#98 of 108 Regarding sludge by trendao

Regarding sludge, the only thing I've noticed is in my oil fill cap I see some slight reddish brown pasty gel. The engine probably burns about 1/2 to 1 quart per 5000 mi. So, just to be on the safe side, I've just started adding a dose of Seafoam(r) additive to the crankcase to keep the internals clean. The gel is not as noticeable as it was before.

I would try using synthetic oil and/or shortening the oil change interval.

I've had my 2008 Sienna LE since for five years now. Always had it maintained at the dealer around my way. I've got 107,000 miles on it, and recently had the VSC, TRAC Off and the check engine lights come on. Took it to the dealer and they mentioend that there is a a service bulletin for this problem: TSB0094-09.
 
They want to charge over $5,400 to fix this problem. I don't understand it. I've paid $close to $31,000 for this car the past five years. If I've done everything right, then why should I have to pay this large an amount to fix something that Toyota knew was a problem.
 
I've opened up a case with Toyota, and hoping they will help. I'm already in the market for a new car, but if the new Toyota's are built in a way that you have to have a major repair done on them after 107,000 miles, then they are just not worth it.

#102 of 108 Oil Leak on 2012 with 5k miles by rwolf1

I took my 2012 Sienna in for a fluid leak. To my surprise it was an oil leak coming from the top part of the engine. They decided to replace the block and the two cylinder heads due to oil leak between the head and the block. They reported that the leak may have been caused by potential damage during engine assembly.
 
Has anybody else had problems with oil leaks like this? Especially on a Sienna with such low mileage. Should I be concerned with having them replace the block and cylinder heads and re-using all of the other parts from the original engine. they put in a new crankshaft and pistons. However, they reused the valves and other parts.
 
I feel like I own a new vehicle with a rebuilt engine!!! Should I be concerned that they have gone into the engine this deep? I have a concern that they have done so much work under the hood that there will more chances for problems in the future. We are the type of people to buy and hold our cars. We currently have a 12 year old Sienna.
 
Concerned Toyota owner...

Only 2GR rebuild I've seen here...
 
Ask for a 100k warranty on the powertrain. Seems reasonable to me.
 
A friend got a new trans on her Ford and they did that for her (for free).

I got a 2011 Toyota Sienna SE and had an engine leak at 15,000 and they tried to fix it twice but did not. They just ordered me a new block.

I agree with you, Toyota just does not care, I have had the same problem from Toyota that they just say that is the way it is. Mine is a problem of piston slap. They still sell lots of cars so its a matter of getting the word out that their product is not as good as it was in the past and their customer service is a customer diservice. Good luck with your problem and for me too, my Toyota Sienna 2010 is the last Toyota I buy and so far I have dicouraged
6 friends to buy another make.

Yes I have the same problem.
I have a 2010 Sienna and it now has 75,000 miles on it. At 5,000 miles it developed this noice of loud clicking when engine is cold. Toyota Headquarters USA says its Piston Slap and that it is normal. In other words if its normal then they must design it to be this way. The designers of Toyota do not seem very bright to me if you make a engine with Piston slap problems. This is the last Toyota I buy.
