First is your truck or company truck? If it is your truck you can buy a combustion leak tester for about 45 dollars and test the coolant for combustion gas if shows combustion gas in the coolant then you have a cracked head, bad head gasket, or problem with a liner. I am dealing with the same problem as we speak Detroit shop just put a new head on 2 weeks ago and changed all the coolant and now we have combustion gas in the coolant again so they we have a bad liner somewhere. So now Detroit's now sure what their going do with it but it's under warranty so I am not to worried at this point. If you are getting coolant in the oil depending on the amount of coolant it will ruin the bearings.
