w250_93

I bought my truck in march of 06 its a 93 w250 and as I was checking all the fluids I noticed that ther was oil in the radiator so I figured that the truck had a blown head gasket but there wasn't any antifreeze in the oil so I just let it go cause the truck ran fine well a couple weeks went by I checked it again and the antifreeze was low but again there wasn't any in the oil so I just added some water and let it go then I stated thinking about the oil cooler and after pulling a load one day I noticed that the front axle case was covered in antifeeze so I looked to see where it was coming from and sure enough it was coming from the oil cooler so what it does is let oil in the antifreeze and lets antifreeze leak out and I was wondering if any of you guys have had this problem before and what parts I need to fix it and maybe some instructions if possible but other than oil being in the radiator and leaking antifreeze(only when I pull a load and get it hotter than normal) the truck runs like a dream.
And Also i'm going to be buying injectors when I get the money and I don't care about dirty exhaust so i'm considering pod's is there anything better for a similar price or could I just take the tips out of a second gen set and put them in my bodies. and one more question, I have a hx35 that needs to be rebuilt and the shaft is broken will the shaft out of my h1c fit in the hx35 if I rebuild it and would it be worth it.

Thanks for your help and sorry for the length of the post

Ummm....fix your heat exchanger before you throw money at anything else. You're talking about the the "can thing" on the passenger's side of the engine mounted low close to the exhaust down-pipe, right? If it's leaking now, it will leak more and more and more later. Have you checked your transmission fluid to make sure you don't have coolant in there? You can get aftermarket water/oil heat exchangers from places like Jegs or Summit Racing. I think a replacement OEM unit is hard to find.
