I had a very similar issue recently after an oil change, the day before I was due to drive to Switzerland my oil dumped just after start up
I had done around 45 miles since the oil / filter change before it decided enough was enough. I initially assumed it was leaking from the sump nut as I had used a washer this time, but after I had crawled underneath I realised that the oil was escaping from the filter. The filter was still tight but when we removed it the plastic gasket had come slightly adrift... And most of my oil was on the floor
We re-attached the filter, filled with oil and I made it the 1/2 mile home.I assumed maybe it was that I had not applied enough oil to the seal when fitting..? It seemed to still be tight, but was it too tight..!? Or as suggested the area that the filter attaches to was in some way faulty / damaged..?
The filter was purchased from the website, CMB11323 and it was a few mm shorter in length than the one I removed which was also the exact same make and model no but with an additional code of MD069782. I cannot find this code on the slightly shorter filter that had failed after about 45 miles.
I managed to replace it the same day with a Blueprint ADC42110 (labelled up as a Nippon) which again was slightly longer than the one that had sprung a leak?
We managed to clock up 2000miles after the smaller filter was changed and my paranoia of the filter leaking again is slowing dying off!
Could there may be 2 types of CMB11323 filter in circulation?
Hope this helps
