We all know the Montero and Montero sports have their strong points, and sometimes their weak points. One of the things you come to live with if you own a Montero or another model is the horrible design of the oil pan. If you have ever changed the oil yourself on a Mitsubishi you will understand. The drainplugs as situated in the corner of oilpan and a very strange angle. To make things worse the way the drain is placed it is up above the oil level when the oil starts lowering as the fluid volume lowers. This eventually leads to the oil seeping out, spattering outside the drain pan, or dripping onto crossmembers or other parts.

This little device can save a lot of hassle!

Here is the installed valve, totally out of harm's way.
