Milky color oil under fill cap?
I have a 00 Durngo with a 4.7L. I change my own oil. When I was draining it, I did not notice anything wrong. When I went to fill it, there was a white milky substance under the cap. I thing that gets me is that it doesn't show on the stick. The dealership said that it was just condensation. Has anyone else come across this? I am a little worried that it might be a head gasket or something. Any info would be great.

I had the same problem with my 01 4.7, the dealer said these motors are very hard on oil and to follow the recomended change intervals. Everything was like they said until my wife went 1500km over on 2 oil changes in a row and it came back a little bit. Mabye the dealer actually told the truth.

Problaby would have you intake manifold gasket checked. Read either on this forum or from another forum a long time ago that Chrysler had a TSB on this. Antifreeze can slowly leak into the oil and eventually seizing up your engine! And the leak is mostly internal so you will not be able to visibly see anything outside the engine. I think another user in this forum posted something about this also.
So it would not matter even if you change your oil every 3k using synthetic, if it continues to have some abnormal coloration to your oil when you change your oil, better get that gasket checked or you will soon be out without an engine.

It's what saydee said, it's emulsification of the oil. It has to do with the oil filler being on the front of the engine, during cold weather the filler is exposed to cold air and that causes condensation on the inside of the filler neck. Nothing to worry about, but get that other filler cap.

Don't sweat the milky color oil. I get it sometimes on my motorcycle when I ride on short trips. It is most likely just condensation in the motor and when you don't run it long enough, the condensation doesn't have time to evaporate giving you the milky residue.
