Engine Trouble?

Hi All,

Ive been looking at getting a 9th gen ford f250 for quite a while now and I found a decent truck that I went and took a look at yesterday. However, when I checked the oil, the dip stick was milky at the top and you could see water drops on the bottom. It was enough that you couldn't see where the oil level was even after cleaning it and rechecking multiple times. We started the engine and idled if for maybe 2 minutes and when I rechecked the oil it looked clean (though at this point it was dark and I was using the light on my phone to look at it so I could be wrong). To add to my worries, the owner stated that when he parked it back in April, it had a full radiator of fluid, but now it is very low. He has been running it maybe once a week just to keep things from becoming a problem. The oil level was not overfilled but was on the higher side of within limits. Most of my experience is with gas trucks, and if this were a gas truck, then I would be worried about a cracked block, cracked head, or blown head gasket. My understanding of these engines is that they are literally bulletproof, so I was a little surprised about this finding. Any thoughts are appreciated. Thanks in advance.

welcome to FTE.
it could be a problem, or it could just be condensation from sitting.

Could be bad oil cooler seals the only way to see is to pressurize the cooling system.

I have read elsewhere that by feeling the pressure in the upper radiator hose you can get a sense of if there is a leak between the oil system and the cooling system. Would this be true about a cracked block/head or blown head gasket?
