Owning any automobile comes with unknowns. Issues will come up, issues will break, and exhausting selections have to be made. Many main issues in trendy crop up effectively previous the 100,000-mile mark, however one 2018 Nissan Titan XD proprietor is going through a giant restore with simply over 40,000 miles on the odometer. It’s dangerous sufficient that the truck may require a brand new engine block.

This junk 5.0-liter V8 Cummins diesel engine engine reveals itself throughout a dissection at Dave’s Auto Center in Utah, which printed a video documenting the motor’s disassembly to YouTube. A brief run reveals it’s leaking a copious quantity of oil out of the again with a doubtlessly blown rear principal seal.

According to the proprietor, the Titan’s engine grew louder earlier than dying on the aspect of the street, however there weren’t another indicators of misery beforehand. It did not show a verify engine mild, oil strain mild, or a excessive engine temperature.

Despite that, one thing went terribly flawed. Particles within the oil filter, oil, and oil pan level to a catastrophic failure, and additional tearing down the engine reveals a number of spun principal bearings and in depth harm all through. The crank journals are scuffed, and the engine will want new caps.

Spun bearings are one of many worst sorts of failures, able to killing an engine in seconds. They do not simply occur out of nowhere. The phenomena often happens because of a drop in oil strain, inflicting metal-on-metal contact between the bearings and journals, growing friction and warmth that results in harm and engine failure.

Sadly, it seems to be just like the Titan’s engine block is junk. Fixing it’s potential, however a brand new block is probably going the higher place to begin. Neither might be low cost, with a brand new block from Nissan costing $23,000. That doesn’t embrace the value of labor to place it again within the pickup, both.
