    Thumbs down oil out of the dipstick

     



    I have a chevy small block 302 that blows oil out of the dipstick
    while I'm getting on it or using the motor to brake. What happens
    is the dipstick is push out of the tube then oil gets all over the
    headders.
    it would be great if someone could help me out.

    When you rebuilt the engine did you go back with a high performance oil pump? Your problem could be too much oil on the top end and not enough flow area for the oil to return to the bottom end. If this is all full then you can't vent out the top end (cover vents, pcv...etc).

    If you pump more oil than intended to the top end then you have to give it bigger return holes to circulate.

    Just a thought...

    Problem couild be excessive blowby past the rings. Under load it overwhelms the pcv system, pressurizes the crankcase and suddenly your dipstick is making like old faithfull.

    Been there, done that.

    I'm not too familiar with Chevy's, but if it is like my Ford, I had to vent the valve covers. I have a breather on one side and a PCV on the other. I ran without a PCV and it was blowing oil out of the dipstick. I would turn the engine off and you could hear the air whistling out of the dipstick tube. I hated to punch a whole in my SVO valve covers but I did it anyway, and now there is no more oil spewing about, and no more air whistling through the tube.
