1987 Shelby GLHS #0958
I can't tell you how many friends I have seen install a catch can with a line 1/2" or smaller, and they are suddenly pushing all of their engine oil out all the time. In cases where people have installed a road draft system, the car will be smoking from the exhaust constantly. I've always had stock PCV in place. I'm guessing if you have a higher mileage engine and you don't pull atomized oil out, you end up burning it. I guess I'll see what happens at some point here.
