Servicing PCV on 2001 s80 2.9

[lincolnshibuya]

If you have a 2001 2.9l s80 here's some pointers when I did my PCV replacement.

removing the intake manifold is easy, #10 bolts mostly. It just requires different sizes of extensions and wooble. I re-use gasket for the upper and replace the intake manifold to head gasket (not necessary but I bought one just in case)

injectors don't need to removed, just remove the wire connectors out of the way so that you could move the intake manifold to the side. Not removing them saves you buying new o-orings for the injectors.


disconnect the fuel rail from the bottom, not in the fuel rail. There's a connection there where you could insert the fuel line disconnect tool and remove it easily. (see the circular white tool in the fuel line near the starter)


better to use those worm gear clamps than the factory clamps, when I removed the hoses they just slid out because the rubber shrink and the clamps are way too loose.

my breather box is not clogged just has lots of milky oil inside that hardened and some of them mostly in the hole on the engine side. I'm assuming the previous owner doesn't do a lot of driving, just short trips which is not good for the pcv system.
