What would cause the oil fill cap to blow off while a car is running?
its loose
You were mowing and oil came out the right side of your mower on your foot the cap came off did the engine blow?
Not necessarily. If the oil filler cap wasn't on tight it could have just vibrated off. If the cap is not on the filler tube it will blow oil out of the tube with a good running engine. I would refill the oil, tighten the cap, clean up the oil spill and try the mower again to see what happens. Chances are everything will be fine.

What happens if oil filter cap is loose?
Neither your oil filter, or the fill cap need to be loose, the filter should be screwed on as tight as you can get it by hand only, and the fill cap should fit snugly so it does not come off. If the oil filter is loose or too tight you can blow out the seal which will cause you lose all your oil.

It can cause your oil cap to blow right off, foam around the oil cap is more likely to be water or coolant. Get it checked right away because it can damage your engine. It's usually a sign of a bad head gasket, it lets water into the oil and oil into the water. Check your radiator to see if there is oil in the water and if the water is low.
