I have a 90 F-150 302. Last winter I started noticing a little
milkiness on the dipstick. It went away in the summer. It's doing it
again this year, and I am loosing some coolant. When I stop the truck I
can smell coolant (a little) but can't find where it's going. Head
gasket? intake manifold gasket? Is there any way to know before tear
down? The truck does not overheat. In fact it has always showed
uncomfortably low on the temp guage. I never checked whether it was the
thermostat, or the guage. I'm hoping someone will tell me the moisture
in the oil is condensation from running the engine to cool.

The is a good chance that the milkyness you seen is from condesation
in winter in a rngine that never heats up properly which is likely due
to a a bad thremostat. THis is confirmed by the fact that you only
see this prpblem in winter when engine is cooler. Replace thermostat
and see if it clears up of not before you worry about it any more.

If it is going through a cylinder, then when you pull the plugs that one
plug will be super clean. If the plugs are all dirty, then the head
gasket isn't as likely the leak spot.

hi-1. A radiator 'stop-leak" added . 2. A new-hotter
thermistat put in. 3. Check for water getting in thru the
dipstick or the oil-filler caps.

Water in your oil could mean engine damage from one or several locations...
something as simple/complicated as a head gasket.... does your oil get a
frothy chocolate like look and do you get a real white exhaust... just a few
things to check 'easy' to see perhaps where the water is entering your
system..

Take Care

Check the crankcase vent system (PCV). What kind of driving do you do?
