No problem on the service and thank you for noticing. I certainly will give clay a call. If anyone as remotely close to sumter sc and wouldn't mind a hand, it would be appreciated.

 

Help is on the way! First go here:

This is the link to FTE's VetNet. A great group of retired and active military that loves old fords. We will welcome you in with open arms.

These two links should help you get the help you need now, and could help your family when you're deployed.

Thank you for your service. And get ready to hear it quite often.........

Welcome to FTE!

 

Lookit - if you are reaching out to me, is the problem unresolved at this point?

I'm seriously thinking blown head gasket right now. I hate to seem negative, but the mixing kinda looks like that.

International based engines like the 7.3 are notorious for that exact thing, they leak from all four corners sooner or later.

Can you find out what the exact fluids are in the top and bottom seperation layers?

You know as well as I do that the fuel can't get into the coolant at that volume. Even if it did it would get churned into a chocolate milk looking stuff. We need to determine exactly what that stuff is.

(SUBSCRIBED)

QUESTION: Is there a mechanical fuel pump on the side of the block involved?

I already know - it's a dumb question.


We need to identify what those two fluids are and where they came from. That's the beginning right there.

i can't tell exactly what that is, and has anyone so far taken a sample from the oil pan?

I'd say drain the oil and look at it.

Green don't mean diesel - it looks more like antifreeze. The brown at the bottom could be rusty water, but it would mix. Since oil floats on water, that can't be anything but confusing.

Look at it in terms of practical realities - what stays seperated from what?

I grant you that oil will float on top of water, and diesel is oil, but where can fuel get injected into the water jacket?

That's the bee that buzzez my bonnet...

i do not believe it is possible!

Do they have an auto crafts shop available at their post with an experienced man to advise them?


You and I can speculate forever, but a good man in the right place can figure it out. TRUE?

It's high time to ask the manager of the local on base auto hobby shop for his own opinion. We can't make sense of it any other way.

~ and they are there to help our people out


My advice is therefore this:

GET IN TOUCH WITH YOUR MWR SPONSORED EXPERT MECHS, they know their stuff, or they would have been fired long ago

~They only hire the best. Usually old time hot-rodders.

 

To find a bad injector cup you need to pull all the injectors and pressurize the coolant system. About 15-16 PSI should do. Look in each injector bore. Coolant welling up or leaking past a cup is what you are looking for. The reason you get fuel in the coolant is that the fuel pressure is about 4 times what the coolant pressue is so the fuel leaks past a bad cup and into the coolant. Look at them all closely. There is the possibility you have more then one bad cup.

 

I don't think I ever want an engine designed that way....

(HONESTLY SAID)

 

well this is what I do know, the yellow layer on top has the smell and lubrication of fuel. I had to wait for it to completly sepearte to be absolutly sure. I have no tell tell signes of blown headgasket. Still cranks and operates normally. What i do know is that it has been a couple months sinse i have popped the hood to check everything out. The only reason i noticed it to day is because the fuel has been in there long enough to start deterriorating the rubber seal on the radiator resviour cap which finally gave out under the pressure from the system as I parked the truck and started walking in the house, spewing the slime onto the ground under the truck. Hopefully it is without a doubt only the injector caps and no other problems. But I will definatley keep the head gasket in mind as I inspect everything.

 

CONFIRMED,

I don't ever want one of those.

 

Head gaskets are pretty rare on these trucks, Injector cups, definately more common.

 

Hi Chad and welcome to FTE. I live up in Rock Hill, If you need a hand with it we can try to set somthing up.
