iceman Posted August 16, 2008 Share Posted August 16, 2008 just showed up yesterday 6.4 13500 miles and oil all in the degass bottle not like the 6.0 like a pudding sludge just nasty black oil has anyone encountered any one of these yet Quote Link to comment Share on other sites More sharing options...
Jeff_ Posted August 16, 2008 Share Posted August 16, 2008 Some 6.4's have had a problem with cavitation behind the water pump allowing oil and coolant to mix. Usually when this happens you will find coolant in the oil as well. If you drain the oil and some coolant runs out you'll prolly be doing a front cover replacement. I guess I wouldn't rule out the oil cooler either, but on a 6.4 with this concern I'd start by pulling the water pump and taking a close look.

Jeff_ Posted August 19, 2008 Share Posted August 19, 2008 Sweet, If you get a chance could you post a picture of the cavitation so those who haven't seen it before know what it looks like? Quote Link to comment Share on other sites More sharing options...

slim Posted August 20, 2008 Share Posted August 20, 2008 I could see coolant going into the oil but probably not the other way around. I don't think there is pressurized oil behind the area that has cavatation issues. Quote Link to comment Share on other sites More sharing options...
