Well, fitted one of Sean's filter kits with a new turbo to one of these horrid things this week.
Nice piece of kit, delivered very quickly, and we certainly have a fighting chance with the larger filter,can't believe the size of the original filter, cleaned everything out best i could, didn't seem too carboned up but tested the oil flow before and aft and it,s well within spec now.
Many Thanks Sean, woudn't be too worried about doing another now!!
