I'm still chasing an oil leak from that area though Mudski.
It looks look the EGR valve or something in that vicinity. It only does it under load and is only a fine spray. I'm not losing any oil at all so its coming from the vacuum EGR system somewhere.
I will have another look on the weekend.
I also have to fix the fuel pump as it is leaking fuel (and getting worse) so I have to play mechanic again this weekend before we take the Patrol away for two weeks in April.
But you are right, It is good to get things fixed and working properly.
