does your catch can vent to the inlet pre turbo?

 

No for testing purposes I took it off to see if im vending oil but im clean
Im not sure if I mentioned but im using a 1.5mm oil feed restrictor for the turbo
as the one precision recommended was 2.7mm on 3 bar car systems the rx7 is like 7bar oil so some friend recommended for rx7 to use 1-1.5mm so im using the 1.5mm

 

Just for the info if any one reads this
I have solved the problem with 1mm oil restrictor on the turbo
No smoke whats so ever....
