Toyota's 2JZ engine is an extraordinary task of engineering. Offered in a multitude of automobiles in the Nineties and Aughts– consisting of the famous Mk. 4 Supra– it's gotten a credibility of being the most robust internal combustion engine ever constructed. The age-old straight-six can holding substantial power numbers with the ideal mods, and, as this teardown video programs, can choose numerous countless carefree miles with simply standard upkeep.
The I Do Cars YouTube channel got its hands on a running 2JZ engine out of a Lexus GS300 with an unbelievable 415,000 miles on the odometer. Curious to see what this engine may appear like after numerous miles, the channel's host, Eric, chose to take it apart.
Unexpected nobody, the within this 2JZ remains in shockingly good condition, all things thought about. While no motor can be ideal after 400,000 miles, the head and camshafts reveal just small wear and minimal varnish staining. A lot of engines appear like this after simply 100,000 miles, even with excellent upkeep records.
Going much deeper into the engine exposes more of the very same. The cylinders still reveal the majority of their initial cross-hashing, with only small scoring in a number of areas. Not best, however after 400,000 miles, we ‘d state that's a win. And aside from some sludge in the oil pan and regular bearing wear, the bottom end is otherwise healthy.
If you, for some factor, had any doubt about the 2JZ's track record for bulletproof dependability, we hope this teardown encourages you otherwise.
