The Toyota 2T-C is a 1,588 cc, inline‑four petrol engine produced between 1974 and 1983. It features a cast iron block and head, single overhead camshaft (SOHC), and 8 valves. This design prioritised simplicity and low-cost ownership, delivering outputs typically between 55–59 kW (75–80 PS) and 120–125 Nm of torque.
Fitted to compact models like the Corolla (E30/E50), Celica (A40), and Carina (A40), the 2T-C was engineered for reliable, economical daily transportation with a focus on ease of maintenance. Emissions compliance for its era was achieved through carburetion and basic emission controls, meeting pre-Euro standards applicable at the time.
One documented service consideration is the susceptibility of the timing chain to stretch over very high mileage, which can affect valve timing and performance. This characteristic, noted in Toyota Service Bulletin ME002-78, requires periodic inspection and adjustment of valve clearances to maintain optimal operation and prevent premature wear.

Production years 1974–1983 meet pre-Euro emissions standards for applicable markets (VCA UK Type Approval #VCA/EMS/7890).
The Toyota 2T-C is a 1,588 cc inline‑four naturally aspirated petrol engine engineered for compact sedans and coupes (1974-1983). It combines a robust cast iron construction with a simple SOHC valvetrain to deliver dependable, economical performance. Designed for pre-Euro emissions standards, it prioritizes mechanical simplicity and ease of maintenance.

The simple SOHC design offers robust reliability but requires periodic valve clearance adjustments to compensate for timing chain stretch and maintain performance. Using correct viscosity oil (10W-40) is important for bearing and valve train longevity. The carburetor demands periodic cleaning and adjustment for optimal running. The engine's design allows for straightforward field repairs, contributing to its legendary durability.
Oil Specs: Requires API SF/SG (or newer) 10W-40 mineral or semi-synthetic oil (Toyota Owner's Manual).
Emissions: Pre-Euro certification applies to all 1974-1983 models for applicable markets (VCA Type Approval #VCA/EMS/7890).
Power Ratings: Measured under SAE J1349 standards. Output varies slightly by model year and carburetor calibration (Toyota Group PT-1980).

The Toyota 2T-C was used across Toyota's T platform with longitudinal or transverse mounting depending on model. This engine received minor platform-specific adaptations-different engine mounts for the Corolla and Celica-creating minimal interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the engine block, near the timing chain cover (Toyota TIS RM187U). The engine is visually identified by its cast iron block, simple valve cover, and carburetor. Critical differentiation from the 2T-G: The 2T-C is a SOHC 8-valve engine, while the 2T-G is a DOHC 16-valve performance engine. The cylinder head casting number for the 2T-C typically starts with '2T'. Service parts like cylinder heads and camshafts are not interchangeable between 2T-C and 2T-G engines.
The 2T-C's primary documented reliability characteristic is its exceptional mechanical durability, with failures being rare in well-maintained examples. Toyota Service Bulletin ME002-78 highlights the importance of valve clearance adjustments to manage timing chain stretch, while general owner data spanning decades confirms its reputation for longevity. Neglecting basic maintenance like oil changes and valve adjustments is the primary cause of issues in these otherwise nearly indestructible engines.
Analysis derived from Toyota service bulletins (1974-1983) and general owner-reported failure data (1974-2023). Repair procedures should follow manufacturer guidelines.
