I am getting alittle fustrated I own a 900 T16 '87 and have jsut had the new
reconned turbo off for the suppliers to look at.  It has been smoking when I
have been coming off the accelerator. I thought it could have been a seal
going ( the turbo has only done 3K!). the turbo suppliers took it apart and
said it wasn't the unit but oil was coming in on the intake side and not the
exhaust side. and he suggested it could be due to too high a pressure
pushing oil from the cover breather into the intake pipe.

I have reinstalled the turbo and fixed a hole in the rubber air pipe that
connects the cover to the air intake.  After reconnecting every thing I got
a rough sounding engine which stalls and smoke everywhere.

Oil seems to be coming from another bit of the engine I dont understand
(sorry folks for the lay man mechanic) the exhaust manifold has a pipe
coming from it and it has a protective spring like cover which connects to a
thingy under the inlet manifold.  The oil is coming from the connection of
this pipe and the exhaust manifold.

Could anyone please shed some light on to this mess I'm in.
Thanks in advance

just an addition. The oil is coming out of the joins of the exhaust side of
the turbo the elbow and this connector.

when just revving the engine Im getting large volumes of unburnt fuel out of
the exhaust pipe.

before i put the turbo back  on none of this was happening just smoking on
releasing the accelerator occasionally.

I ve disconnected the breather pipe between the cover and intake pipe and
there is no oil coming through.

The oil's origin can only be the turbo surely?
