I'll bet a quart of oil, that the reason the engine is running rough, is
because one of the plugs fouled, when the lad was over generous with the
juice to the crankcase---

Pull the plugs and check them out----

If the crankcase was that full with fluid, I think the darn thing would
hydro lock way before it could do any other damage---if the van wasn't
driven any big distance--which we don't know right now----

Later,
