HI. Just noticed that there is a small leak of oil coming from my Blow Off Valve.
Is this a sign of something serious or normal?
Thanks for the feedback.

Its probably coming from the turbo oil seals. A little bit of oil is normal but if theres more than a 'little' then it would warrant some investigation. When you're standing at the front of the car looking down at turbo, remove the metal tube (2 x bolts) on the right hand side. Once that's off grab the turbo shaft with your fingers or pliers and give it a wiggle...there shouldn't be much play there at all! If there IS play (ie radial or in/out) then you need a rebuild

What Mike said, but it might be residue from your breather system too... If the engine is bit tired and breathing heavy/using some oil you will have some residue (I've got it on mine). Nevertheless do check your turbo.
