PCV system question

Hi guys,

 

What does it mean when there's oil in the driver's side PCV hose? Surely that can't be good ....

 

Cheers,

 

Danny

    How much ? There will be a little oil in the plenum too but we're not talking pints of it .... right ?

    Enough to come out of the hose, travel along it to the back of the engine and drip onto some hot pipes below, giving me the occasional burnt oil smell and fumes coming from under the bonnet.

    PCV valves will collect a bit of oil as they recirculate crankcase pressure. But they are a closed loop system to do with emmisions regs. They should not be dripping anywhere. You may have a split/loose hose (s)?
