That's funny. I had one of those filter canisters that takes a roll of toilet paper when I was young . . . on my F-head Willys!!!
. . . which was before it spun the bearing.
Now, I can't say that the filter had anythiing to do with the spun bearing, because as I said, this was a chronic problem for both the flathead and F-head Willys. But I read a story later about filters that said that the toilet paper types worked poorly because the oil would make channels through the roll, and oil would then flow through the channels essentially unfiltered. This is in fact what I saw when I opened up my filter. I would never use that filter again, though I think I have it around somewhere.
