Darn, I've got milk and I don't even own a cow!!!

Started up the D-17 and drove it around a couple of days ago.

Hadn't been run since last fall. Checked the oil the following day and its milky.

I ran it some last summer; used it on a bush hog for 12 or 13 hours in late summer.

No indication of water at that time.

I know there can be a few different causes for this.

I'm going to say its probably not the welch plugs in the head because the prior

owner had the head done just before I got it. 'course a plug could have been installed incorrectly, I guess? I'll check them out.

Maybe the head gasket; the prior owner had never had it running after installing the head and I never retorqued the head after I got it.

Anyway, I intend to change the oil and filter, retorque the head bolts and see what happens.

If I still got milk, I guess I'll drop the pan, pressurize the cooling system and look for cracks in the block webbing or for leaking sleeve O-rings.

Does that sound like the direction in which I should be heading?

BTW, I had a good tarp over the entire tractor all winter so I know I didn't get any

water down thru the breather or exhaust system.

Any advice from those who have BTDT will be appreciated.

I've got too darn many other things going on in the next week or so, which means I won't be able to get to it right away.

Contray to what I've heard, the water does not settle to the bottom; at least not in 3 or 4 days! It looks like a semi-permanent "emulsion" to me. LOL

It could possibly be condensation from sitting all winter.

I would go with the condensation idea first. It's the cheapest. Change the oil, watch it closely for a few days, if it is coolant, I have never seen coolant turn oil milky (others will know for sure), it you are running straight water in the radiator, then it could be either.

You don't get that much water from condensation. Definately retorque the head.Don't forget to then reset the valves.You can safely set them at.015 cold and not touch them again. And, the head getting "done" don't mean they changed the core plugs.Your game plan sounds reasonable to me.

We used to have a C2 gleaner with the gas 262 buda that would get coolant in the oil after sitting all winter. After the oil was changed in the spring it was fine till the next winter. Usually a guy is'nt htat lucky. My guess would be one or more of the o-rings on the sleeve have deterioated, unless the thing froze over the winter then you may have yourself a crack between the sleeves on the bottom of the block. If its real milky the pan needs to be dropped to get all that slime washed out of the crankcase anyway, pressurize cooling system and start lookin for drips.

Thanks for the affirmation on my plan. Thanks also for the tip on readjusting the valves.

It definitely didn't freeze ' cause she's got a good strong mix of anti-freeze in her.
