Engine: B5244: - PCV Diagnosis

kymg · Dec 22nd, 2022, 22:11

Hi there,

I have a PCV question that you may be able to help me with.

The car – 2002 V& NA 240,000km. Pretty regularly serviced (7,500KM oil change)

The car currently being used by my daughter in another state and I am unable to assist so I have her description to go by.

The issue – we have been advised the PCV may require replacing. The car is at a mechanic. I have asked if he can do the glove test. He has not done that yet however, he did inform me that the there is significant suction at the dipstick. This would suggest, to me at least that the things are not too bad.

However, there is a light oil leak at the cam seal (timing belt end). This would tend to suggest that there may be an issue with PCV.

Would be interested too hear your collective thoughts.
Cheers

I did mine for the same reason. The PCV unit on ours (D5, 2007-2008 end of series 2) is difficult to change in isolation due to being recessed. However, you can make life easier by just prising the cap off and the diaphragm is seated just below it. That way the rest of the unit remains in place. Also you can buy the diaphragm separately.

While you're there (large EGR hoses off to gain access) you might as well chisel the mixture of hard and evil gloopy gunk out of the EGR. I'm still waiting to see if this makes a difference to ours.
