Disadvantages of the Toyota 4Y-E engine
This power unit has a high risk of overheating, usually due to a gasket failure;
Additionally, the jumper between the antifreeze channel and the fourth cylinder could collapse;
It is essential to broach the cylinder head after 1500 kilometers following gasket replacement;
Oil consumption is a common issue for many owners, especially during the first kilometers of operation; lubrication leaks or ignition system fluctuations are the main causes of the remaining issues.
