i have a 555 bbc and using a gz motor sports vacuum pump. i drove it for the first time hooked up and noticed oil was spewing from the puke tank breather, enough to leave a puddle. talked to the owner and we figured that the oil feed line from the bottom of the tank back to the pump for lubing the pump was the culprit. so i blocked that off and just started it back up with a new carb and noticed some oil around the breather again, can't drive it yet. is the stud girdle is enough for a baffle or should one be added to the valve cover? it is on top of the cover also. if needed what is a good set up?i have cast aluminum covers. thanks, paul c.
