Analysis Unveils Reasons Behind Numerous Failures of Jeep EcoDiesel V-6s

In recent years, there has been a growing debate over the use of diesel engines in American automobiles. The industry has grappled with the pros and cons of these engines, the most prevalent being their durability in transport and commercial vehicles. However, where some manufacturers have found success, others like Jeep have been maligned for the premature failures of their diesel engines, particularly the EcoDiesel models. In this analysis, the focus will be on the failings of Jeep’s EcoDiesel engine, why it developed an unsavory repute, and the recommendations on alternatives. Drawing insight from ‘I Do Cars’ YouTube channel, an expert voice weighs in on the course of an EcoDiesel’s malfunction, the clues to its early breakdown, and why it might be wiser to opt for a gas engine.

The Deceptive Exterior of the EcoDiesel Engine


Jeep’s EcoDiesel engine, used in the last-gen Jeep Grand Cherokee and some Ram 1500 versions, has gained notoriety for premature failure. This issue is further exacerbated by parts that are difficult to find and tightly packed, exacerbating the repair process. From the exterior, the engine often appears in good condition, with no visible signs of damage. Even beneath the valve covers, the area looks new, showing no discernible signs of dilapidation. The engine’s decay’s revelation happens after the actual dismantling begins.

Uncovering the Damage


The destruction of the EcoDiesel engine only becomes apparent when the heads are removed. At some point, one of the pistons has collided with the valves, leaving an irreversible imprint. The dismantling reveals a shocking number of metal shavings, remnants of what used to be connecting rod bearings.

The Consequences of a Design Flaw


The breakdown of these bearings causes a rod cap to detach from the rod itself, freeing the crankshaft and forcing the piston into the head. The rod cap then ricochets around in the crankcase before finally jamming itself between the crankshaft and the block, thus seizing the engine.

The Pitfalls of Poor Maintenance and Design


The root cause of these failures is speculated to be a combination of inadequate maintenance and a lack of surface area for the bearings. This problem has been observed in numerous EcoDiesel engines that have been taken apart, all demonstrating a similar pattern of issues.

A Plea for Gas Engines


Given the repeated occurrence of such high-risk issues, the advocate suggests opting for a gas engine instead. The acquisition of a gas engine seems a safer bet, preventing the mechanical debacle that has become all too common with EcoDiesel engines. With a gas engine, owners can expect a much lower-risk experience, proving the adage that sometimes, the old ways are the best.
