Any idea what size Allen wrench it takes to get oil plug out of the engine ? Just enuff room to get my arm under there,found water in the oil so I guess the heads coming off .Weeeeee fun fun fun.Not sure if water pump went up an she run hot or exactly what happened. I havent run the machine 30 minutes just loading an unloading. Pretty sure it was already an issue because oil looked like it was just changed.

Just find a bolt that the head fits inside, thread 2 nuts on & weld together, also fits other compartments

Is it colored with antifreeze? My thought right now is other than a active leak from a cyilinder jug, it could just be some condensation that collected from sitting.

Also, my experience is that the carbon in oil settles and can potentially look clear if the engine sits long enough.

I guess Im saying I would be skeptical in assuming the oil was 'just' changed.

Lot of the time Water in oil is a Precombustion chamber rusted through .They screw out of the head .
Manuals , check on Ebay .Try and avoid the reprint ones as the photos usually are not very clear .
