Default 850 Leak Issues Please Help!

I really need some help trying to figure out where this oil leak is coming from and where this smoke is coming from.

I just got done replacing the PCV breather system. Got it installed and the car running again. Now I have an oil leak that is dropping some major oil. I have circled in the picture where it is coming from. It is on a 96 850 turbo. The oil is coming down near the fuel lines on the passenger side. The picture posted was taken from the passenger side wheel well. I have also taken off the camshaft plastic housing and the oil does not seem to be coming from in there.



Smoking issue: The motor is smoking from under the turbo heat shield. I have not taken the shield off yet. The car was smoking from there before I replaced the PCV system. I thought that replacing the PCV system would take the pressure off any seals or gaskets that were feeling the pressure from a backed up system. I am not able to drive the car at the moment. It is still on jack stands as I have the wheels off and am going to get new tires. Now that the PCV system has been replaced the smoke has doubled in amount. It used to take about 5 min before it would start smoking now it only takes about 30 secs. Could this be a seal that is bad and now that the system is breathing better it is spitting out more oil?

Thanks!

Make sure that the hose that comes from the PCV beather box to the top of the cam cover is secure. It looks like oil is coming out that hose and pouring down the side of the engine.

I've had luck locating hard to find leaks, by spraying the general area with gasoline, simple green, etc to get it really clean. Then starting from where I saw the leak and was able to trace it back up. Sounds like the oil is running dow a hot engine surface to smoke. A bright light and mirrow can reveal a lot. A hose or some other simple thing could have been moved or loosened when you worked in the area last.

Your picture is kind of disorienting but, if you didnt have the leak before you did the pcv then you must of missed torquing something back on. Maybe missed a seal?
