absolutely, a lot of phenytoin pumped IO (into the oil circulation) at the precise moment the bolt parted ways could have prevented the seizure.
(One would have to ask, as this is a known fault of the TD5, when was the last time the sump was removed and Locktite (re-)applied to the oil-pump bolt thread? It should be a regular service item!
More importantly why wasn't it a left-hand thread in the first place. )
