PCV job V70 and S70 non-turbo

[rspi]

The lower intake manifold bolts don't have to be removed, just loosened. The 2 bolts that hold the bracket on the bottom of the intake manifold can be removed from up top if you are a little flexiable. Also, the bolt that holds the oil dip stick tube. Try not to drop and loose an intake manifold bolt. The first time I did the job it took almost 7 hours because I had to run to the store twice to get tools. A good pair of long curved needle nose pliers and those funny clamp crimpers will be good to have on hand. Also, there is a fuel line that is very short and will likely not come loose will need to be replaced. Make sure you get FUEL INJECTOR rated hose to replace that small hose.

I am feeling comfortable with taking it on. Few questions...
Would oil change be a good first step after PCV job?
Do I drain before starting to take things off?
What parts in the kit must be oem/oes?
What make of part to avoid?
Which hoses must have fixed size crimp clamps?
