Chrysler / Dodge 2.7L Engine Problems
From 1998-2000 2.7L Engines are prone to premature catastrophic engine failure due to a defectively designed Timing Chain Tensioner that Chrysler quietly redesigned. Unfortunately, many consumers have had to pay out of their own pockets for this while Chrysler avoids responsibility.
From 1998-2004 Dodge / Chrysler 2.7L Engines are prone to Oil Sludge often caused by internal coolant leakage that has to do with the design of the Water Pump that allows coolant to enter the Engine over time and cause oil sludge, experts at a well known remanufacturing company say. The second common cause of engine sludge is from poor oil circulation caused by oil passages that are too narrow causing the oil to wear down more rapidly unlike normal engines. Another contributing oil sludge factor is possibly due to an inadequately designed PCV system that can also accelerate engine oil breakdown, which Chrysler later made improvements to for the 2005 model year along with other changes knowledgeable sources state. Although Chrysler is aware and there is nothing consumers could have done to cause this, Chrysler still regularly blames consumers for 2.7L Engine Oil Sludge.
