Oil sludge buildup and sludge-related engine failure is a design DEFECT in Chrysler's 2.7L engine
Since 2001, one of the most commonly reported problem on CarComplaints.com has been engine failure or timing chain problems with Dodge’s 2.7L engine, all caused by oil sludge.
What is Oil Sludge?
Think of it like a heart attack for your engine: thick, oily sludge clogs oil passageways in the cylinder block. The clogging of these passages leads to oil starvation for moving parts such as valves, pistons and camshafts.
This can cause parts to seize and lead to engine-destroying failures. Read more about the messy problem on OilSludge.com.
The Problem with the 2.7L DaimlerChyrlser Engine
In theory, preventing oil sludge should be as easy as regular oil changes. However, certain engines are predisposed to this sticky situation.
DaimlerChrysler’s 2.7L V6 engine has a leaky, poorly designed water pump. When coolant from the pump mixes with oil it speeds up the sludge process. The engine can be found in many early-2000 Dodge vehicles, including:
- Dakota trucks, both gen 1 and gen 2 (1999-2003)
- Durango SUVs, late gen 1 (1999-2004)
- Intrepid cars, gen 2 (1998-2004)
- Stratus cars, early gen 2 (2000-2004)
We put the Intrepid in bold because from 1999-2001 you were pretty much guaranteed to get sludge.
