Which nearly happened to mine, even after around 5 oil changes in 2 years and regular flushing i still had a blocked oil strainer in the sump causing oil starvation to the camshaft end. Citroen in my opinion should've done a recall and stuck a different sump on. Surely its their fault old oil congeals/carbonises as these engines run very hot and if youve got old tatty oil in there from years ago something will block eventually.

The amounts of oil seen on the pictures are way too high.
I suspect one of the following causes;
1. Overfilling of motor-oil.
2. The chicane-filter on top of the cam-cover is defective.
3. a "Valve cover gasket leak"..

Sorry to bring back the old topic, but I'm now experiencing this issue!

You mentioned that the filter may be defective, could you describe what would cause this? Is it that it needs cleaning? Or replacing entirely?

Have similar issue here with oil in inlet. Under warranty ther resealed cam cover so im asking is it possible they “damaged” that chicane filter (what is that anyway and can it be replaced?). Few times i have seen even very greasy inlet pipe to turbo.

I did read somew here that a 4mm thickness o-ring fits and is better to make a good long lasting seal
