Woody - Thanks for the promotion!
I have had my S/C and IC completely torn down. Removal is not a very difficult task. At that time I took my IC to a radiator shop to be cleaned.
There was what I would consider a good amount of blow-by oil - but being that we use synthetic oil - it was not the caked on sludge type of coating that you might see on your on the bottom of your oil pan.
I decided at that time to use Brandon’s design for an air/oil separator and while it is effective - at high RPM's it was not relieving crank case pressure and the oil dip stick would slightly dislodge and oil would dribble out and down the tube.
As you suggested Woody - I went with a thicker o-ring on the dip stick and I even tie-wrapped the dip stick in place. This solved the problem - but I still worried about built-up crank case pressure. So I re-connected the larger breather tube from the DS valve cover to the SL55 (or SRT6) Y throttle body tube that I had capped off and left the two smaller tubes connect to the oil/Air separator. I still trap a fair amount of oil - but I figure I'm still getting some blow-by at WOT.
I would not want to spray any cleaner thru the SC and take a chance of damaging the Teflon coating on the S/C screws..
I also decided to heat wrap that puppy to try and prevent heat soak from the e engine. I do think the wrap is effective in prolonging and even preventing the engine from cooking the IC casing - but the heat generated from the SC mounting points still soaks through.
I look forward to seeing more of your separator and who well it will work when at WOT....
