Excellent build thread, top notch! How much oil pressure are you throwing into the turbo?? Have you got a restrictor on there? If not it could be why you are killing them. 70+psi of oil pressure is pretty much guaranteed to goose your seals. Just a thought.

There is no restrictor on there. the oil feed is running from the oil pressure switch so 5 bar of pressure when its cold and 3.5 when its hot. Were would i get a restrictor from ill give it a go. Rich.

5 BAR!! cheezums!!! I think you only need 1 BAR tops on a journal bearing turbo, a lot less if it is a ball bearing jobbie. OEM turbo'd cars have a restrictor in the line from the factory. If you know what make and trim your turbo is you could find the normal operating pressure from the manufacturer perhaps, I bet it's a fraction of what you are running.

Hope this helps

I don't quite know, most i've read about seem to use the 0.065 thou aperture, i'm not an expert at these things but i'm finding out as much as I can like you. I'm fumbling through my build researching each problem as they arise, and a lot have arisen too. It seems like i'm spending my life looking at an LCD screen instead of a windscreen.

Can't wait to drive it.

Good luck, let me know how it goes and i'll keep updating my thread too.
