    my 1986 volvo 240 is filling the intake with oil through the pcv/flame trap system, is it blown rings or something stupid im overlooking. i have already installed a new pcv catch can but no difference was made other than it finally wants to idle again. any help appreciated.

    Symptoms
    smoking like a 4 cylinder 2 stroke engine
    hard idle/random rev spikes
    pcv tube filling intake with oil
    building excessive crank case pressure
