Engine Toyota 2ZZ-GE under the hood

Engine Toyota 2ZZ-GE

The Toyota 2ZZ-GE engine has a fairly large potential – about 500,000 kilometers. But its real life depends to a large extent on the quality of oil and gasoline. The motor is too sensitive to inferior materials. The high engine speed threshold has proven to be an advantage for many drivers. But this also made the unit not too high-torque at low revs – you have to turn the engine hard to achieve good dynamics. And this despite the fact that the unit uses the Turbo system.

Frequent problems

  1. Oil burn. The most common problem with 2ZZ when passing the mark of 150 thousand kilometers. Decarbonization helps temporarily. As a result, a major overhaul or replacement of the motor cannot be avoided.
  2. Noises and knocks inside the motor. The main reason is a loose timing chain. Replacement required.
  3. Instability of revolutions. It is necessary to clean the valves at idle speed. Also, the reason may be in the throttle-valve module – diagnostics required.

The periodic whims of the VVTL-i-system are added to the list of problems. For prophylaxis, after 50 thousand km of track, it is necessary to replace the lift bolts. If this is not done, the system may fail and, as a result, the power will drop over 6 thousand rpm. The durability of the motor does not exceed the same indicator 1ZZ, that is, no more than 200 thousand km. Alternatively, it can be replaced with 3S-GTE.

The main structural problem of the 2ZZ GE motor remains the ultra-small jumper between the cylinders:

  • during the cooling of the aluminum cast block, the formation of shells, cavities is possible with a probability of more than 75%;
  • aluminosilicate inclusions have a different cooling rate, microcracks form near them;
  • during the curing process, a porous structure is possible, again due to foreign inclusions of aluminosilicate.

Such an internal combustion engine device is initially prone to liner scuffing. The mesh of the hone (special coating of the inner wall of the sleeve) is wrinkled, unlike a similar coating of a steel or aluminum sleeve. The manufacturer declared the resource of the sleeves to be sufficient, but did not ensure this in practice.

All of the above is true for the piston, since this part is manufactured using a similar technology. The hardness of the piston skirt is increased by applying phosphorus-containing and iron-containing coatings.

Through long tests, the manufacturer managed to achieve wear of the piston rings, and not the liners in this friction pair, to slightly increase the maintainability of the cylinder-piston group.
