Mitsubishi 4G69 2.4L engine reliability, problems and repairs
The updated version of 4G64 called 4G69 was released in 2003 on Mitsubishi Grandis and Mitsubishi Outlander cars and became the last representative of the Sirius engine family (which, in addition to our engine, included: 4G63T, 4G61, 4G62, 4G63, 4G64, 4G67, 4G69, 4D65 and 4D68). The new engine has reduced cylinder block height to 229 mm compared to its predecessor, increased cylinder bore to 87 mm (from 86.5 mm), lightweight pistons (278 g vs. 354 g in the 4G64), lightweight crankshaft (14.9 kg vs. 15.8 kg in the 4G64) and connecting rods (530 g vs. 623 g). The cylinder head is new, with MIVEC timing system on the intake shaft and valve lift height, increased diameter of intake valves to 34 mm, exhaust valves to 30.5 mm. There are no hydrocompensators on the 4G69, so every 40-50 thousand kilometers it is necessary to adjust the valves, the intake valve gap on hot 0.2 mm, the exhaust valve gap 0.3 mm.
In addition, a version with direct fuel injection GDI was released, the compression ratio on such motors is increased to 11.5. The intake manifold was completely redesigned, and the exhaust manifold was changed along with it.
The timing drive is belt drive, the belt width has been reduced, the resource has remained the same, about 90 thousand kilometers. Together with the belt, the balancer shaft belt was also replaced.
Currently, the 4G69 engine is produced under license for automobile companies from China, Mitsubishi itself instead of it installs a more modern version 4B12.
Diseases and faults of Mitsubishi 4G69 engines with a volume of 2.4 liters
On diseases and faults 4G69 resembles 4G63, but problems with vibration are now observed much less often, on the other hand more modern motor likes quality gasoline and saving on it, at least, will lead to the rapid replacement of the catalytic converter. Otherwise, the engine is excellent, careful attitude, quality oil, gasoline and regular maintenance will provide maximum trouble-free operation, the resource of 4G69 in this mode can exceed 400 thousand kilometers.
Mitsubishi 4G69 engine tuning
Turbo. 4G69T
The only more or less reasonable option for tuning a standard 2.4-liter engine, is to buy and install a cylinder head with all the associated from the Lancer Evolution. What’s more, there are entire bolt-on kits available for the turbocharged 4G69.
