Evening All, I've been reading through the various threads and have been compiling a list of items on my 2005 6.0 that need attention along with a list of parts needed for the repairs. My question is what else should I replace while I am in there?

I have a long crank while cold issue and have determined that the dummy plug(s) are the likely culprit. I will replace the plugs and standpipes.

This Excursion is new to me and I don't know if the STC fitting has been upgraded. Watching the videos and looking at the kit, the replacement O-ring, to seal around the HPOP, is blue. Is this a valid tattletale as to whether someone has been under that cover? If not, then 1 upgraded STC fitting needs to be ordered.

Is am going to clean/anti-sieze the turbo while I have it off. I've read about an updated drain pipe and oil feed line, are these worthwhile.

I'm also going to do the "blue spring" update. Anything else here?

I've updated to the 140A alternator and will be upgrading the wiring, both on the positive side and also update the ground wires on the drivers side per the battery thread. Cleaning all grounds will also be addressed.

So I ask the brain trust here, any other items that I should look at while I'm into the engine this deep. TIA

 

I had a conversation with Ed at FICM Repair . com about this subject. There's a board in the FICM that evidently can and will play hell with cold starting. Something to check.

 

I did the turbo oil drain tube when I had mine out also, I bought a bunch of parts like you're doing but that is one part I felt wasn't needed and a waste of money.

 

Interesting, thanks for the info.

I've pulled the ICP sensor in the morning and had no oil this is supposed to verify dummy plugs or stand pipes leaking. Also while watching ICP, I'm seeing 85% until it sees 500 PSI and then it backs down to 25% or so at idle, IIRC.

The updated drain pipe supposedly has smoother bends than OEM. My initial thought was the same as yours, just wanted to be sure I wasn't missing something.

 

Being a 2005 Excursion you'll need to determine if it is a leftover 2004 motor or the actual 2005 engine.

The 2005 engine in a 2005 Excursion came out about March/April 2005. Look at your build date on the jamb sticker.

Build date of 5/05. Hopefully this is a good thing? Is there a known S/N split where they are verified 05 engines. Any other tattletales for the 05 engines?

I was looking at the STC fitting on Bulletproofdiesel's website and there was a disclaimer that it wasn't compatible with all 05 Excursions, that must be the reason.

 

My 05 ex has a 04 engine in it. Just look at the passenger side valve cover. Don't think they have the troublesome STC fitting just crappy HPOPs.

 

Do you know what your build date is per chance?

I'll check the valve cover, thanks.

 

May 2005 is a very good chance it has the actual 2005 6.0 motor.

From what I've seen when the STC fitting gives up, it gives up with no real warning. Definitely not a gradual thing. With that said, it's good to update to the one piece design when possible.

For hot start issues with 05+ engines:

#1 Dummy Plugs
#2 STC
#3 Standpipes
#4 Oil rail nipple o-rings.

Cold Start Issues 05+ engines:

#1 FICM
#2 Dummy Plugs

.....and not to leave out the 03/04 but basically the HPOP is #1 on both lists.

One easy test is before starting the engine first thing in the morning is to remove the ICP sensor and check the oil level. Should be near the bottom of the threads.

After watching a DieselTechRon video on YT, I did this exact thing. No oil in sight.

 

As they say "here's your sign"

Josh

 

LOL, Yes sir. Figured I would change the dummy plugs and standpipes, then air test for good measure.

Do I need to upgrade anything on/around the turbo? Oil feed line maybe?

 

Nah, if both are in good shape reuse them. Purchase the turbo install kit for new o-rings, gasket and bolts.

I just verified that the passenger side valve cover tag says 2005. I should be good to order the updated STC fitting, I'm assuming.
