6.0L needs help

[2005powerstroke]

I originally posted about fuel in the oil and another member replied with injector cups. What are injector cups? Or a cracked head. How do I tell if it's a cracked head or injector cups? Any help is appreciated. Thanx, Chris

You'd probably have to pull the cab to find a cracked head.

pull all 8 injectors, pressurize the cooling system, and spray soapy water onto the cups and check for bubbles. in my experience 8 out of 10 times the head is cracked and needs replacement. the cup is what the injector fits into in the head and the injector orings seal to.

If memory serves a cracked head is the only way a fuel in the oil scenario can arise in the 6.0

Keep me honest here......we're talking about fuel in the oil. Not fuel in the coolant?
