America has a posh relationship with diesel engines. Diesels are the life-blood of the transport sector, offering energy for all types of vehicles and business automobiles throughout the nation. But generally, American carmakers make diesels that develop horrendous reputations.
Eric from the I Do Cars YouTube channel finds out why Jeep’s EcoDiesel engine has such a foul status in his newest teardown video. Originally 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 components and many extraordinarily tight packaging.
The solely purpose we all know this engine is dangerous is as a result of it could not be spun by hand, indicating one thing’s gone fallacious with the rods or crankshaft. From the skin, it seems to be pretty wholesome, with no seen indicators of harm. You would not understand it was damaged judging by the heads. The areas below the valve covers are like-new, with none staining and minimal scoring.
It’s solely when Eric removes the heads does the harm turn into clear. One of the pistons, sooner or later, smacked into the valves, making a transparent imprint on its face. Sure sufficient, when the oil pan is eliminated we are able to see copious metallic shavings that, in response to Eric, was once 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 comparable issues with the underside finish.
Our suggestion? Just go for the gasoline engine as an alternative.
