i hate to sound stupid but ive tried pretty much everything

my 14b finally blew, oil was couple inches in my intercooler, slapped a new 16g on and it smokes more now then before the turbo let go. i am begging to think my valve stem seals are bad but wouldnt it of showed signs of them going bad, and not just letting go. i got a ticket for driving down the road and trying to clear the smoke out, i have had 3 sets of new plugs and ran all kinds of seafoam and shit from my work to clean the vacum lines, nothing helps
