics are much more resistant to sludge and flow better after a bunch of miles.
