I’ve encountered a problem doing an oil change,,changed oil filter,and after a couple of tries reseating it,,I have an oil leak..it’s awkward to see if it’s from the filter cup,or the filter mounting gasget,,,can I assume if it’s from the gasget,there would be a continues leak down engine,,as it only leaks after a drive from the cup area,,I can’t see where exactly,it’s leaking,as people may know how difficult it is to reseat the cup,with all the ancillaries round it..thank you

Is your filter the type with a plastic cover done up to 25 Nm and a large O-ring seal on it ?

Yes it has the plastic cup,,the rubber seal does fit into an angled groove.

The filter is a PITA to install on these engines.

I'd suggest removing the filter, checking for any damage to the filter, o-ring, cap and housing, reseating the filter, and refitting.

Fit the filter to the engine, not the cap. Make sure the peg on the filter engages with the hole in the housing.

On our 1.6 hdi Cactus to get to the filter I remove the air duct and then undo a clip on a water pipe so it can be moved a bit and squashed and the cap undone. Still tight for space. The filter element has a lug on it that goes into a hole and as shtu says, fit it to the filter body and not the cap first. After removing the old one, the new large O-ring goes in the second slot on the cap and I smear some oil on it before fitting the cap back and also in the body. Do by hand first to make sure the threads are not crossed and then fully tighten using a torque wrench to 25 Nm.
