    Default 1.9 CDTI (150) Back pressure

    I have just fitted a pipercross Air filter and done a few checks around my engine as normal, oil water etc..... AND

    i took my oil cap off where you put your oil in and i can feel quite a bit of back pressure also spitting oil, is there and reasons for this cause i though if that happens its an OLD engine?

    This is an 06 vectra.


    All feedback welcome


    Thanks

    yes it should spit a bit. Healthy sign IMO, it means the oil is getting to lubricate the top parts of the engine. If were a gush like striking an oil well, then I would be concerned.
