How big is the intake valve on a Mitsubishi 4G63?
The intake valve diameter is 33 mm; the exhaust valve diameter is 29 mm. The all 4G63 engines were equipped with Mitsubishi’s electronically controlled multi-point fuel injection system named as ECI-MULTI. The DOHC engines also got the electronic ignition.
Are there any problems with the Mitsubishi 4G6?
But the 4G6 is still being installed by some Chinese automakers in new vehicles today. The hydraulic valve lifters are very sensitive to the fuel quality. Not replaced engine oil in time can easily reduce their longevity down to 30-40k miles. The jammed bearings of balance shafts can lead to serious engine damages.
