I'm replacing my engine. Got the old one out, and the up pipes are too corroded at the turbo ends to reuse -- they couldn't form a good seal, so I need to replace.

1. Does anyone know the Ford part numbers for the up pipes? I've looked at the ubiquitous Powerstroke part number list floating around, and it says Up Pipe-see Turbo Exhaust Collector below. But it never actually lists the part numbers.

2. Are there any upgrades I should consider? International makes bellowed up pipes which eliminate the donut seals and leaks. These are sold by a number of folks with or without ceramic coating. But they only fit the larger inlet Super Duty turbochargers, not the ones we have.

Thanks for any help you can give. :)

International part # 1843486C92 for 94-97's, reputed to be outrageously expensive ($800). I'll post back if I find someone selling them.

Thanks Billy -- I actually already bought a set of Bean's brass donuts for use with the old pipes, but my tech says I gotta have new pipes. I can't find ANY pipes online though -- standard or bellowed. I will call my International dealer tomorrow and see if they have anything. From what I'm seeing, if I can find them, I should be able to get a set of standard pipes for roughly $150, but the OBS bellowed pipes are nearly $1000 and very hard to find. I guess they did a limited run of the OBS ones and now it's supply and demand. A few lucky souls got them under $100 off eBay, but there aren't any there now. I set up an automatic search, but I need something quick, so it probably won't help.

This is probably a stupid question but... How can you tell if your up pipes are leaking??

Here are the part numbers that I have in my list:

Turbo Exhaust Collector Donut (at top of each manifold-to-turbo up-pipe)
(Ford) F4TZ-6K854-C
(NAPA) f17250 (Chevrolet application, but works for PSD)

Turbo Exhaust Up-Pipes
(Ford) F4TZ-6K854-A (Driver’s side), cross references to IH 1818165C2 but can't verify if it's correct
(Ford) F6TZ-6K854-A (Passenger side), cross references to IH 1824434C1 but can't verify if it's correct
(International, bellowed up-pipe kit for 94-97) 1843486C92

Turbo Up-Pipe Bolts
(International) 1821640C1 (long for manifold end, 4 required), part number was superseded by part number W300013
(International) 1822895C1 (short for turbo collector end, 4 required), try 1844044C1 which will cross to W301160 which was superseded by W301640
(Ford) 40066R1 (Nuts, 4 required), superseded by W300051

Cheers!

If the pipes are not too bad, someone once posted he had a muffler shop swage the uppipe ends so they were snug inside a new exhaust donut. Also cut off about 10-20 thousandths off of the upper uppipe clamps with a belt sander for better compression of the donuts.

I think David Lott may have 5 of his up tubes for the OBS 7.3 next week. They will finished and hopefully fit check ok within a couple of weeks.

That is my latest rumor.

Thanks. I've already purchased new stock up pipes from Ford, and the new engine goes in this weekend (hopefully).

BTW, I got prices from Ford (Wabash Ford -- powerstrokeshop.com) and International on all major parts I needed for this which were available from both. I was very surprised to find that Ford was cheaper in all cases except for a few o-rings. Either Ford has lowered their parts prices, or International has upped theirs.

How well do the brass donuts work? Mine are just starting to show some soot the last 5k or so

The IH place in Denver is very expensive so I never go there. I think you have the same one in the Springs.

Hi TD -- Do you mean that you have the brass rings and they are leaking after only 5K miles? Or that your regular donuts are starting to leak, and you are considering replacing them with the brass ones?

I bought the brass rings for mine, but everything is still apart, so I can't say how well they work. I've heard that they work well, but are difficult to install (heat the rings with a torch and use lots of lube). But I don't think there are that many sets out there yet, so I would say that the reliability is still unknown.

Yes, it's the same company. But I wonder if it's just them, or all International dealers? In other words, are the high prices coming from our dealer or from International?

I 've noticed the same thing over the past several years, I think its a IH price scheduling deal, not the individual dealerships. Years ago they were the place to go, especially if you knew what you wanted.

The place I have used in Muncie Indiana before still has good prices and is like a old time parts store.
