Got to ride
Since I need to import my Purolator filters from the US, I usually buy 5 or 10 units at a time. The defective filters we've been discussing were part of my most recent order of 5 filters.
The first filter of the new type leaked, leaving an oil patch across half of Japan since this happened during my recent ride (my FJR was marking it's territory I guess). Anyway, I happen to currently have both the old (good) and the new (bad) types of this same Purolator PureOne 14612 filters, so having just done an oil change I figured I would try to identify any other, more significant differences than just the slight difference in the color of the gasket, since that's not a very good indicator as the rubber can discolor over time...
As you can see from the pics, it looks like the new version of this filter has the inside threaded part protruding, almost concave shape, vs. the old (good) version where this section was distinctly convex, hence I believe enabling that last 1/4 turn which created a secure gasket seal.
I have just used one of the old type so will be able to report on it after this weekend's ride.
Two of each type side by side, just to eliminate any doubts, all 4 of my new type looked the same. The new (bad) filters are the top two.
A close up of each version of the filters, the new (bad) filter is on the left in this pic.
And since I still had one of the rather old version of the 14612 I compared against it too, same conclusion...
