Thanks for all your comments. Would have posted sooner but couldn't get back on yesterday. Unfortunately, do to a combination of stupidity and bad luck it turns out the motor has seized. We lost the oil plug, oil drained out, engine died.
We are giving our friend who was driving at the time the benefit of the doubt that there were no indications that hey maybe I should stop driving now before it actually died.
So now we are pricing a rebuild, versus a used versus a new, etc. Anyone have any experience and/or recommendations on this.
