i have blue smoke coming out of my tailpipes only after i drive my car after its been sitting a while...it only happens for the first few times i step on it and then it doesnt do it again, happens at part and wot only...what could this be...
 
burnt oil. If it accumulates while it sits that usually means it something like a valve guide leak: when your valve doesn't seal properly snug to the head's valve guide and oil slips down the glide after letting the car sit awhile so it accumulates a bit in the combustion chamber then burns once u start the car.
 
Is it safe for what? Your car is probably making less power now as there is oil along with fuel and air in the combustion chambers. You also need to start checking oil levels more since your burning more. Last...start saving for a rebuild ;-)
 
If it's doing it after only sitting for a few hours, then you are burning oil. You are either getting it through the PCV (run your finger on the inside of the throttle body to see if there's a build up), or piston rings. It COULD be valve seals, but I seem to remember the 4V's having that problem more than the 2V's.

If you let the car sit at idle for awhile and then it does it then it is most likely the PCV..
