My old neighbor Bob came over one day explaining his 4-71 was full of water running out the dipstick, Rainwater at that.
I went over and dug around his machine for a bit, The rain cap was in place and closed, But the top inside lip of the muffler had a rusted hole inside the outer lip allowing the muffle to act like a funnel filling up the engine with water.
Long story short, We pulled the air box covers,Sprayed liners and rings with WD-40, Rotated the engine until the rings were free.
Drained the oil, Changed the filters, Added fresh oil, filters, battery, diesel, Fired it off for a minute.
Drained off the oil and changed the filters as this now looked like a vanilla shake.
Put more oil and filters, Ran fine, Bob went and bought a new muffler.
If you don't find the source of the water contamination you're back to square one, Look hard at the muffler and air filter housing.
