Is this at all effective. I saw it as a mod on this site. I'm familiar with Saab's technical pcv breather system. I've owned volvos in the past they have the same oil trap pcv system. Well I installed a aftermarket breather on the top of the engine and capped off the tubing on the oil trap where it goes into the pcv valve. Well a lot of smoke is bellowing out of the oil cap and the breather, is this normal?
Quick answer = NO, this is not normal
Not so quick answer.
I have found mention of PCV kit on this site, so far on page5 of the Tech talk . Here http://saabworld.net/f15/pcv-kit-9-3-a-27999/
It then gives a link to a PDF of a Saab Technical Service Bulletin(TSB-210-2418ed. 4 from 2006)regarding the renovation kit for crankcase venting.

Since I have one on order from Saab, I have been reading quite a lot about it from various sites. I could not recollect any of them making mention to blocking off the oil trap. Thinking I had understood it incorrectly I re-read the procedure, and found on page 5,numbers 20 & 21 referred to
(20)The crankcase ventilation hose must follow the route of the lower coolant hose through the intake manifold and then on to the oil trap. And (21)Connect the oil trap's upper hoses.

Check Valve (PCV) Information
The white & gray check valve located in the upper hose going into the valve cover is a one way check valve. The purpose of this valve is to prevent boost pressure from going into the intake manifold when the turbo starts to spool up. To determine if you positioning it correctly simply blow through the valve. No air should go into the valve cover after the valve is inserted into the vacuum line. INCIDENTALLY the valve is not a PCV valve. Many people think it is so we put that info in the title for search purposes.
Have had a quick peek on Volvo forums too now, and as yet have not found anything , regarding blocking off pipes to the catch can assembly.
Perhaps you might want to re-familiarise yourself with SaabTechnical PCV breather system.
Hope this helps
Cheers for now
