I've noticed more than normal engine noise from the passenger side firewall area when driving. I also noticed the when I sat in the passenger seat there's quite a bit of heat from the engine bay coming from the floorboard area. From the top/engine bay it's hard to see where this would be coming from. Anyone run into this before and suggestions on what to look for?
Thanks!

 

It's a very common problem the heat is coming from the muffler/cat and the trans/transfer case on that side. You may want to pull up the carpet and check the insulation under it on the floor, if it's bad or gone the heat will be more noticeable but not completely gone.
