Oil around back plugs 2.5V6

Hi all,

I have had the great fun of changing the plugs on my Conny today, having twisted turned etc. I got them done.

Now the query, when removing numbers 2 & 4 plugs I found oil at the base of the plug holes. Having checked all around, starting with the back of the inlet manifold, I cannot find any signs of oil anywhere. Is there. any breather or oil pipes that could create this issue.

Having fitted the plugs and putting it all back together the car starts immediately with no problems at all. I have also been for a 20 minute drive, on return checked OBD and to my delight found DTC00, previously to changing plugs and a few other checks, I had an occasional misfire on 6 and Power viz issue.

I am not overly concerned but would like to fond the leak, if there is one.

Thanks in advance.
