Ok so I've lost some economy and power. noticed smoke from under the hood at startup. found the gasket between the exhaust manifold and turbo is blown. goina pull the turbo to replace the gasket. ordered the turbo down with cat delete 2 piece pipe to do at the same time. Was planning on doing the oil crossover whilst in there.
Any other mods I can do that would take advantage of this down time? While the turbo is off?

TIA,

Jason

I'm assuming you are talking about the donut gaskets that are bad. Make sure you get new up pipes as well because the up pipes are typically all worn and galled up and won't seal well even with new donuts. Slather the donuts and mating surfaces with antisieze when it goes back together.

well I'm not certain if its a dohnut gasket. the mating surface appears to be flat. i've not had a turbo off before. looks like dohnuts only on the downpipe to the cat. I'm leaking between the header pipes to the turbo...guess you could classify that as up pipe?

where do I get the o-rings? I asked the local regular parts place and they had no idea. We have a NAPA but is 30 miles away. Are the dealer prices on these parts affordable.
I'm sort of in the country. But there is a dealer only about 5 miles away. I want to be able to tackle this one this week and hopefully not wait on parts. I drive this sucker daily.

ford has the o rings in stock, at least where i am. do you have an international dealership around you? im sure they have them there, and probably a little cheaper than ford. and as far as i know, these are a dealer item only. good luck:thumb:

As GTS said it is probably your up-pipes leaking not the flat gasket or baby's butt collector. If you are worried about down time and getting it fixed I would suggest buying new up-pipes, donut gaskets, pedestal o-rings and up-pipe bolts.

I have reused the gasket on the collector to turbo before and have never seen one leak.

While the turbo is off I would suggest gutting the EBPV and swapping the pedestal to a modified one.

Do you still have the orange intake boot that goes from turbo to aluminum mounting piece? If so, I would get the updated version and junk the orange boot, they are prone to leaking.

Well attempted to perform this work this weekend. I had soaked everything the day before and pretty much everything came off fairly easy. I made a 15mm shorty wrench for the left nut on the collector. The pedistal bolt that is next to the EBPV was crazy tight. I broke 2 10mm swivel sockets and 3 1/4" universals. Tried Impact and breaker bar. Could not remove it. I'm ordering an implact 10mm swivel to see if i can get that one bolt off. I have a good Ingersol Rand impact gun. Not a cheapie Would Not budge until the sockets or swivels broke.
It was indeed the up pipes leaking so I tightened them up. Re-installed everything. also performed the 3" downtube and Cat delete while in there. Power is way up. I now have turbo whine. The increase in power is very dramatic. I used to struggle pulling a 6X10 trailer with a few bikes and our mule in the bed. No problem now. Time will tell on the fuel economy but it was worth the effort. Turbo does not have slop and spins easy to i'm feeling good about that.

I know this is an old thread but i figured it would be the right place to ask. On the pipes between the manifolds and cast y pipe the turbine housing bolts to. Up pipes i think they're called. Are there any gaskets and where would i find replacements if there are? I'm going to be putting my egt sensor in te drivers side up pipe im thinking.

There are "donut" type gaskets between the uppipes and the turbine y-pipe. You need to make sure that the uppipes are not eroded (from leaking exhaust) where the donuts will ride on the pipes (otherwise they will leak again). If they are arodes, get new uppipes. There are no gaskets where the uppipes bolt to the exhaust manifolds. Here's some part numbers:

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

Turbo Exhaust Inlet Gasket (between turbo inlet & collector)
(Ford) F4TZ-6N640-B
(International) 182210C1

Turbo Exhaust Up-Pipes
(Ford) F4TZ-6K854-A (Driver’s side)
(Ford) F6TZ-6K854-A (Passenger side)
(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!

EBPV- Exhuast Back Pressure Valve

A modified or deleted pedistal is one that does not have the cylinder on it where the rod comes out of. Look at the link below and you will see the difference. I like the idea of the deleted pedistal as opposed to just cutting off the cylinder and welding, I have read where oil has leaked after welding it. With the deleted pedistal there is no worrying about it leaking, it is casted without it.

This is the pedistal I bought- Replacement O-rings for Ford Diesel Engines It shows it's out of stock, there are other places that sell them though. Beans sells them- http://bdpshop.com/power-stroke/199...troke-non-complex-turbo-pedestal-no-ebpv.html

Dieselorings.com is where I bought my o-rings from for the pedistal and the metal gasket where the up pipes meet the turbo.

What is the benefit of deleting the EBPV?What do you do with the butterfly that the rod goes to?
The benefit is preventing an oil leak or I have read where the butterfly gets stuck shut. Oil will leak around the rod where it comes out of the pedistal. Plus I think the EBPV is just a stupid idea, I hate it. To get rid of the butterfly you pull the part of the exhaust housing off where the downpipe meets (3 8mm bolts) it and you grind the two rivets off the butterfly and pop the butterfly out and I can't remember how the rod it is on comes out now, but it does and you plug the hole with a freeze plug or you can put a pipe plug in it. You can also buy that piece that is casted without a hole, but I think I paid like $.19 for a freeze plug, you can't beat that.
