diesel rookie in need of some help

[Phil's f250psd]

O.K. all you diesel pros here it is.

I've got a 99 f250 7.3 early model recently it started running a bit rough and while looking for the problem i found diesel in the coolant. Today i removed the valve covers and harnesses look pretty good for 270000 miles. Although the plastic retainers that hold the wiring to the gasket are weak and breaking the wiring seems good. the passenger side might have been slightly unplugged and i will ck this when i reinstall. all the injectors ohm between 3.0-3.2 and i plan to replace the glow plugs while i'm in there. now the hard part removing the cups without pulling the heads. you guys have been a wealth of info so does anyone have the tools their willing to lone i'm in texas near Houston and could use some help. anything i might be missing or should ck. i plan to ck codes when its running again but for now cant give you any info on that at this time.

I am not an expert on Powerstrokes, but I have found that problem on a few of the John Deere and Cummins engines I have worked on. Im my experience so far, I have found that either someone has put a bit of Diesel in the coolant, or they have blown a head gasket. Again do not quote me on this, someone with more knowledge on Powerstrokes will chime in. Although normally its oil in the coolant, sometimes the gasket will blow on the inside. This will cause it to combust only some of the diesel and blow the rest into the coolant lines that run through the block, therefore resulting in poor operation (running rough, starving itself of fuel) and then some. Worst case is that there is a slight crack in the block. Wish I could be more of a help, but thats all I know for now.

I had a problem with diesel in coolant. I was told by dealer and several techs on this site that the only way to get diesel in coolant was the cups in the heads. they are brass and erode. These brass cups house the injector and are pressed into the head through the water jacket. Mine was to the point that diesel was purging out of the degas bottle . I had about six inches of diesel in the bottle. There is a way to replace the cups without pulling the heads, however my local for shop (dealer) wouldn't do it. They sold me a set of re-man heads. My truck ran the same both before and after the incident. Only indication of a problem was diesel leaking from the degas bottle. Hope this helps. good luck!

thanks for all the help. ive got all the injectors out and 6 of the eight appear to have leaking cups. the injectors are discolored quite bad with the other two still looking pretty new. all ohm good however. still looking for someone to possibly borrow the tools from. or maybe a place to purchase them cheap.
