Ok. I know this was discussed about a month ago here http://www.naxja.org/forum/showthread.php?t=50045&highlight=2000+oil but rather than revive that thread I have a few different questions I will post here. The Jeep is a 2000 4.0 whith 69,500 miles and the 2000 is apparently plagued with junk heads. I have taken off the oil cap and looked for the leaky green with flashlight and didnt see any coolant but I have noticed a little bubble (where the red arrow is pointing in photo) a few times a minute, maybe. While I havent noticed coolant in the oil while changing oil I do possibly, maybe, notice oil in coolant (if that is possible). Im not sure if oil is in the coolant which was last flushed this past december or if it's just a little rusty. You can see from the photo that my warm idle is right around 500 rpm and my warm idle oil pressure hovers right around 20. What do you think? Does the little bubble mean I have a cracked head? the oil cap is a little slimy brown but... Im just not sure. Can the oil go into coolant rather than vise versa? If I do have a cracked head what should I do? It is not under any warranty.
