oil in coolant

  1. 99-03 7.3 Motor Problems
    Let me start off by saying my 7.3 has about 340000 on it and has pretty bad blow by already. Like a train so I already assume the engine is on its last leg. I'm not the original owner so I do not know how the previous owner treated it but I dont think very well. I recently moved from ky to MI...
  2. 99-03 7.3L General Discussion
    So I have a 2001 ford f 350 with a 7.3L Diesel engine. I recently bought it after it had sat all winter(I live in Alaska). The guy that had it before me had quite a few mods installed in it so if you need the list just ask. My main problem is that it would just stall and die. I found this out...

  6. 6.0 Motor problems
    Noticed a few weeks ago truck has oil in antifreeze, just confirmed the other day it's going both ways oil is contaminated as well. From research I've done more than likely oil cooler. I have priced that part, and only comes with o-rings for oil cooler case, and oil cooler itself. Know I will...
  7. General 6.0L Discussion
    i have residual oil in my coolant tank after my mechanic replaced head gaskets, oil cooler, and egr cooler. He spent some time flushing the coolant system but we still have some oil. I added an aftermarket coolant filter system. Is that enough or am I asking for problems with my new oil cooler?
