Gents,

Please pardon my stupid question.

Is there a PCV (Positive Crankcase Ventilation) Valve in the 4.0L Jaguar V8 engine, because I can't find one? If there is one, where is it located/connected?

Otherwise, by what means is the Jag 4.0L V8 engine's crankcase ventilated?

 

Yes. It is through the "part load breather" and Full load breather" They are on both cam covers, full load is no the air cleaner side, and the part load on the other. Easily spotted by their "accordion" hose look.

 

Here is a TSB on cleaning the PCV.

Thats only pre 2003. Confused me for ever till I found the PCV valve on later models

 

Are the part load breathers replaceable? Mine is broken in valve cover and I can't find replacement except by buying complete used valve cover

 

How do I know if my PCV valve needs replacing. I found one for $51 but don't want to waste money if I don't need.

Thanks

 

Is it causing a code? If not it's okay.
