Got everything to gather , used a 65 vette PCV and eng runs smooth at 800. Would like to find a pn for the orig PCV as it has threads on both ends to make a cleaner install. checked the vac at the PCV and its 17 . I tried to read at the dipstick tube but got 0 ,Put some tape over the valvecover opening and it detents a little and with my hand it feels like vac there.Could probably make a plug for it to test vac but don't know what a good reading would be. Any ideas?
