Appreciate any suggestions out there. Recently had new seals, gasket & o-ring replaced for oil leak; when car has sat for a few hours have huge plume of blue smoke from exhaust; it has been over a week since repairs were made so am unsure if smoke would have anything to do with residual oil from leak. Am told that there is a crack in oil pan next to drain plug. Would this cause smoke from exhaust or is there something other than seals, gasket & oring that mechanic may have missed?

The crack in the pan is a non issue here unless the crack is over the exhaust pipe and drips on the pipe.

You mention seals were replaced and those were the seals on the crankshaft? You have not had the head serviced right? This sounds like it could be valve guide seals that are failing. They allow the oil to leak in to the cylinder. There could be something else. Have you had a compression check done on the vehicle?
