Unless I missed it I haven't seen anything about how long the car sat since it's last run when the oil level is checked.
I rebuilt my 944 2.5 NA race motor winter 2016 and a installed an IJ Teflon crank scrapper along with two other 944 race pals.
Checking the level 2+ hours after shut down we are all at the proper level. After a day+ we gain close to .25 quarts on the stick. Our hunch is the zero clearance scrapper is slowing flow into the pan.
