Yes! After only 87,000km and at least 12 oil changes my engine quit on me. I had the car towed to the local GM dealer, only to find out a few days later that the engine had sludge in both the upper and lower engine. I was also advised that GM would not warranty the engine because of the sludge. I bought this car thinking it would be much better than the usual GM product, because of the Toyota engine...but was I wrong! I am presently compliling several complaints from Toyota and Pontiac owners about this problem. It seems that Toyota have have had engine design flaws that contributed to the sludge problem (engine running to hot, oil filter positionning, etc..). I have most of my maintenance records and still GM does not want to cover the motor on warranty. If you have any other information about this problem, could you forward the info?

I had the valve cover off mine at 100K miles, definitely no sludge problem in there. Also, among the Vibers at forums.genvibe.com, there have not been any reported sludge problems
Only if you use poor oil and don't keep it clean.
Sludge in an engine is cause by poor maintenance. Air and contaminants build up over time to create a thick sludge throughout the engine.
This engine is known for having a sludge problem. Toyota extended the warranty for 7 years (total). I don't know if this caused your problem but you may want to look into reimbursement from Toyota if sludge was the cause.
Toyota's need to be serviced often.. otherwise they tend to turn their engine oil into sludge. this may be your problem.
Some sludge issues with this engine. Change the oil regularly.

Engine sludge is what the dealer told me Engine sludge is what the dealer told me
Flushing sludge from your engine is not a very smart thing to do. Almost every automotive technician will agree with that. Flushing out an engine causes all the sludge to drain down into the oil pan. Which in turn tends to plug up the oil pick up and causes engine damage.
one sing can says a lot: check in your oil cap, if you find some oil sludge, its a big revelation that you have oil sludge problem in the engine
any one help me please where we can use paint sludge? which industry want to use in system of production ? regards Thanks reply me faraz.scn@gmail.com faraz.shamim@toyota-indus.com
Engine sludge formation includes, lack of proper maintenance, inappropriate oil temperature, use of an inferior engine oil, and engine oil contamination. You can try flushing it out with an oil flush additive but often times this does more harm than good.
You don't mention what year it is. But i can tell you if it is between the years 1999 - 2003 you better do a search on Oil Sludge on Toyota's. You might be in store for a major engine failure. There was a class action suite on this and those years mentioned above had that symptom and the engine needed to be replaced. I am saying this because my 03 Rav4 had the oil light come on and then the check engine light. when i took it to the dealer, he said that there was sludge in the oil and that caused the lubrication not to be up to where it was supposed to be. With only 70,000 miles on it too! Their repair estimate was $6,061 for a used engine. And no, i have a good maint. record on the vehicle. A call to the dealer and to Toyota says there is nothing that is under any warranty to cover this. SO be careful.
