Turbo Leak?

[KrnAznEP]

I was just taking my intake manifold off to do 99 lifter change, but noticed a bit of oil leak around the intake manifold gasket. There were traces of oil inside the intake manifold (both top and bottom). I havnt had the car smoged yet, but there is a lot of smoke coming out from the exhaust pipe, not too much, but like those cars you see early in the morning and yes i did warn her up. As i opened up the intake tube that connects to both turbo i saw that there was little traces of oil in the rear pre turbo pipe. Should i be worried or is this a normal thing. Only reason why im questioning is because the intake manifold is for air not oil. Thanks!
