I had blue smoke coming from my exhaust what does it mean? I know that Black smoke is often times a result of too much fuel and not enough air in the combustion chamber. And I know that Gray smoke is caused by brake fluid. And it generally means that your brake master cylinder is bad, and is getting sucked through the vacuum brake hose... but I don't never seen blue smoke from my exhaust before and I have no idea what it means...

yeah, its more than likely oil. I wouldnt go as far as to say the engine has very limited life left, thats nonsense. It may just be bad valve seals, which are dirt cheap. Run a compression test on the engine, that will tell you which cylinder/s is leaking.
