injector sleeves

well following my previous thread a week or so ago, I do believe that is IS in fact fuel in my coolant reservoir. In the previous thread i was told it was injector sleeves. They said to drain the coolant, refill with water and double check it is fuel.

what all is involved with replacing the injector sleeves. its a bummer since i had the valve covers off just a few weeks ago replacing the glow plugs. where exactly are the injector sleeves located and is there anything else that should be replaced while the injectors are out, for example injector o-rings? lastly, where can I get all of this stuff for a reasonable price and is it feasible to do myself?

thanks,
Nic

Its a pretty involved job, you can narrow it down to which side is leaking by pressurizing the coolant tank, and removingthe fuel lines from the filter bowl(on the right side). Which ever one is leaking air bubbles will show which side you need to investigate. Hopefully it is in the front which will make it much more enjoyable (hah as if it was). In short, the sleeves (cups) are what the injector is down inside of. It has holes in it's perimeter that allow fuel and oil to come in and go out. It is surrounded by engine coolant and when one leaks, the fuel pressure is higher than the 16psi the cooling system is under, and that's how it makes its way back to the tank. They are loc-tited in, and there is a special tool to remove them. I think you can use a stock junk injector, or there is a "dummy" that is used to seat the sleeves in.

basically, im tempted to have it done somewhere for the fact that i have little time as it is

i also do not have a junk stock injector to seat the sleeve with ... are you saying that only the bad sleeve needs replaced?

guzzle-thank you i really apreciate it

but after seeing that i think i am just going to take it somewhere so they can just have it done in a couple days ... hopefully im not looking at too much in labor + parts

am i doing damage to my engine by driving with fuel floating at the top of the coolant reservoir? i think when its hot it gets too full in the reservoir and leaks some of that fuel out, hence why my truck smells like fuel, smells like fuel when i turn my heater on at first, and why my battery on pass. side and the hood blanket right about that are wet

With fuel in the coolant, you will be risking cavitation on the cylinder walls and could result in a pinhole through the cylinder wall. No fix for that, just a new block.
What you are seeing in the tanik is what is separating out, there is still a lot of fuel that is still mixed throughout your system.
I can't say how long that would take but any cavitation is more than I would want.
Most of the seals in the coolant system are butyl-N and will swell when exposed to diesel fuel so there are many places that could leak prematurely.

If it were me, it would be parked until it could be fixed.
