Yes It was pulling oil through the guide. They made a plate for the carb and put air through the intake and it was coming out of an intake valve guide. Found this only after having re ringing the motor and having the heads off twice before for the water leak. Std tension rings now as I don’t want to run a vacuum pump on the street.

OFTEN ... I have seen oil being pulled through the threads for the rocker arm stud at high vacuum if they are not well sealed.
