Hey I am no expert with cars but I wanted to know if the exhaust heater is suppossed to be leaking... I had a valve gasket seal leak and there was oil all over my engine which was fixed so the dealer says and I also notice the exhaust heater is leaking. My eyes are always burning and I was wonder if this could be why. Help...I have an arbitration hearing in the morning and I hope someone can reply back fast... Thanks for your help!!
