Parts for your 2006 Mitsubishi Pajero-Oil cap

2006 Mitsubishi Pajero oil cap — what it does and how to look after it

Technical references confirm the 2006 Mitsubishi Pajero is fitted with an engine oil filler cap and absolutely relies on it. The Mitsubishi Motors 2006 Pajero Owner’s Manual identifies the engine oil filler cap on the cam/rocker cover, and the factory Workshop/Service Manual for the V80/V90 series (covering the 3.8L 6G75 petrol and 3.2L 4M41 turbo‑diesel) shows the cap and its sealing gasket as part of the cylinder head cover assembly. Independent repair guides such as Gregory’s and Haynes also depict and reference this cap. So yes, an oil cap is relevant and used on every 2006 Pajero.

On this model, the oil cap does more than just give you a place to pour oil. It seals the top of the engine so dust and moisture can’t sneak in, keeps engine oil from splashing out under the bonnet, and helps maintain the crankcase ventilation system’s pressures. A missing, cracked, or loose cap can lead to oil misting around the cover, a messy engine bay, odd idle behaviour, even a check engine light on some variants.

As part of regular servicing, it pays to give the oil cap a quick once‑over. Pop it off and check the rubber seal for flattening or hardening, make sure the threads aren’t chewed, and confirm it tightens smoothly by hand. Wipe the seating area clean before refitting. If the seal is perished or the cap’s distorted, replace it—genuine or quality aftermarket is fine, but match it to the engine variant. No need for tools or big torque here
