    Just wondering if anyone has experienced a sort of 'thumping' noise at idle after engine is warm. I noticed it being somewhat pronounced at 62K. My son described it as a thumping vs ticking( not ticking) or clicking more of a whamp, whamp.. Anyone? ( Oh I change my fully synthetic high mileage oil at every 5k like clock work and use ONLY Ford factory filters.

    Does it change with RPM?
    Is it more pronounced inside/outside vehicle?
    Can you pinpoint area under hood?

    Odrapnew, Yes it picks up with engine RPM and disappears or is over powered if you will by regular engine sound. It is harder to hear outside the car but is in the engine compartment but seems a bit stronger on the passenger bckside of motor.

    Random guess but could it be something to do with the timing chain or water pump or something with that part of the engine?

    I am hearing something too on our 13 sport. It is very audible if the engine is warm or after a long drive. It is very pronounced when you come a stop while driving and changes with engine speed. The sound comes from the passenger side of the engine and It also drowns out by engine noise as you drive faster. It's like listen to your own heartbeats, if you don't pay attention, you won't hear it, but once you noticed it, you can't stop. The sound persist even after and oil change at the dealer.

    Mine has been making a wump, wump, rattle, tap, tap noise at lower engine speeds sometimes followed by a cla-chunk that sounds like it's coming from the trans just as the vehicle stops. It also makes a pfft pfft pffffffft noise under heavy acceleration.

    I have a 2014 explorer with 83000 miles on it and it has the same symptoms as yours. I scheduled an appointment at my dealer but can't get in for over a week. I'd love to hear if anyone has found out what the problem is and I will be happy to post my findings as well.

    Mine is going in on Thursday this week for the tech to get underneath it etc. So we will see what is up. Ill see if I can record it when it is running so it is noticable.

    I brought mine into the dealer this morning and they just called and informed my that my timing chain is stretched and a guide for it is broken. They recommended a new chain, guide, and water pump for a total of about $3000. I still hope to hear from anyone else to see if they got the same diagnosis.
