up pipe leak??

[dandevries]

i was under my truck the other day and noticed a little soot around the up pipes where they come off the manifolds, on ferther inspection it looks like the bolts are rusting through. i was wondering if they are jus bolts or studs off the manifolds?? if their studs any tips on getting them out? thanks its a 97 7.3 btw

Should be bolts. Soak them the night before with a good penetrating lube. They are dimpled and likely rusted so they will be stubborn.

ok thanks is their a gasket i need to replace or is it just a pressure fitting

Gasket but Ford suggest to also replace the up-pipes because the gasket wears a grove in the up-pipe. I just had a buddy help me build a set like diesel site sells for 500 bucks. Its got a flange on the turbo end with an expansion joint.

Just had a dealer replace mine. It would have been an absolute nightmare to do it myself. Ford Diesel Tech took 4 days to do it and he had all the right equipment and know how. Was just intending on replacing the gaskets with Beans Diesel brass gaskets but my up-pipes were extremely worn and all the bolts and studs busted off on him. $1200 job around Christmas really sucked, but boy did it make it run better. Cooler EGT's, better Econo, faster spool up, and its much quieter up front, of course I don't notice it as much now since I've gotten used to the improvements. Good luck!!
