Blowing that blue smoke.

History of the car: 2004 6spd. Engine is a ReMan replaced around 60k post 2008. Bought the car with 85k on it in 2012. Current Mileage is 114,7XX. Have not had a compression test done. Oil changed regularly and coolant just flushed and changed within past 2 months. Replaced coils, plugs, wires last summer. Have never over heated the car. Replacing fuel pump next weekend as I suspect its on its way out. Was not running pre mix at time of incident.

Current mods that could effect diagnosis: Mazsport Midpipe.

After some spirited driving in the mountains last night, the car started smoking pretty bad. It has always done a little blue smoke every now and then, but this was different. The car still starts fine hot and cold, no issues. Upon initial start up (cold and hot) it smokes pretty bad and then eventually stops. From what I have been reading, I'm thinking its an oil seal failure. Seemingly specifically the Front.

So my questions... Is this the likely issue and how much is it going to cost?

I have been reading this is not a task to be taken lightly if done by oneself.

Thanks for all the help. Let me know if there is any other information needed or any way I can better diagnose the car myself. I usually try not to create new threads but I read through posts for an hour and couldn't get a real specific answer for my symptoms.
