I have milky oil on the tip of my dip stick. Does this mean my head gasket is starting to go? I will post a pic later.

 

Well that means water is gettin into your oil, as for your head gasket, im not to sure, but that is a very big problem. It could be any number of things causing water to mix with your oil

 

most likely. that means you have coolant in your erl. does it over heat really quickly?

 

It can indicate a head problem but it could also mean that there is some condensation building up as well. I've seen it where it is NOT head related.

Questions:

1. How often do you change your oil?
2. Do you take a lot of short trips? Short trips can lead to a buildup of moisture due to the fact that the engine doesn't get hot enough to burn it off............

 

Compression Test.

maybe do a block check, see if there's any combustion gases in your coolant

 

sounds busted to me, change the oil and see if it is all that color

 

It is not over heating , or running bad, or smoking . Just this milky stuff on the end of the dip stick . The oil is 10w30 casteroil synthitic blend. The 3erd pic down I just stuck the dip stick in to touch the top of the oil in the pan. I do take alot of short rides in the jeep. I changed the oil in june 2010.

 

How many miles since last change.

And it may be the Paraffin separating, dont freakout yet.

 

Maybe 500 to 1000 miles since to oil change in june.

 

Check your air filter and see if there is any in there also did you go wheeling in any water...Tj

 

I will check the air cleaner, I have not been wheeling in the water. I did hose the motor down many times when I bought the XJ in june. The motor was VERY dirty.

 

The milky stuff can be seen in the dipstick tube also.But not under the oil filler cap.
