I do not think and I hope you didnt do any damage??? Was your car on ramps when you chaged the oil? Sometims the elevation of the car pushes the oil toward the back of the oil pan and when you go start it, oil doesnt get to the engine quick enough because of the slant.

When I do my oil changes, I use ramps. But I do not add oil then crank and add more oil. I just add the correct amount, check level and start. Let it run and then take it down the ramps. I also do not use OEM oil filters. I just use the ones I can find at pep boys or auto zone. The OEM filter does look different from the aftermarket ones though. I have never had a problem with aftermarket filters. On occasion, I heard a slight rattle or faint knock but goes away instantly. I beleve that noise if from the valves and or some metal to metal parts in my engine. Now that loud knock of yours doesnt seem to sound too good from how I am imagining it but have the car checked out anyway just to be safe. The oil I have been always using was the 15-40 rotella which is a great oil. I had my mech open my valave covers to change the gaskets in the 560sel I have and he was impressed that the engine was sparkling clean, and thats with 151k miles!
