Imagine driving your brand-new 3.6L Jeep Wrangler JL up a
steep, rocky grade. Your tires struggle to grip the rocks and loose soil, but
you persevere, steadily making your way to the top. You look back to see the
faces of your friends, hoping they'll be amazed and thinking the same thing you
are, "Wow, this Jeep can take on anything!" But you can't see them, because
they've been enveloped in a plume of blue-white smoke that's still billowing
from your exhaust. Instead of impressing everyone and selling at least four JL Wranglers in the
process, all you've manage to do is drive up a hill in a James Bond-esque smoke
screen.
Before you start worrying about piston rings and head
gaskets, you might want to investigate your CCV system. Blow-by accumulation
can wreak havoc on your intake and upper engine (and the lungs of anybody
spectating). Even a properly functioning CCV/PCV system can allow a large
amount of blow-by to pass
