After reading through a number of links on here it seems I have to admit to a blown headgasket don't I?

you betcha. Although I have seen intake manifold gaskets do this as well. In particular the gm motor- 3.1 liter. Continued driving of this will likely kill the bottom half of the engine. DON'T DRIVE IT!!!

Thanks Paul, it was a gasket. My mechanic is away for another ten days which is just killing me!

The other mechanic I took it to told me there was no harm in driving it but I didnt really believe that so I found a Ford forum and posted there. The reply was similar to yours plus a few other problems that could happen if I continue to drive it.

I hope I haven't ruined it already.

Anyone wanna buy a car?

Jo, While your waiting for your mechanic, drain your oil, leave the plug out overnight. Put the plug back in add 2 quarts of oil to flush some residue out, and drain again. Re-istall the plug again and add 4 quarts of fresh oil. You should not be running it at all. When your guy is back have it towed there. And ahh.. No Thanks on the "new car"!

Well, I live pretty far up north, and I see alot of that (oil looking milky) that can be from water in the oil. I notice this happen alot in winter (well, all the time because where I live there is only 3 months real summer anyway) So it gets cold and freezes. I've seen oil look like coffee when you put the whitner in. Pretty weird, eh?

Milky OIl appearance is generally caused by condensation in an engine. This happens when you drive a short distance. The water from the crank case is not burned off. This is normal. Just get her good and hot and this should cure your worries. I know that this is a scary sight because you automatically think head gasket and $$$$ but if your driving habits in cold weather don't allow for a hot engine then this is your problem.

Especially on the dip stick and filler cap interior.

Could be water or antifreeze getting into the oil

A cracked radiator will NOT put water in the engine and make the oil milky. A bad head gasket WILL put water in the engine and make the oil look milky. That does not neccessarily mean you have a bad engine. Have someone fix or replace the radiator and replace the head gasket. It could be a good engine for a long time yet

You would eventually find water in the oil, or it would look milky compared to normal oil.

That would be moisture in the oil.

yes it can water can leak into the intake valley and get into your oil resulting in milky oil
