My 1990 chevy k1500 has a ticking noise that is coming from the distributor whem I advamce it it goes away and the high idle that it also has goes away and it idles normally any ideas? Also while the headlights are on no dash illumination but turn the highbeams on ilumination comes on I have already replaced the headligjt switch.

If you changed both the headlight switch and the highbeam assembly switch, wiring would be shorting out somewhere on that system. As for ticking, You have a minor valve problem there, i'd live with it on that old thing rather than rebuild that old engine

I sent you an email about a modderator as well
