I had the autospecialists 1 with the new braided oil line, the shape of the fitment at the turbo and block wasn't exactly the same as the orig ford oil feed, it wouldn't stop leaking. So I thought I know, I will just fit the filter at the turbo. made sure it was tight etc, a week or so later it came loose and spewed oil all over a very hot turbo, thankfully I limped the car to a mates who was a minute or so away otherwise it was gonna be the breakdown truck.

Mines sat in my oil drain pan if anybody wants it. ??

I like the idea of a filter and cr turbos advised I fit one with my new turbo, but unless somebody came up with something better I would stick to a yearly oil change or every 3000miles whichever comes first.
