Hi Jim, First, how old is the oil that's in there? If the machine sat for a very long time in a moist climate, then perhaps condensation could account for it. (It's a long shot...), and it could have not shown up for a while because it didn't get stirred up off the bottom of the pan. Eliminate the possibilty of water getting in there via rain into an opening or service error or etc. Then try deaining just a tad of oil, if more than a tablespoon of water comes out with the oil, you'll have to look further. If not, then just change the oil and keep an eye on it. If a lot (say, more than a half-cupful) comes out you've likely got a leak. The next thing to check is to run the engine (don't run it hard with milky oil...)with the radiator cap open and look for any sign of compression leakage into the coolant. This will look like bubbles, or oil, or even smoke, not steam, coming out at the open radiator cap. A radiator pressure tester is a more accurate way of testing; a steady rise in coolant pressure in operation is a sure sign of a leak. If so, the likeliest culprits are a leaking head gasket or a cracked head or block.(aaargh!). It's difficult to tell which, but in either case the head has to come off. Also, check the spark plugs, (or injector tips?), and look for one that is a lot cleaner than the rest. If there is one, then that cylinder is the one with the leak. With the head off, careful examination of the head gasket and sealing areas will usually reveal a leak. In this case, a tiny gap is all it takes. If none is found then examine the cylinder bores and head, but a leak here can be hard to find; this is a good point to ask for help. The block and head can be pressure tested, but probably involves a complete teardown, and could still be inconclusive. Good luck. let me know what you find. Robert
