From 1982 to 1992, a Japanese plant assembled the 1.8-liter Toyota 1C diesel engine, which was used in numerous small cars at the time, including the Carina, Crown, and Corolla. It was common to refer to the catalyzed versions as 1C-LC and the transverse versions as 1C-L.
From 1982 to 1985, the company produced the Toyota 1C-T turbo diesel engine, which was limited to the European Camry model and its Japanese equivalent, the Vista V10. The unit was referred to as 1C-TL or 1C-TLC in the catalyst-equipped version because it was positioned transversely.

Disadvantages of the Toyota 1C engine
The most well-known issue with these diesels is overheating-related cylinder head cracks;
Additionally, the motors in this line frequently have damaged valve seats;
Here, air pipelines frequently break, allowing dust to enter the cylinders;
Because of the cylinder-piston group’s wear, compression decreases after 200,000 kilometers. Keep an eye on the timing belt because if it breaks, the camshaft will burst and the valves will bend.
