The creamy emulsion is usually caused by water condensation in the crankcase. It's relatively harmless. Short trips will not boil off this water. Clean the cap and filler tube, then go for a long drive to clear the water.

If the "mayo" remains after long trips, check for oil in the coolant tank. . If there is you have a leaking oil cooler. It's buried between the cylinderheads in a coolant gallery. It will require replacement of the cooler, and flushing of the cooling system. Continued use will clog the radiator and heater core.

If there is no oil in the coolant tank, with the engine idling, check the tank for exhaust gas smell and signs of bubbles. If there are it's likely you have a blown head gasket. Not very common for this engine but it does happen.

I think they should switch to one of the other style forums... they are free and about 10x better for the users... I personaly hate the way this forum is set up...

Check out the Omega Owners Forum to see how much better it is...

I'm starting a separate discussion regarding the Forum. It's rude to hijack someone's thread this way.
