AHA blew all of it's oil out of the bottom of the engine

[Chris Talley]

Yes the oil cooler is the water cooled type. I assumed it was a failed
seal, it just kind of made me sick to my stomach seeing oil pour out  like
a waterfall. I have been using
5w-30 I think that should be thin enough, it has been super cold for a few
days I am sure the oil was pretty thick. I think that seal may have been on
it's way out for a while and the cold oil was the last straw.

Thanks, Chris.
