America has a posh relationship with diesel engines. Diesels are the life-blood of the transport sector, offering energy for all types of vans and business automobiles throughout the nation. However generally, American carmakers make diesels that develop horrendous reputations.
Eric from the I Do Automobiles YouTube channel finds out why Jeep’s EcoDiesel engine has such a foul repute in his newest teardown video. Initially discovered within the last-gen Jeep Grand Cherokee and variations of the Ram 1500, they’re well-known for failing prematurely, with tough-to-find elements and plenty of extraordinarily tight packaging.
The one cause we all know this engine is dangerous is as a result of it could not be spun by hand, indicating one thing’s gone flawed with the rods or crankshaft. From the skin, it seems pretty wholesome, with no seen indicators of injury. You would not comprehend it was damaged judging by the heads. The areas below the valve covers are like-new, with none staining and minimal scoring.
It is solely when Eric removes the heads does the injury develop into clear. One of many pistons, in some unspecified time in the future, smacked into the valves, making a transparent imprint on its face. Positive sufficient, when the oil pan is eliminated we will see copious steel shavings that, in accordance with Eric, was bearings for the connecting rods.
The bearings disintegrated, inflicting one of many rod caps to detach from the rod, liberating the crankshaft to chuck the piston into the top. The rod cap bounced round within the crankcase earlier than wedging itself between the crankshaft and the block, seizing the motor. Yikes.
Eric suspects a scarcity of upkeep and a scarcity of floor space for the bearings are what led to the failure. Seeing as how he is takes engines like these aside for a residing, we suspect he is onto one thing. Eric has taken aside quite a few EcoDiesels, and says they’ve all had related issues with the underside finish.
Our suggestion? Simply go for the gasoline engine as a substitute.
