Exhaust smoke
 

I have done a turbo swop to my 93 RX7 and removed most of the emissions rubbish.
The car is running fine, but as soon as I deaccellerate the car smokes like a mother in law.
Why is that and how can I rectify it. I have left the oneway valve between the oil filler and intake.

I have the same issue. I e been told to put my PCV value back. I did and still the same smoke on decel. I have now capped off the UIM and iol filler neck. The other nipple on the oil filler neck is ran to a catch can and then to the primary turbo elbow. I have 3 in DP and MP no cat and RB dual tip. I can see oil seeping from the return line one the front turbo. I can figure it out. The last advice I was givin was the turbos were shot.... So what do I do??? Can I repair the twins or just say $&@&(! It and go single.
