HI this is a quick explination of whats happening, on the front side of my EGR unit there is a drilled hole and this is weaping oil out front, onto engine breather and generaly making a mess :/

is this a bad sign or jsut best to ignore it and not let it bother me? or is it an easy simple fix thanks

I **think** this may be a symptom of your EGR's vacuum diaphragm being broken. Take the vac hose off the top, and put a.n. other bit of hose on there so you can blow down it. If air comes out of that same hole where the oil is emerging from, then your diaphragm is bust, and your EGR valve is doing nothing. If this doesn't bother you, you should at least blank off that vac hose as you'll currently have a vac leak if I'm right.

will this cause any damage to the egr piping under pressure all the time?.

i seem to rememeber people putting the egr blanking plate at wrong end of egr pipe causing it too split.. will this cause same effect, if it is leaking?

Any issues if it leaks?

I hope by doing nothing the diaphram is open and not disrupting air flow through the inlet?

No.

The EGR pipe can easily cope with the valve being fully open, or fully closed, as both occur during normal operation.

It is only likely to get damaged and leak if it is left unsupported at the top end (by being disconnected from the EGR valve), or by accidental impacts while attempting to undo nearby fixings.

The diaphragm is inside the silvery metal disc above the part the airflow goes through. If the diaphragm fails, all that will happen is that it will never be able to pull the valve upward, so it will never open to admit exhaust gases into the inlet.

I'm a bit doubtful about my original statement anyway. Perhaps the OP would do the test I suggest, which would give a yes/no to my suggestion in about 5 seconds?

At one point I used to service 30 of these engines a week... part of the service involved cleaning the engine bay and I swear every single one had a weeping egr valve... I wouldn't worry at all!

Oh and mines the same, I removed and cleaned mine but its just gets oily again straight away.

Well atleast that's set my mind at ease

When my diaphragm died the EM light came on. OOH it has shown oil weeps almost since new and nothing changed.
