Hey guys I was just wondering what the differences between the latest 6.0 vs the old one.? As I understand it the new 6.0 put in 2006trucks after January have the commonized engine similar to the new 6.4. Different heads I presume. Can anyone give me the lowdown on the changes on the engine. My curiosity bone has gotten the best off me.

 

Here you go. We might just add this to the Tech folder...

Subject: 2006 6.0L Diesel Power Stroke Cylinder Head Commonization
Effective Date: Ford Production Assembly Plants - January 11, 2006
Kentucky Truck Plant (Super Duty) & Lorraine Assembly Plant (Econoline)
Description
Changes are being made to the 6.0L diesel cylinder head, head gasket, crankcase block, rocker
arm carrier and injector hold down clamps for the 2006 Super Duty and Econoline Program. The
action is taking place to facilitate/communize the International manufacturing process for the
upcoming 6.4L program. The 2006 6.0L used in Ford vehicles after January 11, 2006 are being
referred to as "Commonization Engines".
Part number details are provided on a separate excel spreadsheet.
Figure 1 - New cylinder head
1. Carrier boss bolt holes M10 x 1.5
2. Injector clamp bolt holes (relocated)
The new cylinder heads have several casting changes including a slight injector clamp bolt hole
relocation (2, figure 1) and the carrier boss bolt hole size and location changes (1, figure 1). New
cylinder heads also use 32 mm cup plugs replacing the old 28 mm cup plugs.
The cylinder head gasket is also new to accommodate the new 20mm cylinder head location
dowels. Pre commonization head use 18mm dowels
Note: At this time the new cylinder head assembly is not interchangeable with the previously level
head.
Figure 2 – Previous Level Cylinder Head
1. Carrier boss bolt holes M8 x 1.5
2. Injector clamp bolt holes (original locations)
Note: The previous level cylinder head assembly is not interchangeable with the new head.
Figure 3 - New Block Assembly
The new crankcase (block) uses two 20mm cylinder head locating dowels per head.
The old crankcase (block) uses two 18mm cylinder head locating dowels per head.
Note: The new and old block assembly is not interchangeable. This affects replacement of all 6009
short blocks and the 6010 bare blocks.
Rocker Arm Carrier:
Figure 4 - New Rocker Arm Carrier
Casting changes to the rocker carrier provide increased clearance for new injector hold down
clamps (figure 6). The new carrier also uses only 2 bolts and locating dowels to attach the carrier
to the head.
The new rocker carrier is serviced in a Rocker Arm Carrier Kit which includes the rocker carrier
cover, gasket and necessary dowels.
Note: The new and old rocker arm carrier kits are not interchangeable.
Figure 5 – Previous Level Rocker Arm Carrier Kit
The old rocker arm carrier uses 4 attaching bolts to hold the carrier to the old cylinder head (figure
2).
The previous rocker arm carrier is also serviced in a kit which includes the rocker carrier cover,
gasket and necessary dowels.
Note: The previous level rocker arm kit is not interchangeable with the new kit and will remain
available for service.
Injector Hold Down Clamp:
Figure 6 - New Injector Hold Down Clamp Assembly
The tail end of the new injector hold down clamp is being reduced to avoid interference with the
rocker arm carrier wall. Injector hold down clamp bolt torque will increase from 24 lbf·ft to 25.8 lbf·ft
and bolt head size will increase from T40 to T45.
Note: The new and old injector hold down clamps are not in interchangeable.
Figure 7 – Previous Level Injector Hold Down Clamp Assembly
Note: The new and old injector hold down clamps are not in interchangeable. The old injector hold
down clamp will remain available for service.

 

so how about the 2007 engines?

 

Should be the same I presume until the new 6.4 comes out. Thanks for that long post Maxium. Yuo this should be in the tech folder. Im sure a lot off people dont know about these engine changes.

 

ok...now how about the 2005 6.0l, production date 08/2004, was that an improved engine over the earlier 6.0l's??? just curious, thanks

 

Here are the 05 updates over the 04

1.Deleted intake throttle – instead added air flow “directors” inside RH exhaust tube & intake manifold.
2 New air inlet elbow to replace the throttle
3 Replace Rexroth high pressure pump with Shepard pump.
4 Replace Injection Press Relief (IPR) screen with perforated plate style filter – allows finer filtration (150 vs. 200 micron).
5 Water inlet relocated on front cover to accommodate new steering gear
6 New fuel supply and return pipes to accommodate water inlet
position
7 Improved EGR valve, increased flow, required for emissions.
8 Intake Manifold, EGR Distribution
9 Turbo Upgrade for flutter improvement

 

04 Updates over the 03MY

1 EGRTP (EGR Throttle Plate)
2 High pressure oil rails - Increased volume and delivery system
3 EGR cooler - Redesigned
4 EGR cooler exhaust connection -Redesigned
5 Injectors - Redesigned
6 ICP sensor - (MSG) and relocated near the oil fill tube.
7 Camshaft - Duration, and lift
8 Pistons - modified
9 Glow plugs - 1.2 mm shorter
10 Water pump - increased impeller diameter
11 FICM - Upgraded
12 FICM brackets - multiple pieces and larger isolators
13 GPCM bracket - modified
14 Intake manifold - Modified
15 Crankcase breather - Moved
16 Crankcase breather hose
17 Compressor inlet hose - Because of new breather
18 Turbo - 3 additional fins/270 thrust bearing.
19 Turbo mounting backet
20 Stand pipes - Because of new high pressure oil rails
21 Branch tube - goes with stand pipe
22 Rexroth pump - More pressure
23 Glow plug wiring harness
24 2004 MY emissions labels
25 Cylinder head - External boss
26 Rocker arm carrier
27 LH valve cover -Because of breather
28 RH valve cover - MSG ICP
29 Engine wire harness
30 LH exhaust manifold - clearance on E-Series

 

Almost be worth making this thread a sticky- lots of good information, and it gets asked frequently.

 

So a 2006 bought in summer 05 the same as 05? Also it sounds like there has been a lot of improvements since 03, right?

 

Maxium4x4: do you have the updates to current? I know of a couple I've read about: new head gasket (was that for the whole MY '06?), the machining done to the turbo to help prevent the sticky vanes (I think that was at the end of '05, again '06 MY), and the HPOP oil line change to get rid of the high pitch vibration/noise (should have gone into motors this last July or so, '07 MY). Anything else or do you have better info on when these happened?

 

I have added this thread as a link in the 6.0 Tech Forum.

Thanks Max for the info...keep it comin'

Can we get an answer to this, I too have an August '06 PSD which appears to be the late '05 engine I take it?

 

I think the engine also has a build date? I am unsure of where to look or how to translate.

 

Drivers side valve cover located on the FICM you will see a sticker with the date of your engine assembly.
