Should I be worried?

That engine this post was about ended up being smoked. Main bearings were trashed and the crank needed to be turned because of it. Onto a new engine now though and it’s humming right along.

Thanks for update!

Did you have any idea what caused that first “smoked” engine?

Was it a full rebuild with every wear component new or re-machined (bore, crank, heads, cam, oil pump…) ?
