oh

just getting a few seconds of smoke from mine on startup.

Its done 3.5k on a rebuild, head has just been re-fitted as i had to change a valve guide, so therefore its got brand new stem seals. I re-built the turbo myself while the head was off, with a minor service kit which had all new bearings, thrsut bearings and oil seals.

I also replaced the oil return hose as the old one was split, but i used to a samco 90 degree elbow, was a nightmare to fit looking at it now, a 45degree would of done it better. Could possibly be getting a build up in the pipe??

Is oil in the boost pipes a reult of oil pressure building up in the turbo?
