The unknown factor is…How much oil actually remained in the crankcase?
The dipstick can show no oil, but there can be…maybe…1.5 qts left in the crankcase, below the level of the dipstick. Or, there can be almost no oil at all.
So, the engine was running on very little oil, but we don’t know just how low the oil level was. When you added oil, how much did you have to add before it came up to the full mark on the stick?
When was the last time that you checked the oil level, prior to this incident?
(In other words…give us some clue as to how long the engine may be been operating with a low oil level)
When was the last time that the oil was changed, in terms of both odometer miles and elapsed time?
I am asking these questions because I am not optimistic regarding the longevity of this engine. However, if you can supply some additional information, we have a better chance of speculating whether the engine has a few more months, or perhaps only a few more days, of life left in it.
