Default distributer noise

--------------------------------------------------------------------------------
i heard a clanking noise at idle, and goe's away when engine revs, i checked the flex plate, checked the rockers, it sounded like it was coming from the distributer cap, so i took the cap off (THIS IS HEI)and you can lift the rotor upwards (it clanks) and when you wiggle it it makes a clanking sound, loud.. this is the sound i believe i hear, i dont think a rotor should move that freely upwards or by rotating it back and forth... is this true, could i have distributer problems?

Rotors typically have motion. The rotational motion is the fly weights for the centrifugal advance. Some up and down is also normal.

Shim the drive gear down to 0.007" to get rid of the up-and-down movement. The distributors I have rebuilt have about 0.018-0.025" initially.
