Always wanted a diesel truck and this '06 Crew Cab Longbed Dually was too good to pass up.

The good:
- Price
- LBZ
- Interior condition
- Bone stock
- Was part of a tow fleet for a drift teams trailers so it was maintained well
- All new stainless brake lines
- Great tires, powder-coated wheels

The bad:

- Rusted rockers (rust belt problems), and peeling paint
- Siezed turbo vanes
- 5 bad glow plugs
- 350k miles
- Fuel leak (need some suggestions where to look)
- Coolant leak (already can see it's at the heater core connections)

So I JUST finished building a '96 1 ton, when I bought this truck last week. A link to it's build thread is below:



I wasted no time tearing into the LBZ and got the turbo off this weekend. An absolutely miserable job, but doable.

I know some of you will call me insane, but I'm pulling the transmission next. I should have done that from the beginning because busting those bolts loose on the up-pipes was not fun. Had to do it from the passenger wheel-well. Since I'm in the rust belt I broke 6 of the 12 bolts. 3 in the turbo, 3 in the exhaust manifolds. :(

With the trans removed everything is right in front of your face. I'll take that trade off all day.

There was a huge mouse house in the valley along with 20 years of general filth. This was after I'd already cleaned a bit.

Much better

Here's the parts list I have so far:

- Both thermostats
- Thermostat gaskets
- Breather re-route
- Heater core hoses
- Turbo heater hoses
- Drain back gasket
- Transmission filters and fluid
- Turbo rebuild kit KC turbo
- VGT solenoid KC turbo

I'll be towing a 5th wheel camper in the summer with this, so I'm trying to balance needs vs wants. REALLY all I need to do is clean the vanes and put it back together, but I do think an EGR delete and breather re-route would be smart.

I have HP tuners and can flash the PCM if I delete EGR.

Suggestions?

Welcome to the forum. Helluva truck. I'm not sure how many diesel guys we have lurking about, but I'm a fan of EGR deletes and good breathers. I believe it's better for an engine to not re-ingest it's own gas, but I'm not an engineer. Not sure what a re-route of the breather on a LBZ entails. Good luck however you decide to proceed.

Here's what I ended up buying:

- Both thermostats
- Thermostat gaskets
- Breather re-route
- Heater core hoses
- Turbo heater hoses
- Turbo/exhaust gasket set
- Intake gasket set
- Transmission filters and fluid
- Turbo rebuild kit KC turbo
- Oil /filter
- Air filter
- Merchant auto glow plug socket
- Glow plugs

Kinda surprised the truck doesn't have a cabin air filter.

The AC didn't seem to work either but that can wait for now.

Nice! Yeah, cabin filters were only on the 00-02 models.

I thought there was an aftermarket kit to add it though? I can't recall?

Is that truck a 4x4? If so, maybe a transfer case fluid replacement is a good idea? Same for the differential(s)?
