Ok guys, I have my motor out and while its out I wanted to look at my exhaust manifolds to be sure they dont have the cracking most get but cant see anything.

Does anyone have a picture of where they normally crack?

Thanks
 
The exhaust manifolds crack at the collectors, on the inside of the Ys. If you have cracks, they'll be readily apparent.
 
At the welds.
 
Thanks guys, I dont see any cracks so assuming im good as well as it was not loud before I pulled the motor.
Just wanted to double check and maybe re-weld is I had signs of them starting .
 
2000-01 4.0L have cast iron exhaust manifolds that do not crack. 1999 and older manifolds commonly crack as pictured.

Good to know as I was looking at both exhaust manifolds and did not see cracks on either one (2000, and 2001).
