My dad has a 2005 dmax with a lil over 300k on it. He was coming home last night and noticed a lil drop in the oil pressure so he got home checked the oil and its super milky. We changed the oil and filled up the coolant. as soon as i fired up the truck it sucks the coolant as fast as i can put it in. I shut the truck off and the oil is filled with coolant again. From what I have read on this site is that dmaxs will not put water into the oil from a head gasket. Is this true? If so what else could be the issue with coolant getting into the oil?? Thanks in advance..
There are no signs of it being the head gaskets. The upper hose stays pretty soft when running and about a min after I shut it off its really soft. Is there a way to check the water pump seal without teariing into it? Thanks for the help
