Mitsubishi 4G63 Camshaft Sprocket O-Ring
The above diagram is showing the Mitsubishi 4G63 and 4G64 Camshaft & Valve area, the area we wish to show is at the Camshaft Sprocket near Timing Belt area, under the zone 03171P, let's dismantle the camshaft sprocket for a better view.
This is the camshaft sprocket looks like, sometime mechanic will found oil leaking at this area, and is it necessary to change the whole sprocket to solve the problem? Now, just look at the sprocket, you may notice there is a grove area in the sprocket, and actually it is seal with an o-ring, possible just a change of the o-ring may solve the leakage problem.
