Well.., First..
I went with the B&C..., and a Challenger reusable filtter. During my first oil change, a friend showed me how to use a plastic grocery bag tucked around filter base to catch any oil trapped in the filter, and it worked great!
Then I continued the game of “wack-a-mole”
My cub sits on amphibs during the summer, and is/was very nose heavy.
Since I had to move oil lines anyway, and since I had the old heavy brass oil cooler hanging on the nose, and my engine baffling had seen it’s better days, I gave Randy Rubbert a call, and got the STC for the oil cooler move (that comes with new baffling,) and I changed to the light aluminum aft mounted oil cooler.
Then ... I decided to give the Sutton exhaust a try.
That made me have to remove a 2lb oil pan heater due to scat location, added to weight loss (a Zerostart that will be replaced with a Reiff.)
CHT shows no change, oil temp maybe a few degrees warmer? (No oat gauge), and no noticeable power difference so far ( also, got a new tach, so too many changes to be conclusive). I got the heat ribbon in the Sutton, and heat seems plenty adequate, but it has warmed up outside, so? Still couldn’t hold my hand near the heat outlet for long without melting my fingers.
All tolled I lost 14 lbs off the nose and moved the cg a 1/2 inch aft, and now I can shed 53 lbs of ballast while flying solo on floats.
I will not regret the filter adapter, and summer will ultimately tell about the rest.
