Well before a full top end strip down I’d like to start with basics!! I put a rubber glove over the oil filler and started it up and it blew up like a bloody great balloon!! Is it possible that the brake vacuum pump could leak internally into the rocker cover? I’ve been checking various vacuum pipes and have found nothing of note yet.
