1999 S80 EVAP/PCV White Smoke Dip Stick

I have replaced the TPS, but it still stalls out randomly (replaced it with the magnetic TPS and followed all steps). Since I cleaned the CVVT solenoid (threw that code) and replaced the oil with semi synthetic, it was doing a little better about stalling out, bogging down when the A/C kicked on, surging, bogging down and almost stalling out when started, hunting at idle and during normal driving conditions, etc. but it seems that it may be reverting to its old ways. I may just get a brand new solenoid. I also need help because there is white smoke coming out of the dip stick and also when I take the cap off of the oil fill spot. I took off my PCV box, cleaned it out but cutting it apart (already had a crack so I said why not) and adding new activated charcoal in the respective spot, siliconeing it back together and cleaning all the hoses attached to the blow by box and the ECM (or hose attached to the ECM). After cleaning all this it still has white smoke pumping out of both locations. I need a diagram so I can tear the PCV system apart and clean it. Every diagram I find if wrong. Or someone can point me in the right spot to fix my problems? Any help is appreciated. Thanks everyone.

I highly recommend go for new PCV box along cleaning hoses attached to it specially hole attached to Engine where you put PCV.

Is that kit all there is to the s80 pcv system or do I need more parts? Also, could this be contributed to hard shifting or the car trying to go in gear?

the kits provide all the parts for the job
pcv parts and hoses, intake manifold gasket (since it has to be removed)
I have a 2000 NA S80, not turbo...less parts and complication

not sure, but maybe a vacuum problem could be affecting the shifting

if you have a vacuum problem/smoke problem after replacing the pcv, the charcoal canister and stuff around the gas tank and filler neck has a bunch of hoses, etc. associated with it as well
