after i checked it, after having changed the oil after the winter, it didn't appear to be green, but more like the grayish-white you are mentioning... i didn't peak down into the cover though, i'll take a look.

If you have water in the oil, you will see it on the dip stick as well. Plus there would be an abundance of the off white liquid sitting on top of the oil you drained in the the catch pan. It may or may not have a green, blue, orange or what ever tent depending on the color of your coolant.
Good luck.

Let the motor run long enough for the exhaust manifolds / headers to get good and hot. Pull dipstick and place a drop or tool on the hot exhaust. If it only smokes and disappears you are good. If it boils and smokes. you have water in the oil and are not good. Water in oil will form an emulsion which gives it the white color you sometimes see. If you see a lot of this inside the valve cover, like sludge, you have a lot of water.

well, i don't think i've ever put any coolant in my truck. if i have, i don't remember when. point being, i'm not having to add coolant. so i would assume that means it's not pouring into the cylinders.
i'll try your test.

BobsL...good point.
Or
-You can drain some out and have it tested. Some local truck stops have on the spot sample testing. Or you can always send it out to a test facility but it takes up to a week or 2 sometimes.
-Let the truck sit overnight. Water/coolant will sink to the bottom. Drain some out and see what it looks like.
