Be very careful of the wires connecting to the switchover valves. I broke a wire and ended up taking it to dealer to located the break in wire. I would definately find a place to dip it, its a real messy job trying with diesel, brake cleaner etc. You are probably going to need the entire PCV system, those nipples get brittle and break when you try to remove them from the intake. Good luck, yours looks cleaner than mine when I removed it.
