Diesel in my coolant tank?
 

I just checked my coolant and found it FULL of diesel fuel? The truck was running fine when I shut it off. its got 230.000 miles on it and hasnt givven me any trouble. What do I do to fix it? Cost if I do the work myself? I just got laid off this couldnt come at a worse time!!! ugh

I see a 2008 F-550 as your truck? Or do you have a 7.3?

Diesel in the coolant is a cracked injector cup or lifted injector cup.

NO sorry, the 550 was a truck the I drove in Afghanistan (armored) which is how I found this forum. I own and drive a 2002 350 with a 7.3. Do I have to pull the heads off to fix this? I heard a horror story about the cab having to be pulled off a ford truck to get the heads off? Im hoping this isnt my truck...:scare2:

there is a special tool to removal/install tool to do them with the head on

its ford 6.0 that the cab or engine needs to come out get the heads off

No need to pull the cab on our trucks...

And no you do not need to pull the heads off to fix an injector cup. You need to remove the valve covers, pull the injectors and the cups are what the injectors sit in. I do believe you need a certain tool to get the injector cups out but CSIPSD would know way more about that than I do.

the tool looks like a big tap you screw into the cup where the injector sits and you pry them out

the install tool looks like a injector, red loctite if i recall to hold them in

need to drain the coolant and fuel system before removing the cups

delco diesel okla city ok charged me 600.00 to fix mine you can buy a tool from whitaker for 300.00 goto their web site for inj cup removal tool and utube watch him do it

I think Clay @ RiffRaff has the tool you need and the cups as well.

From where can You order new cups to change them?

Give RiffRaff Diesel a call, thats where I get most of my maintance stuff from, because he packages it just right so I can carry it with me...

Riffraff Diesel: Motorcraft Injector Cup

I was thinking about just pulling the heads and getting rebuilt heads (exchange). That way Id start fresh with new everything up top. I have 250K+ on my engine and it just seems logical, I found a place where I can get re man heads for $400.00 each. Is this job super hard? Will I need special tools of any sort for head change? Any upgrades I should do while im at it? ( I am bone stock and dont have any $ for racy stuff).
Thanks in adavnce.

No reason to do this... I have seen trucks with 550-600k and the factory motor.

Replace the cup and move on.:tu:

So youre saying get the special tool and the cups and replace them with the heads on. What is your recommendation with th injectors? I believe I need glow plugs as its hard starting when cold. What else should I do while Im in there?

Never a bad idea to replace the glow plugs while you're in there.

What about the injectors?

id recomend new glow plugs and under valve cover wire harnesses, odds are after seeing the heat and oil from that many miles they are going to be stiff and brittle and may end up getting damaged during removal or re-install.

would a bad injector cup be a cause for a rough idol or miss? i dont have diesel in the coolent though.

Might be a symptom, but that to me is more an issue with injectors or o-rings.
