The April 18th issue of Automotive News has a lengthly article about sludge engines. Unfortunately I don't have any way to post it. There is a chart that shows the engines of most concern. Chrysler 2.7 from 98 to 02 has 1,000,000 high risk engines. Saab 2.0 and 2.3 from 98 to 03 has 135,000 high risk engines. Toyota 2.2 and 3.0 has 3,300,000 high risk engines. VW 1.8 from 97 to 04 has 426,000 high risk engines. Clarence Ditlow, executive director of the Center for Auto Safety is pushing to get the automakers to have recalls. He was quoted as saying "Oil sludge is our No. 1 priority this year." Some automakers have been more helpful than others. Toyota now has an extended warranty for this problem but they generated a lot of bad will before doing it. Saab has also extended the warranty on the engines they say are at risk. Chrysler still is generating bad will and so far has taken a pretty hard line. Evidently the internet is ablaze with tales of refused claims. I have a feeling that we will be hearing even more about this very soon.
