My starter has not been engaging. It has been winding...after about the 10th time it will engage. I took the starter off today, and found metal filings inside...looked to be wearing a little. Anyone have any ideas what was going on? I also have what seems to be a rear main seal leak, and dirtying up near the starter, someone suggested my starter might just be dirty, and to give it a cleaning and try that. Anyway, i replaced the started, seems to work fine so far, just don't want it to go like the last one.
