Truck Repair: n14 cummins with coolant in the oil, n14 cummins, mechanic work


Question
I recently did an oil change and flushed and change the coolant in my truck. I use fleet guard coolant flush. Now I have coolant in my oil. It seem to be a lot too.  I have done a lot of mechanic work for gas engines and some automatic Trans overhauls. I think I can take on a new task. I would like to have some I deal what I might be dealing with and what specialty tools I might need to get.
I would appreciate any and all help.

Answer
Has the coolant mixed with oil forming a milky gel?. If so, then you need to check your liner sleeve "O"rings for ct or pitting or probabaly a cracked liner. Replace as necessary.
If you have raw unmixed coolant in oil you need to check the following:
1. The waterpump oil seal may be leaking oil into coolant.
2. The oil cooler may be leaking as well

Hope you find thi useful.
