Im having trouble with my pertronix flame thrower distributor, driving around at lower rpm no problem, when i take it to the track about 3/4 track it starts pumping oil out of the vent hole on the distributor, so much that it gets on the headers and make alot of smoke. Has anyone had trouble with these? ive had it almost 3 years and it just started doing this, ive had it apart and cant see any reason why its doing it. My motor is a 355 chevy, have to run a small cap distributor its in my 1955 chevy wagon. Also theres no crank case pressure ive checked that thinking that could be it, but it doesnt push any oil out of the breathers or dip stick tube. This is driving me crazy, i shift the motor at 6400 rpm, its also got a solid cam in it. any suggestions would be appreciated thanks John.
