Thanks for the replies

Unfortunately, I had taken the oil filter off a while ago with out thinking to check for debris.

However, I have just whipped off the sump cover, got overly excited as all seems quite clean and didn't see any debris. Then got embarrassed that my eyes had missed the debris gathered on the bottom of the cover and around the oil feed pipe.
