mkoch Posted March 3, 2011 Share Posted March 3, 2011 Like the title says. The color in the picture is close to what it really is. The car runs. Does anybody know what causes this? mkoch Quote Link to comment Share on other sites More sharing options...
Idasho Posted March 3, 2011 Share Posted March 3, 2011 bad bearing/bushing. Is there any side-side play in the shaft? Quote Link to comment Share on other sites More sharing options...
naru Posted March 3, 2011 Share Posted March 3, 2011 Red dust is a sign the spark is jumping to ground inside the distributor. The red dust is iron oxidized by the arc. I`ve seen this in GM distys. Quote Link to comment Share on other sites More sharing options...
ruparts Posted March 3, 2011 Share Posted March 3, 2011 hi +1 naru, i have seen this lots of times , it can be cleaned from the metal parts of the dist with care, but probably time for new cap & rotor . Quote Link to comment Share on other sites More sharing options...
mkoch Posted March 3, 2011 Author Share Posted March 3, 2011 bad bearing/bushing. Is there any side-side play in the shaft? ...sigh... yes... I should have checked that instead of just looking at the thing. The only reason I saw the dust was my son wanted to know what a "rotor arm" was. He read about it in a book. I showed him the one on the Subaru. Thanks for the response. It looks like I'll have to buy a whole new distributor. Quote Link to comment Share on other sites More sharing options...
