Hi guys hope you can help?
I have a peugeot 306 with a 8v turbo lump fitted which was done by Ecosse.
I have started to notice black soot on the back of the car and all the piston's have oil on them when i removed the plugs.
The engine has adjustable boost between 5 and 15 psi and is running JE piston's.
From searching you site i'm thinking it's the turbo oil seals but just wanted your thoughts.
Have done a compression test and thats ok.
Your advice please
