Sorry for the stupid question, but tonight was my first oil change on my 300CE. My quesiton is,are you supposed to insert the oil filter into the housing and the screw the cap on, or push the filter into the cap and then screw everything down into the filter.

I noticed the filter comes out with the cap (which was kind of strange), so I was wondering if the new one should go back in with it???

Its already installed, and nothing went BOOM, so maybe it doesn't matter!

Thanks,
