Boosted valve cover blow by options.
I am getting some oil spitting out of my valve cover fill vent, I installed a speed inc unit that puts a k&n filter on it but after a few hours this gets all oily. Are there any better options? Right now I run four -8an lines off the covers and old stock pcv to a vent, is that enough so I could cap the oil fill vent? or are there any other caps that are better or have a threaded line insert that I could run to another catch can?
