Tonight CBS2NewYork had a story on the 11pm news about sludged motors. It started with video tape of a mechanic scraping sludge from the internals of a disassembled motor. It looked like it was 1/4" thick. They didn't say what motor it was. The mechanic said he sees more and more motors like that and he blamed it on poor engine designs and excessive heat. A representative for the automotive industry blamed it on vehicle owners lack of maintenence. Another mechanic said owners should follow the more severe service maintenence guide and use the recommended oils but in certain motors there could still be a problem. CBS stated that SAAB, VW and Toyota had offered extended warranties on vehicles with problem motors. A woman who was interviewed showed a receipt for $3800 for engine repairs to her minivan that she said she had babied since new. She had probably gone to CBS after she had to foot the bill. It ended by saying that various agencies that had received complaints about sludge motors were going to the NHTSB to recall a Chrysler motor that was the source of many complaints. Chrysler's response was that sludge was not a big problem. I'm glad I don't have a sludge motor. Forgot to add that the mechanic said to keep all maintenence receipts as they would be needed if a problem should arise.
