Hello friends, this is my first thread post for my first tundra (had various cars and trucks in the past).
This past summer I bought a 2007 5.7L Dbl Cab 4x4 SR5 off eBay. 165k miles, but seems to be very well maintained.
I really do love this truck.
I haven't had any issues and the truck has been running great, except the annoying exhaust manifold leak/diesel truck-sound. It is most prevalent when driving next to a wall or fence (on either side), but I can still hear it when I just drive around town with the radio off, especially when you give it a good amount of gas.
I inspected as much of the exhaust and exhaust manifold as I could but couldn't find any leak or carbon build up/deposit. There is no rust or indication of a bad gasket or cracked manifold. I've tried to do as much research as I could online and have found that there is typically a weak spot in the factory manifolds on the driver side where the weld for the air injection tube enters the exhaust manifold breaks or tube #3 leaks. Not sure if these are the same tubes/weak spots, but I think they're at the back of the engine and hard to be seem.
I would love any advice on how to proceed. I am not even sure if this is where the leak of my exhaust is, but it definitely sounds like a manifold leak (flapping/diesel sound), there is no leak or crack or rust to be seen and it seems that this is a common problem for our trucks. I would love to fix this soon and cheaply as possibly, so I can proceed ahead with other mods/maintenance with my truck. Not sure if this could be a DIY project, but I would be willing to take a stab at it if it is just bolts and tubs to replace. Anyways thanks everyone for their time and help
