I was doing some routine maintance on my ctd today and when I went to drain the crank case breather bottle there was of course a little oil but unfortunatly their was also a little bit of antifreeze. not much, about 1/3 of a shot glass. The last time I changed oil which was only about three weeks ago I didn't notice anything but oil in the oil pan. I pulled the dipstick and carefully looked it over in the sunlight and it looked like pure oil. I cleaned the bottle real good and put it back on and plan on checking it in a week to see if any more finds its way in there. I am still covered by the 100k warranty. When I bought the truck I looked at the oil on the dipstick to see if it was discolored or milky and it wasn't and still isn't. If I had a major coolant leak wouldn't the oil be milky looking? Has anyone else ever had this happen? If I do have a problem how long will it take for me to notice. I'm assuming if antifreeze is where oil is supposed to be the engine should get louder and will sound funny? I've never been around an engine that died of this problem before. If I find more antifreeze in the bottle I think I already know the answere to my questions. I'm probably looking at a rebuild or a new engine huh?

 

Thanks for the replies.
I did as haulin in dixie suggested and let it sit for a day and a half then pulled the plug and drained some oil into a clear pan. No sign at all of any antifreeze only oil. I think I might get an oil sample kit though just so I can be sure. That was the first time since I got my truck that I cleaned the breather bottle so I hope it was from a wash like infidel suggested.

 

Thanks bama I never thought of that! I got an oil sample kit from my local deere dealer for nine bucks. will mail it tommorow. I'm really glad I found this website. I'm new to diesel pickups and really appreciate all the info and ideas.
Thanks
