      Sealing back of the car didn't make any difference for me after the dealer done the TSB.

      Even i did extra sealing by my self on the back. nothing has changed until i started to seal the hood rubber and covered my fresh air intake.

      at that time i realized this is it, this creepy issue is not from the back.

      Understood, but your original comment was that my post had 'confirmed' your theory, when in reality it worked against it.

      (I'm not knocking out your evidence as much as clarifying my experience, however.)

      i still didn't confirm the cracked manifold, but i think it's the reason what causing the engine bay to be filled by exhaust.

      what i can confirm 100% sure is sealing the rubber is worked for me.

      Correct me if i was wrong, but you mentioned in your previous comment that you had a cracked manifold and after you fixed it the problem was gone ? based on this i said your comment confirmed my theory.

      No, I said that it was checked, but that it was 100%--as it was--it wasn't replaced.

      No worries--I was more worried about my clarity than anything else. As I said, I didn't want to take away from your evidence nor conclusions--simply that I wasn't a helpful tale to that end.

      I'm not really sure this is anything new. Any smell/odor/gas has a pathway into the vehicle through the fresh air vent. Any exhaust leak that allows gases to accumulate in the engine compartment/front of vehicle may find its way to the fresh air vent and inside the vehicle as the hood is not exactly sealed all the way around.

      It doesn't necessarily have to be from a cracked manifold either. It could be due to a poor seal between 2 mating surfaces or a leak at a gasket.

      Or perhaps no one else is having that exact same issue.

      Its the exact same issue that a lot of Explorers have it “exhaust smell inside cabin during hard acceleration “

      I meant exhaust coming in from the front, not the back. Many that have had the back sealed no longer have the issue.

      My local Dealer did the TSB and the issue didn’t solved, The dealer sealed so many places in the back. after one week I started notice the smell again. And also I’m following the main thread for this issue, many members has done the TSB and the issue didn’t get solved.

      True, but many also did. I've had the hood open while the engine was running and never smelled any exhaust but then I've also never had the 'exhaust' issue on my Explorers. I would think that if one was smelling exhaust in the engine compartment then there is something wrong there. Exhaust should only exit via the tail pipes.

      I just got a another confirmation from Manuel Garcia

      He tried it on another Explorer 2016 and it worked !

      So until now confirmed worked for:

      my Explorer 2015

      Manuel Explorer 2014

      and another 2016 explorer

      You guys need to take my thoughts more seriously, i'm actually disappointed that i got some doubts in this thread.

      I'd try this, but I don't have any smell regardless of how I drive or HVAC settings.
      If I had the exhaust smell issue, I'd definitely try this before bringing to the dealer, but fortunately, I don't get the smell.

      Also, Manuel essentially sealed his inlet to the vehicle with tape. If you fully seal the inlet, it's possible that there is little air exchange going on in the cabin(no air in -> no air out). So, he might not be sealing the exhaust entrance, but he might be preventing the exhaust from entering somewhere else(if that makes sense).

      Now, assuming this sealing proves to be a solution, the question still remains, how is the exhaust getting to the inlet? There has to be an exhaust leak somewhere if the exhaust is entering through the inlet at the base of the windshield. It would lead to more likely that it's a crack or joint leak.

      I believe your theory and results, I just don't believe that the defect you've discovered is the only/exclusive one that leads to the problem at hand.

      I have brand new 2017 XLT with 3.5. Less than 1000 miles. I definitely notice the smell. But notice it more OUTSIDE vehicle! I remote start it and then when walking out to it I notice smell as approach from front walking to driver door. Also noticed it when stopped at redlight. I had read this so instead of taping, I just put HVAC on recirculation. Haven't noticed smell when on recirculation. The smell doesn't smell like typical exhaust to me. Smells more like something burning-like when you burn hair. Regardless, there has to be a leak in exhaust system. You should not have exhaust smell around vehicle like that-if it is coming from exhaust. Too cold but I would like to put it up on ramps and looks at it from underneath. Can you see manifolds from below? Would like to look for and leaks. put some kind of CO sniffer there and see if get reading. But the kind of tester I want is too expensive. Even if the Ford seal fix works, doesn't seem like true fix, just masking the problem of a leak. If accelerating, all the exhaust (coming out tailpipes) would be behind you. How is that going to enter cabin unless you have a leak somewhere!

      This is what i'm assuming, there is a exhaust leak from the exhaust system and it could be a cracked manifold same that have been reported in PIUs, but someone told be this cracked manifolds only for the 3.7s not 3.5. but i don't think so.

      so it could be crack in manifold or gasket. i didn't get a time to check the manifolds, i use seafoam to smoke the exhaust and check if there is any leak.

      well it's combination of two problems, i still didn't confirm where the leak comes from.

      my idea to discover the leak is using seafoam to smoke the exhaust and check underneath the vehicle.

      Why don't you give it a try and cover you fresh air intake with duct tape and accelerate ? btw you point : But notice it more OUTSIDE vehicle! I remote start it and then when walking out to it I notice smell as approach from front walking to driver door

      this what makes me believe the exhaust issue is not from the back of the car. i can smell it when i approach the front tiers.

      i have an idea to find the leak i will do it soon, using seafoam to smoke the exhaust.

      Black Eyed: keep up the good work on helping to troubleshoot this problem. The exhaust manifolds on my Explorer has a shield covering the front manifold from the top side. I tried to use my inspection camera to look between the shield/cover and the manifold but could not get the camera to focus well enough. I have been holding off on more testing; as my Explorer does not fail as much in the cold weather. Have had the high 30-40 mph wind plus wind chill in the -20s degree F range lately.

      Thank you for your appreciation, I don't think using inspection camera would help, cracks need to be seen with bare eyes, i think using seafoam to smoke the exhaust will get a result, plus cleans the engine.

      A good inspection camera would show a crack you could see with the naked eye. I’d think if you had an exhaust leak large enough to saturate the engine compartment with smell you’d hear it leaking.

      I think you are also taking it too hard that everyone isn’t jumping with praise over your theory. I do not buy this theory that this is where he exhaust smell is coming from in all of the Explorers, or even the vast majority of them.
