Newbie Dumb question here. What does the catch can do and I why do I need it?
I'm guessing that it sucks oil vapors from the crankcase and collects it in a can so that they don't foul the intake valves. But I'm new to turbos, so I thought I should ask.
Do a quick search on it. Theres a few vids that explain it. and countless discussions on the web sites / forums. Even if you just searched for PCV to learn how it works, that would help you. Turbo's add more pressure to the cylinders which can create more 'blow by'. that makes the PCV recycle even more into the intake.
