Oil at turbo Intercooler?

bbam

hi...
recently test drove a 2008 C4 Grand Picasso and was very happy with the experience..:)

I did notice oil round the pipe from the turbo to the intercooler , not lots but enough to catch my attention... of course the sales man said it was common and not a problem, car is being sold with 6 months full parts and labour cover only 38K miles..

Should I be worried?? Or Should I walk away

If there are no clouds of smoke coming out the exhaust then you should be ok.
The oil you see is from the crankcase ventilation hose that feeds into the air intake just before the turbo. This draws in the crankcase gases AND the oil mist and burns it in the engine.
But a big enough leak on the air intake could leak enough of that over time to cause a mess.

Some of these newer cars have the intake pipes joined with o-rings instead of the old fashioned jubilee clip. The o-ring can fail over time and leak a bit. I had a look to see what type the c4 has but no luck.
Maybe someone else can help there.

As above, its normal for diesels to get a build up of oil deposits in the i/c piping, its usually worse on cars that are only used for short trips.

thanks guys...
It was the only fault with the car I could see...

Just wish he'd offered a better trade on our Zafira... €4k for a 06
