there's an o-ring in there.... cheap fix

which engine code is it and do you have water pipes going from water pump to the filter flange?

with that info can give you part number for the o-ring

part 19: 038117070A

It could be the housing retaining nut is loose. You'll have to take the filter off to get to it, it's the nut on the threaded shaft that the filter itself screws onto.

i took the filter off, and the nut that holds the box was slightly loose so i tighten it. put the filter back, started the car but the oil was still leaking but not as bad as it was before tightening the nut. So took the filter out back again, took the nut off, took the O ring off and there were slight few cuts on the inside circle of the O ring so I believe needs new ring.

Also part number would be great

there are 2 small coolant hoses connected to the box as far as i can see

many thanks for help
