Mitsubishi’s 1.3-liter 16-valve 4G19 engine was assembled in Japan from 2002 to 2012 and installed on the sixth generation of the popular Colt model and only in some markets. It is important not to confuse this engine with the 1.3-liter 4A90, which was installed on the Colt at the same time.
On the sixth generation of Colt, a new 1.3-liter unit of the Orion family appeared, which was distinguished from its predecessor by the presence of a MIVEC-type phase regulator on the intake shaft. Otherwise, this is a common engine for this series with multiport fuel injection, a cast-iron block, an aluminum SOHC head with one 16-valve camshaft and hydraulic lifters, an ignition system with individual coils, an EGR valve and a timing belt drive.
4G1 (Orion) family: 4G12, 4G13, 4G15, 4G15T, 4G18, 4G19.

Disadvantages of the Mitsubishi 4G19 engine
- The oil burn of this unit begins much later than that of its counterparts in the series, but by 150,000 km thin oil scraper rings lie down and consumption still appears. Sometimes you can do with a simple decarbonization, but usually only the replacement of rings helps.
- The problem with floating revolutions, proprietary for the Orion series, due to throttle wear, is also not as pronounced here as with older power units of this family. But restored dampers for such a motor are sold, which means someone needs them.
- A common cause of failure of this engine is a broken timing belt. According to the regulations, it serves 90,000 km, but it can burst earlier and with a bend in the valves.
- Also, the owners complain that when starting in severe frost, they often flood candles, the ignition coils, the cooling system fan and the rear engine mount do not run for long. The short-lived catalyst and the EGR valve that is quickly overgrown with dirt are also often scolded.
