PCV Replacement HELP!

Post by Mikele82 » Sun Aug 25, 2019 10:35 am

So im planning the PCV fix but I see the method im following is missing a few steps.
ive made a slide show from FCP Euro s60 Video =

But :shock: only now i realized the xc70 2004 has some different things in the way, and maybe more under the intake manifold?
like whats the procedure on these A and B parts?

The B appears to be the fuel line connection, may find a detail here - be careful when releasing the pressure especially if the engine is still warm (not recommended) wear eye protection and some black rubber gloves www.youtube.com/watch?v=Cv7O8xHUiFc
The A looks like the pressure power steering line from the pump, you should have the line pressed in the pump, so it should have a small bolt on the side where it goes into the pump, just undo this bolt and remove it - have a rug underneath as it will spill a little bit of fluid

If you need the tools for the intake manifold www.youtube.com/watch?v=8CIVJu5E-Sk

I did never replace the dipstick seal or the injectors seal - be sure to have them pristine clean and use a little Vaseline when putting them back. Vaseline is OK because it's petroleum and these seals are in contact with gas which is also petroleum. Silicone is just as fine
The fuel rail may be hard to remove because the injector seals are stuck in there, I used a long pry bar to gently detach the rail.
