So ive had this annoying ticking sound which would go faster if i accelerate so i figured it would be a small exhaust leak. Today i went under the car to see whats going on and i discovered that the o2 sensor weld was all rusted up and i saw a small hole in it. Im pretty sure that the water from the ac always drips down that spot and that is what caused it to rust/create exhaust leak. I am going to attach a picture of the whole thing.
Could i just get some exhaust leak putty and seal it off? Thanks in advance.
