Hey, I haven't heard of this, but where was it cracked, how many miles on your truck, etc?

From what I've read about header installs, replacing the exhaust manifolds is a lot of work. Only car I ever broke an exhaust manifold on had a bad motor mount that let the motor move and hit either the frame or fenderwell. Probably not the case in your truck, but maybe worth checking out.

There have been a few Titans with cracked manifolds. Some owners that had the infamous "engine tick" were not able to fix the noise with a ground wire like most of us did. It ended up being a cracked manifold. Don't know if Nissan redesigned these or not.

I went through a set of manifolds on my '00 Tundra after only 15,000 miles. I put headers on before they cracked again.

Hi,

Can you share as many of the symptoms as possible. This way we can all be aware and listening.
Thanks

Already had one replaced on mine. It sounds like I need another one because I have a terrible exhaust leak again.

You'll usually hear a ticking sound that is usually louder when the motor is cold. Sometimes the ecu will throw out "lean" codes for the primary O2 sensor for the bank that's leaking.

Thats the Xterra blood in them. Almost all early xterras had their exhaust manfold crack. They also had the fuel spit back out the filler hole.

I think my manifold maybe cracked as well. When you give it gas while in park you can hear a rattle at the peak rpm. My engine runs rough and will vibrate the whole truck after you let go of the gas. Also I can hear my truck whistle, even while idleing if I put my ear up to the grill. Also, the service engine light will flash for about a second when you give it gas! Anyone know the exact symtoms of a cracked one? ???????????????????????????????

Took it to the dealer and they said it's just the fuel injectors? I'm taking it to a muffler shop to get looked at, Free.

The older Frontiers had this problem as well. Nissan redesigned the new manifolds with more material where the cracks were happening.
