Gasoline Engine Problems of Toyota Avalon

I bought my vehicle brand new and have had continuing trouble with what I believe to be the fuel system. Upon acceleration the car will periodically (daily) sound like it is running on diesel fuel or as if water is mixed with the gasoline. I have taken the car back to the dealer on 4 different occasions, and they have not been able to recreate the noise and, therefore, claim they cannot fix the problem.

Anytime vehicle is started up massive amounts of white smoke comes out from rear for as long as 3 minutes, and vehicle runs hard. Dealer stated it was neglect, not getting enough oil changes. Vehicle needed a total of 6 oil changes, and consumer had only gotten 5 oil changes. Valve cap was removed, and black sludge had build up. Dealer's remedy was to flush the engine, which made it worse.

While traveling about 35-40 mph oil light kept coming on and off. Engine stopped running. There were no prior warnings or noises or smell before engine locked up. Consumer had asked the mechanic for the old engine because it needed replaced, later the service manager told the consumer that the original engine could not go to the vehicle's owner.
