1st time using seafoam did I do it wrong?

[fisher580]

just my two cents, ive gone 1000+ miles on seafoam in the oil, never a problem with 4 grand prix, 2 cavi's and an f150. well one problem, it will find every oil leak your car has

This. You should be fine.
Also you didn't get any smoke out the exhaust because you didn't put any in the brake booster.
