One thing I do is elevate the tailwheel so that all that oil in the back of the oil pan flows forward and drains out with the rest of the oil. Makes it easier and cleaner to do the oil screen too

Great video.
Just curious which model challenger oil filter are you using with your up right oil filter adaptor and how long have you been using that? Any feed back on it would be great.
I have the B&C up right adaptor which calls for CH48108 oil filter. These have an anti drain back so they don't drain out between each start.
My understanding is that some of the models have the relief valve, unless by relief valve you mean a drain valve from the body.I punch a small hole in my Tempest filter adjacent to the safety wire ring and let it drain overnight. The next day I put a piece of tape over the hole and remove the filter with minimal or no drip.
The tape over the hole prevents any remaining oil from dripping out once I turn the filter over after removing.
It would be nice if your challenger filter had a "relief" valve.
