What is this and how do I fix it?

[scrovak]

Hey all. I like working on my own truck, but I'm not always able to easily identify parts, and the world seems to be sorely lacking in the sort of exploded diagrams and user friendly parts manuals I'm used to using on military vehicles. I was going to replace my exhaust manifold (passenger side) the other day when I realized it wasn't cracked. I took a photo of the part that is cracked, so hopefully someone can identify it for me, and get me on the track to repairing/replacing. You are looking at a part that comes off the top side of the passenger side exhaust manifold, as viewed from the front of the vehicle. My truck is a 98 AWD V8 Explorer. Thanks in advance!

My guess is that it's the pipe to the EGR valve. Just a guess. Keith

yeah, i think that's what it is too. you fix it by purchasing a new one.

Confirmed. You can get a Dorman brand replacement with the bellow at RockAuto.com for about thirty bucks. You'll need a good penetrant, such as PB Blaster or Aero Kroil, and a 1 1/16th" wrench for the manifold fitting. Also, while taking that off, check out the two special rubber lines for your DPFE sensor. Those have a tendancy to burn up when they get to be older than a decade. Those aren't standard rubber lines, so don't replace them with anything but the specific DPFE hoses. I tried a standard emissions rubber hose once to replace one and it burnt up and crumbled within an hour of engine operation.

True story. And if you don't notice them, you will be tracking down P0420 codes forever. Yes, O2 sensor codes...

Thank you so much, Obie! If you're ever in my neck of the woods, I'll buy you a beer!

If you guys have Yuengling I'll drive out there right now, haha. No problem man, and thanks for your service.

 

[scrovak]

Oh we've got Yeungling on tap like it's Bud out here! That stuff is my lifeblood! And thank you for your appreciation, but the work I do is as a contractor right now. That changes with my enlistment in the Army Reserve this fall but, until then, I couldn't accept your thanks. Though I'll pass it on to my brother, currently deployed with the Corps.

 

[koda2000]

thank you both for your service.

I replaced that on my 2000. The updated Ford part does not have the flex ripples on it and seems to be built better. I forget how much I paid for it. Replacement was a pain but it's doable.

 

[scrovak]

Todd, what all was involved in replacement? I want to replace it but was a bit shy at ordering the part from Rock Auto at $30 because it didn't look the same, but you've confirmed it is the appropriate part, just without the silly little ripples. Looks like I have another Sunday project! Well, that and mending or replacing my vacuum line.

 

[IAmTodd]

It's just a bolt at the top and one at the bottom plus two hoses. It you start soaking it in Deep Creep you might have an easy time getting it off. It's just difficult since you're dealing with the exhaust and the corrosion that comes along with it.

 

[scrovak]

Awesome, thanks bud! I usually keep CLP on me at all times, because I'm a fan of firearms and own several - do you think that would cut through, or should I grab some DC?

 

[IAmTodd]

I really like deep creep but if your other stuff will penetrate it go for it.

Just a follow-up, I had AZ check my DTCs and two came up, the one I want to focus on for now is P0455 EVAP Large Leak Detected. One of the probable causes is 'Vacuum leak At Engine', could this be caused by my EGR crack?
