The last two times I've driven the car, as soon as I shut it off, it starts making a sizzling and poping noise from under the engine. I noticed there was no distinct burning smell of any sort so I figured it must be a water issue and even though I've driven it a bunch with the A/C on this year without any of these issues, I started thinking it might be the A/C drain line dripping onto the headers. So I jacked the car up and sure enough, the header wrap actually split as I was sliding under the car from one of the pops. It was soaked and had no odor from the liquid. So I'm assuming the A/C is draining onto the headers and running in between the header wrap and headers..?? It looks pretty tight up in there and this is a new problem and nothing has been changed that would create this condition, so I'm curious why this started now. Wondered if any of you have experienced same thing and what caused/fixed it. Figured I would ask before I start taking stuff apart. Thanks guys.
