Well, curiosity got the better of me after I encountered an issue with my 6466. I removed the unit, removed the drain and inlet oil restrict or and had a peek inside. Seems the entire rotating assembly is shifting forwards and backwards inside of the cartridge housing, almost as is there is a retaining clip missing. So on the blower I get, and it seems they don't really seem too keen on warranting it as I removed the restrictor. The fcuk? I wasn't born yesterday! I'll. upload a vid of it soon. I hope precision comes to the party on this one, same goes for PT.
