How to distinguish intake and exhaust valve seals on Mitsubishi Pajero?
2 Answers
Mitsubishi Pajero valve seals can be distinguished by color: blue indicates intake, while brown indicates exhaust. The function of valves is to specifically input air into the engine and expel exhaust gases after combustion. Structurally, engine valves are divided into intake valves and exhaust valves. The active safety system of the Mitsubishi Pajero helps drivers avoid traffic accidents, such as the four-wheel ABS system combined with an electronic brake-force distribution system. Passive safety features include dual airbag systems for both the driver and front passenger, an energy-absorbing steering column, and side impact bars, which reduce the risk of injury to occupants in the event of an accident.
I remember that when distinguishing between intake and exhaust valve seals during Mitsubishi Pajero engine repairs, the key is to look at their position and features. The valve seals themselves look similar, but the intake valve is on the intake manifold side, while the exhaust valve is on the exhaust manifold side—just identify their positions during disassembly. The exhaust valve seal is designed to be more heat-resistant and may be slightly larger or marked with a darker color. Before installation, measure the inner diameter with a ruler: the exhaust seal is slightly wider. If you don't have a manual, observe the engine layout—the left side is usually intake, and the right side is exhaust. Don’t install them backward, or it could lead to oil leaks and engine damage. Regular maintenance can reduce this issue, especially for older Pajeros. I recommend buying an OEM kit, which comes with distinguishing marks, saving time and effort.
