Exhaust Manifold leaking (pics).
I had posted in another thread about my exhaust manifolds leaking where they meet the head. I'll pick up gaskets tomorrow from the dealer.
For the past month my EGT's have been higher that normal, and my boost has been lower than normal. These symptoms can also be caused by damaged CAC system, and/or the up-pipe and y-pipe flex/expantion joints. In my case, it was the exhaust manifolds.
You can visually see the soot marks on the head and exhaust manifold.
In the first pic, you can see where I marked with a yellow paint pen, the exhaust manifold flange. Notice how clean the flange and head are where they meet. In the second pic, notice how soot is leaving the flange and head showing a leak. You'll also be able to take your finger and rub the soot. A good sealing manifold to head will not have soot blowing out.
