Prior to a couple of weeks ago the PCV was hooked up with a breather but I have added the Valve Cover to Air Cleaner base line. The vacuum adv line was hooked up to the most bottom left small port on a Edelbrock 1405 Carb ( this is standing at the nose of the car and looking down at the carb)does your engine have proper crancase ventilation? make sure it does!!!
does it have a pcv and breather? make sure it does!!!
where is your vacc adv line connected?
The previous owner had some type of line that was orange in color for the vacuum line. I changed it out this weekend to real vacuum hose.Are you sure you didn't use an old tranny modulator line?
I am putting in a new vacuum advance once I get the right one but was wondering if this has happened to anyone or ideas of what would cause this.
