Your problem may be back preasure, not vibration. Di ya'll leave off any hoses while trying to make his engine pretty? I did this with a 351 Cl years ago and got BAD blow back....mine wasn't the dipstick but preasure will escape at the weakest point....his might happen to be easier to blow the dipstick out. So I guess the short version is...If ya left off any hoses that were coming out of the original covers and just plugged in those rubber gromets instead, I'd say thats the problem! :beer
