Found coolant in my engine oil. Please Help!

Hello everyone. I was doing a oil change and when I loosened the drain plug about a 1/4 cup of clear liquid drained out before the oil drained. I'm assuming it's coolant. I took the RV to the Ford dealer and they're telling me nothing is wrong with the motor. Anyone else experience this problem with the Ford V-10?Any advice would be helpful. Thanks! My rig is a 2016 Sunseeker 2290S on a Ford E-350 Chassis with about 28000 miles on it.

Was the engine cold when you drained the oil? It's always a good idea to drain oil when it's warm and thinner so more will drain out in a given time. If the engine was cold and hadn't been run for a long time, I guess it's possible for some condensation to have formed in the block, but I've never heard of that large an amount.
Coolant is rarely clear, it's usually green or yellowish in color. The main way it can get into the oil is through a bad head gasket or cracked head, both usually the result of serious engine overheating. You'll have other symptoms like white smoke from the exhaust and coolant loss.
Big question here is if the vehicle was stored for a long time, like months. If it was run recently then there is some real troubleshooting in your future, pretty strange problem.

If you drained anything but oil from the oil pan You have a Problem, Yes it is engine coolant. cant be anything else. Is your oil milky or better yet the dipstick will have a milky crud on it.

Send a clean sample to blackstone laboratories for an oil analysis. They will tell you if it is coolant.

If you do a lot of short trips, it is possible that it is condensation that didn't get burned out.

Worst case, blown head gasket.

Good luck but def get that oil analsyis.

Thanks for the replies!

I changed the oil right after coming back from a long trip about 2000 miles. Always checking oil I never saw it appearing milky on the dipstick so it was a surprise to find something other than oil coming out of the drain plug. Hopefully it is just condensation, I guess I'll put some miles on it and check and see what comes out of the drain plug. I'll check out Blackstone Laboratories and send them a sample. Thanks again for the responses! Have a great weekend!

How long did it sit without running before you drained the oil and what was the environment like during that time? Although my first guess would be coolant, it shouldn't be clear. I definitely agree with having the oil tested if it's not too late. Hopefully whoever said your engine was OK did a cooling system pressure test, this can help pinpoint any leaks in the system. If you're not sure you can get a tester on loan from most major auto parts stores. The test is very easy, especially with good ol' YouTube around.
If it turns out to be water from condensation, you might want to check your other fluids, as in the tranny and rear end, to make sure they didn't pick up any water as well.
Good luck!

It sat for a couple of weeks before I changed the oil and I warmed up the engine before draining the oil out. The weather was highs in the 40's and lows in the teens. I can't say for sure that the liquid was completely clear, I know the coolant is light yellow so I might be wrong there. I'l look into the coolant pressure test and check the tranny and diff as well. Thanks DavidBo!

A quarter cup is a LOT of condensate, so it's unlikely to be that simple.

Blackstone will let you know if it's glycol, and if it is, get it fixed! Glycol is he!! on bearings!

Unusual to hear of this, as those V-10s have been pretty reliable powerplants.
