Up Pipes
I've a 99 7.3PSD. I was told I had an exhaust leak. It can be heard inside the cab on passenger side. I looked at the exhaust manifolds and do not see any signs of leakage there. I have heard of these up pipes and that the donuts need to be changed to stop exhaust leaks? What are the up pipes, where are they located and how does on take them off? Is there a thread here at FTE?
Thanks
Thanks

on the passenger side..in front of the front tire..just above the frame rail on the manifold you will see a steel line (looks like a brake line) it go's up to a sensor at the front of the motor..this is a back pressure sensor..check that steel tube close..they are noted to split and leak..I am sure that is your problem..

I took this picture of the up-pipes on an E450 that I installed the bellowed pipes on.
See the blackend area right below the Y-pipe? That is where they all leak.
Sorry no pictures of the bellowed pipes, but if you are needing to do this job it's very well worth the extra expense of the bellowed pipes. Once those are installed you'll never have to do that job again.

After I replaced the glow plugs. I checked the up pipes and sure enough the right side shows signs of leakage. I am unable to remove the transmission. Don't have the space or trans jack. Once the turbo/pedestal is removed is the right side pretty easy to change out? Since the right side is leaking would that be why the cab smells of burnt diesel when I let the engine warm up in the winter time? Thanks for all your replies. You guys rock!

I did mine with the turbo out, pedestal out, and the downpipe out. It was a rather simple task aside from the short throw on the 10mm wrench to tighten up the four bolts at the top. With the bellows you loosely hang the pipes ontop of the manifold and then you tighten up the bolts at the collector and then the turbo, then tighten the bolts at the manifold :0
