I just cleaned my PCV on my 4500.......the veertjie feels "pap", how should this feel?? If you shake the valve the insides are "loose". Like in a pap veertjie.

I have never stripped a new one, but mine's spring was also very weak.

Hi Petri,
Volg die rubber pyp van die tappet cover af tot reg langs die throttlebody op die inlet manifold, so silindriese adaptor megafter wat daar in skroef.
Checking Positive Crankcase Ventilation (PCV)
System
CHECKING PCV VALVE
With engine running at idle, remove ventilation hose from rocker
cover; if valve is working properly, a hissing noise will be heard as
air passes through it and a strong vacuum should be felt immediately
when a finger is placed over valve inlet.
Hoop dit help.
Dankie Derick.......moet mens die valve maar replace, wat is tell tale sings dat hy al moeg is??

Hi Petri,
Jammer vir die delayed reply, vervang, hulle is nie so duur nie, hoor by Nissan wat dit jou nou sal terug sit. Ek dink ek het in die omgewing van R 500 betaal as ek reg onthou….laas jaar Jan.

Nee, daai is deel van die vacuum sisteem.
Hy sit op 'n baie moeilike plek, tussen die intake manifold se "bene" en so half onder die carb.
Daar is twee rubber olie-pype wat uit die tappet cover uitkom. Hy sit in een van hulle, maar jy sal hom nie kan uithaal sonder om die carb af te haal nie.

Besides emissions control is there a valid reason to have a PCV valve on a (TB48) Patrol? Do the fumes need to be sucked out, as opposed to just venting by pressure, for any specified system-related reason. All the decades I've just run a plain "analogue" vent into the atmosphere, dangling open, or through a filter, or into a catch bottle, to let the motor breath. Usually one of the first things I chuck on a car.
