Hi guys, I have a 2021 Triton. The rear welsh plug on the head has started leaking, and mitsubishi want to charge me $9,000 to replace it. They told me it has started leaking due to my bullbar on the front causing the engine to run hotter than it should and it has caused the welsh plug to leak as the relief point.
Is there any point to fighting this, or should I pay the $9,000 and sell the car? This last issue has been the nail in the coffin.
