Crancase smoke, loss of power

Today I took my companies 2010 Polaris 550 EFI to the mountains for a job and while climbing a hill i slowly lost power. Shut it off immediately and pulled the dipstick and white smoke came rolling out. Oil was just checked last Wednesday and it was full. No warning lights came on or funny sounds, no knock. What I’m curios is to wondering if it is worth tearing into and possible rebuilding?
