Last night I also took apart and cleaned up the PCV valve. They're known to clog up apparently.
First things first, I removed the air filter housing to find this. Just had a 'full tune up' the seller says.
Its worse than it looks. Easy fix though.
So, under the air filter housing is the PCV hose and PCV valve. When I removed this rubber line, oil literally poured out. There was oil being sucked up into the intake housing too. I'm glad I took care of it.
All cleaned and back in place. The valve was totally clogged. I couldn't even see the hole in it when I took it apart. It took a fair amount of brake parts cleaner blasting to get it all out of there and freed up.
Now my 3 cylinder friend can breathe a bit easier!
