I presume you have a turbo diesel, not a turbo gas engine... You also don't
say if the oil sprays out on to the engine or radiator, or into the exhaust
(causing lots of smoke)

1. Lets assume its external spray. The turbo has an in and out oil feed
line. Both lines have copper crush washers under the banjo connectors. Take
the banjo bolts out and replace the copper washers. If this does not fix the
spray, then you have to take the turbo off and inspect the impeller bearings
and seals.

2. If the problem is smoke, take the turbo off and replace the impeller
bearings and seals, or get a rebuilt unit.
