i found oil on the turbo when i jacked up the car. i cleaned it and the next day there was oil there again.
so how long will my turbos last me now, or do i need to replace them asap?
they spool fine and there is no blue smoke.

 

There are other places where oil could be leaking other than the turbos. If the OMP lines going to the injectors are leaking then that can drip onto the turbos. I wouldn't start worrying until you see smoke.
