sounds like no problem maby! milky white is condinsation, running too cold, not much heat at heater i bet needs thermostat, to burn off moisture, oil light ,change to high mile oil like 10/30 or higher to cure oil light flicker ,at idle i hope and not at speed

Right, it might be just the oil seperating/condensation from too many short trips that is on your oil cap. You did say you drove 40mins. but if it was a headgasket you would have a chocolate milkshake. Does your car run properly otherwise? Since your oil light is coming on your low on oil, so I would do an oil change and see if your symptoms go away.

The MK2 oil pressure monitor system is notorious for sending false warnings. My 85 Jetta would buzz repeatedly at low RPMs even though I had fresh oil and my guage read good pressure. I believe VW issued a TSB to change a resistor in the instrument cluster to recalibrate the warning buzzer detection.


last time my oil was Milky white, the Head had corroded away, letting Coolant & Oil mix. car ran strong, but recognised the problem & pulled the Head. recommend you do the Same.

Thanks for the feed back, so about my heater that works good but my air conditioner does not work I don't know if that has anything to do with it an I also just did change to 10/30 oil. The milky white stuff is pretty thick so someone told me to put sea foam in where I put my oil so I did that an now im just going to see what happens. If anyone has any other thoughts about what it could be please let me know. An my car runs pretty good im just concerned about the white stuff.


Sea Foam acts as a will also dilute your oil...I would only use it right before an oil change...and don't drive anywhere while it's in your oil. Be don't want to be buying an engine.


don't take too many short cuts. get a Compression check. get a mechanic to remove the cylinder head to look for damage. Milky Oil means coolant & oil are Mixing
