91 940 turbo...turbo is leaking oil from seals but holding boost..

dry averages (3 readings per cylinder)
reading variens from average for all cylinders

1 145 psi -8.7%
2 155 psi -6.4%
3 165 psi +3.9%
4 170 psi +7.1%

guage is screw in type of average to good quality (draper). cylinders are numbered from front to back of engine.

wet readings within 6% of dry readings...note not too much oil induced! (couple of squirts from an oil can...)

all the plugs seed a little coked up, cylinder 1 was worst...

bear in mind this engine has been breathing up to 1/2 litre oil per 100 miles on a fast run...

anyone got any thoughts or comments?
