This thread is so funny....It just keeps going on an on while Ford continues to do nothing to fix the problem........Happy Holidays Plum
Plum, it's a cluster you-know-what. That said, my car is fixed and for what it's worth here's how:
1) I had TSB 12-12-4 done back in 2012. My car had a horrendous amount of exhaust coming in at full throttle in the summer down here and this TSB reduced it by about 75%. Some say that this TSB did nothing for them but that was not my experience. I also believe that with this TSB Ford tried to address the root cause of the issue: there are vents for the rear AC system just above the rear mufflers. From what have I read on here, there is a new similar TSB that replaced 12-12-4.
2) There are drain/vent holes in the bottom front of the two rear mufflers. I plugged these with Permatex high temperature silicone gasket maker. This, along with the mileage on the car that seems to make the severity of the smell fade, have completely eliminated the exhaust smell for me. I should say that I run with the rear AC disabled, so if that was on I maybe would still have an issue.
3) Seeing the discussion on here about the rear hatch seal, I decided to apply clear silicone plumbers grease to mine for good measure. This stuff is good for preserving your weather stripping anyway. It sealed so good my power hatch motor had trouble opening the hatch. After I wiped off the excess it was good to go. I don't know that this helped because the smell was really gone before I even did this.
