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.

I got a dumb question. How does this increase your egt's?

When you install the gaskets, if you can take note of how you're getting to the bolts and describe the process that would be great. Mine are leaking as well, and I have a broken one on the passenger side. I want to fix the thing, but am really worried about opening a can of worms. Obviously removing the broken bolt will be the most difficult part for me.

The way I'm thinking is, lack of boost (clean forced air) don't match the amount of fuel being dumped into the cylinders. Less boost with the same amount of fuel raises EGT. Then again I've been wrong before! LOL!

Same concept at having a cracked flex joint.

I'll take notes and pics when I go to install. If the dealer has them in stock on monday, I'm gonna try to find time on Tuesday. I plan on taking out the inner fender wheel well, only gonna do the pass side, driver side is still sealed good.

That would be great! I had the inner fender removed once, it's not too hard to do. Getting it back in just requires some patience. On mine both sides are leaking, but the drivers side seems a little easier to get to (and I have no broken bolts on that side)

Thanks, bud, makes sense. I was trying to grasp the concept.
