The 1.8-liter Toyota 1C diesel engine was assembled at a Japanese plant from 1982 to 1992 and was installed in many compact models of its time, such as the Carina, Crown and Corolla. The transverse versions were commonly referred to as 1C-L and the catalyzed versions as 1C-LC.
The Toyota 1C-T turbo diesel engine was produced by the company from 1982 to 1985 and was installed only on the European version of the Camry model and its Japanese counterpart Vista V10. Since the unit was placed transversely, it was called 1C-TL or 1C-TLC in the version with a catalyst.

Disadvantages of the Toyota 1C engine
- The most famous problem with these diesels is cylinder head cracks due to overheating;
- Also in the motors of this line, the destruction of valve seats is often found;
- Air pipelines here often crack and dust enters the cylinders;
- Therefore, by 200,000 km, compression drops due to wear of the cylinder-piston group;
- Watch the timing belt, because when it breaks, the valves bend and the camshaft bursts.
