    Olds 307 Distributor shaft oil seal


    I have a 89 Brougham with an olds 307 that burn a bit of oil, i noticed this comment on "The Brougham Society on facebook"

    "There was an issue in these that caused them to use oil. From what I remember it had something to do with a seal on or around the distributor shaft. Caused major oil burning, tho. Otherwise a good motor."

    Anyone on here that can confirm this, because i can't find it anywhere myself.

    The early Olds engines had an "O" ring seal. Don't remember what the 307's had and I am not sure what effect they had on the oiling system.

    An oil leak thru the shaft of the distributor would pump oil up onto the module plate. It would not affect oil consumption.
